By Kirk Elliott – BadAss St Lucia Photographer Sharing My Saint Lucia with the World…
Greetings from my Sun Shinny island paradise where today I share all there is to know about the weather in St Lucia.
What You Will Learn From This Post
When planning a vacation I can only imagine that one of your most important concerns must be – “What will the weather in St Lucia be like while I’m there” …at least I know this is one of the first things I wonder about when I travel and I can only imagine that you are the same way too.
So in this post I share with you matters such as St Lucia temperature, St Lucia climate, St Lucia rainy season, St Lucia hurricane season, then we’ll check out some of the best beaches in St Lucia as well as some of the best places to visit when you get here.
I will also provide a brief overview of weather in St Lucia for each month of the year and each of these overviews will be linked to a more detail post for that month.
Okay So Who is Kirk Elliott, Why Should You Listen to Me and Why Am I Doing This Anyhow???
I’m sure by now you must be asking yourself these questions so I thought I’d answer them for you and set your mind at ease…
I am the creator of the award winning St Lucia Photo Tour where I take visitors on an amazing journey of exploration into the power of their digital cameras.
The question I am asked the most is “Kirk what happens if it rains?” So I figured that everyone else coming to St Lucia must want an answer to this question so I decided to create a comprehensive Weather in St Lucia review to help you understand what kind of weather to expect when you get here.
How To Get The Most Out Of This Article
Now because I’m covering so many things about St Lucia weather and St Lucia in general this will be a long article. To make it easy for you I have split the article into small bite size sections and I invite you to read it all, or just skim through the section headings and pick out those areas that answer your most burning questions.

St Lucia Climate
At a distance of 1558 km from the equator and 8442 km from the north pole St Lucia has a tropical climate with an average high temperature of about 30° C/86° F at sea level and an average low temperature of roughly 24.6° C/76° F. Further inland at higher elevations temperatures go down to an average of around 18° C/ 64.4° F.
Being part of the Windward Island chain St Lucia enjoys cooling northeasterly blowing Trade Winds that help keep the island refreshingly cool despite these high temperatures. As a result the weather in St Lucia is enjoyably warm except for the very short times when humidity is extremely high and the winds are low. At these times the air can be muggy and air conditioning is most welcomed.
Being this close to the equator the length of daylight hours on the longest day is only about an hour or so more than the daylight hours during our shortest days.
St Lucia Seasons
Unlike more northerly and southerly places that have 4 seasons St Lucia only experiences a wet and a dry season. St Lucia rainy season is June to November while the dry season runs from December to May. St Lucia Meteorological Office stats show an average annual rainfall of 1449 mm/57 inches of rain, with September being the wettest average month and February being the driest. All told St Lucia climate can be considered as typical Caribbean and ideal for a vacation getaway.
St Lucia Hurricane Season
St Lucia hurricane season is June to November, which is the same as St Lucia rainy season. St Lucia is sufficiently far south that most hurricanes bypass as they mostly impact the more northern Caribbean islands, Florida and the US east coast. Even when we take a hit the systems are usually weak and still disorganized and we tend to suffer more damage from flooding rather than from wind borne destruction.
While the impact of tropical weather systems can be disruptive St Lucia has an active emergency response unit that kicks into gear whenever natural disasters strike and essential services such as travel are hardly ever out of commission for more than a day or so. This is reassuring as who needs to be stuck abroad???
Weather in St Lucia By Month
This is a great time to give an overview of the weather by month for the entire year. To learn even more just click the link for each month for a more detailed review.
St Lucia Weather in December
Though this is the last month of the year I thought it was the perfect place to start. November marks the end of the rainy season so St Lucia weather in December brings visions of less rain as well as the joys of the festive season. Though we have moved into the dry season December often features a fair degree of rain, however it is unlikely to rain for the entire day as can happen in the preceding months.
St Lucia Weather in January
For St Lucia weather in January you can expect lots of sunshine, beautiful blue skies and cooling breezes from the North East Tradewinds. Early morning showers are common and don’t panic if the early morning skies look rather ominous as by 9:00 AM the skies are likely to be beautiful with no trace of the early morning make belief storm clouds.
St Lucia Weather in February
This is now the third month of our six month dry season so it should come as no surprise that St Lucia weather in February features the month with the lowest rainfall. February is also the month with the lowest daytime and night time temperatures, which should come as no surprise either, considering that this is the dead of winter in the northern hemisphere. The trade winds are even stronger than in January and this is a popular time for kite surfing at Cas en bas Beach on the northern end of the island and also down on Sandy Beach in the south.
St Lucia Weather in March
St Lucia weather in March features more of the same like in February and in March there is still little rainfall. In fact March is usually the 2nd driest month of the year and you get an idea of this just from watching the trees on the hillsides where you can see that they are struggling from lack of water. At this time we are often impacted by dust in the atmosphere which has blown across the Atlantic Ocean, having originated from dust storms in the Sahara Dessert over in West Africa. This dust makes the hillsides look a dinghy gray and can also make the horizon become indistinct when looked at across the ocean.
St Lucia Weather in April
So now we are into the penultimate month of the dry season and St Lucia weather in April can literally find us marking time as we anxiously await the arrival of the rains. By this time the average maximum temperature has increased by 1° C/2° F, which is also half of its annual variation. By April the average minimum temperature has also increased and all of this happens in part because day after day the land is being scorched without any rain to cool things down. However you are likely to love this weather as what’s there not to love about beautiful blue cloudless skies and no signs of rain.
St Lucia Weather in May
St Lucia weather in May is hot and dry. May has the third hottest average monthly temperatures and how early in the month the rains start to come gives an indication about what the rainy season may have in store. The northern and southern ends of the island are quite dry and over on Pigeon Island there can be bush fires sometimes from spontaneous combustion! However the center of the island tends to remain quite green as it enjoys some relief rainfall. This happens as air coming off the Atlantic Ocean hit the mountains, rise upwards causing moisture in them to condense and fall as rain on the western side of the island.
Daylight in May is longer as we approach June which has the longest day and shortest night of the year in the northern hemisphere.
St Lucia Weather in June
May marks the end of the dry season and June is the beginning of the rainy season. So with St Lucia weather in June you can expect more rain. However the rains don’t suddenly come pouring out of the sky, but rather gradually ease in. So you can expect more days with rain, but generally not so much that your vacation will be ruined.
June also marks the start of the hurricane season, however hurricanes usually appear later in the season and not this early on.
St Lucia Weather in July
St Lucia weather in July generally sees more rain coming down. By now the hillsides may have started to recuperate from the dry period and beautiful vibrant greens start returning to the leaves of the trees on the mountainsides. Average July high temperatures are about the same as June and May with this three month period being the third hottest months of the year with only August, September and October being hotter. By July the average rainfall is twice what it was in May. At this time of year the rains tend to come early in the mornings and again during the early afternoons. By now we have a fair idea of how active the hurricane season is likely to be based on the weather systems that have developed to date. However as stated earlier in this article, with St Lucia being as far south as it is we are less susceptible to hurricanes than the islands north of us.
St Lucia Weather in August
We are now into the third month of the rainy season and it’s no surprise that St Lucia weather in August features more rain than the months preceding. In fact on average August is the fourth wettest month of the year. With all of this rain August can also be humid. It is also the second hottest month of the year with an average temperature of about 31° C/ 88° F. Now the rains are likely to come both in the mornings and evenings and quite often at night as well. But as always there isn’t sufficient rain to ruin a holiday.
St Lucia Weather in September
St Lucia weather in September comes with more rain with data showing that this is the second wettest month of the year and also the hottest month of the year. So little surprise that the high
humidity continues in September. During this month it is not unusual to have 2 to 3 days in the month where it rains for most of the day. However these days are not necessarily back to back. In unusually wet years by September we down here are looking forward to the coming months when the rains begin to taper off. As a result of all of this rain September on average is the month with the second shortest number or hours of bright sunshine. This doesn’t mean that you will be in darkness, but rather that there’s a lot of overhead cloud that blocks out the sun.
St Lucia Weather in October
By October we are fast approaching the end of the rainy season, however there are some years when you would hardly know this. St Lucia weather in October finds the island lush green due to the rains of previous months. There tends to be lots of cloud cover and the days can be a bit muggy due to higher humidity compared to the dry season. There is a high probability of rain most days, however the rain tends to come as rain showers which usually clear up quickly so there’s no need to fear that your days will be ruined by rain. A twelve year rainfall study (2005 – 2016) showed October to be the month of the year with the most rainfall. Due to all of this rain and cloud cover October also features less bright sunshine than 8 other months in the year. On the upside of all of this October offers some really great accommodation and other local deals as this is usually a slow period for visitor arrivals.
St Lucia Weather in November
St Lucia weather in November signals the end of the hurricane season as well as the end of the rainy season. Officially these seasons end November 30th, however the rains don’t suddenly stop, but rather continue, though with less and less intensity and frequency but well into December. November is the month with the least number of hours of bright sunshine and also by this time the days are getting noticeable shorter with the sun setting closer to 6:00 PM rather than around 6:30 PM in the summer. By November St Lucia has come out of the spell of high humidity associated with earlier months as we are now impacted more by the North East Trade Winds. These trade winds often bring over dust from dust storms in the Sahara Desert over in West Africa and the dust can hang like a thin sheet of translucent paper over the hillsides for weeks on end. But with the weather as nice as it can be in November you probably won’t even notice this

Discover The REAL St Lucia
Rodney Bay St Lucia
Rodney Bay Village is a popular term you are likely to encounter when researching a St Lucia getaway. The “Village” starts at Rodney Bay Marina in the north and extends south to the Baywalk and JQ Charles Shopping Mall area. Rodney Bay Marina is a modern full service marina facility owned and operated by International Global Yachting. It comprises over 250 slips, berthing facilities for 32 mega yachts, bars, restaurants, banking and more…
Further south in the Rodney Bay mall area you will find banking, shopping, pharmacies, a casino and more restaurants than you could dine at even if you picked one or two a night over a 2 week stay. Rodney Bay St Lucia is the hip place to hang out while on the island.
Marigot Bay St Lucia
Sticking with yacht anchorages brings us to Marigot Bay St Lucia. Just south of Castries this hurricane hole is one of the safest anchorages in the entire Caribbean. The bay features a double harbour, a phenomenon that makes the inner bay really sheltered and safe should a hurricane strike. Marigot Bay is home to some beautiful vacation rental properties perched on the hillsides adjoining the bay as well as some restaurants right down on the bay that are truly worth visiting.
Map of St Lucia
One of the best ways to get an appreciation of St Lucia is from a map of St Lucia so I have included one here to help you find your bearings. International flights land on the southern end of the island and most visitors must trek up to the northern end of the island which is where most of the resorts are located.
Options for getting from the airport to the northern end of the island include taxi, a rental vehicle or St Lucia Helicopters
A map of St Lucia is also quite handy for helping you get your bearings. Most of the islands’ scenic delights are on the west. Check out the quaint little fishing village of Anse La Raye. It provides great photographic opportunities, especially in the morning when the sun shines straight across onto the ocean in a way that allows you to get stunningly vibrant colours.
To get this level of vibrance a circular polarizer is a must…something I get into detail on during The St Lucia Photo Tour…
Sulphur Springs St Lucia Soufriere & The Pitons
No trip to Saint Lucia is complete without a visit to Soufriere. Prepare to be blown away by the majestic awesomeness of The Pitons of St Lucia. Then there is the collapsed volcanic crater – The Sulphur Springs – St Lucia, which is touted as the world’s only Drive-in Volcano… not that I can figure why anyone would want to drive into a volcano!
The mineral mud baths at the Sulphur Springs is a must…go in feeling like 40 and come out feeling 18! Go in feeling 60 and come out feeling 24. And if those older ages mean nothing to you because you are way too young and way too cute, just imagine how you’re gonna feel after experiencing the therapeutic mud baths 😉
Pigeon Island St Lucia
While I’ve taken you down St Lucia’s west coast no introduction to St Lucia is complete without mentioning of Pigeon Island. Pigeon Island St Lucia with its military ruins dating back to the fighting between the English and the French must be one of the most historically significant military ruins in St Lucia, if not the Caribbean. With the English and French separately taking possession of Saint Lucia a total of 7 times each the island holds a record for the largest number of nationality changes of all the islands in the Caribbean.
Because Martinique, which has always been French, is a mere 25 miles north of Pigeon Island the island featured prominently as a strategic offensive and defensive position back in those days of Caribbean lawlessness, piracy and plunder. Today however the only remnants of those bygone days are names like the English – Fort Rodney which sits on the lower of the two peaks on the island; and Jambe de Bois (Peg Leg) Restaurant, named after the French privateer Francois le Clerc who reputedly used Pigeon Island as his hideout during the 16th century.
Today Pigeon Island is a Saint Lucia National Trust Landmark and a great place to “chill out” for half a day or so.
St Lucia Tours
With so much scenic beauty St Lucia is a great island for soft adventure. Trip Advisor St Lucia is a great place to discover things to do in St Lucia and the nicest thing about this is your ability to learn what folks who came before you really thought of their island experiences. Your most meaningful St Lucia Tours will most likely be those that give you a deeper appreciation of St Lucia’s uniqueness as opposed to being just another destination of sun sea and sand.
Best Beach in St Lucia
When thinking of St Lucia beaches a question I’m often asked is “What is the best beach in St Lucia?”
Well St Lucia is blessed with a variety of beautiful beaches and you are likely to find your favourite one based on the things you fancy.
So there are Cas-en-bas Beach on the northern end of the island and Sandy Beach in the south which are both great for kite surfing. Both of these beaches are on the Atlantic or eastern side of the island. For the kite surfers the weather in St Lucia is always an important consideration as they must know when the Northeastern Trade Winds are strongest so they can determine when they are likely to have the best wind action.
Then there is the ever popular Reduit Beach over in the Rodney Bay Village. With four hotels on this strip of beach, as well as it being popular with cruise ship passengers, this beach is oftentimes a hive of visitor activity.
In recent times Vigie Beach, just across from St Lucia’s small airport (G. F. L. Charles Airport) has become quite popular. The creation of a new food and drink vendors’ facility has cruise ship passengers flocking to this beach. This crescent shaped beach is about a mile and a half long which means that there is plenty of room for you to come and pick your spot.
St Lucia has long been considered one of the most exotic Caribbean islands. Being further south than many of it’s neighbor islands makes it more challenging to get to. But for those who make the effort to come St Lucia is such a welcomed treat. I hope that this overview of weather in St Lucia and all the other insights I shared have been helpful for you in planning your very own St Lucia getaway!
