By Kirk Elliott – BadAss St Lucia Photographer Sharing My Saint Lucia with the World…
This St Lucia Weather in May overview is based on my personal observation of St Lucia’s weather as someone who lives on the island. As a photographer I am acutely aware of the weather since 95% of my photography is produced outdoors. In putting together this monthly series on St Lucia weather I contacted the Saint Lucia Meteorological Office and they provided me with 12 years of monthly data for the period 2005 – 2016.
I wanna believe that this is thus the most comprehensive year round weather overview series for St Lucia to be found anywhere on the internet and I hope it is an invaluable guide to that burning question of yours: “What will the weather in St Lucia be like when I get down there???”

St Lucia Weather in May
So you plan on visiting St Lucia in May and already your are thinking: Just what is St Lucia weather in May like. Well here a a few things you’ll want to know:
St Lucia has two seasons – A wet and a dry season and the dry one runs from December to May. So it should come as little surprise that being the last month of the dry season this can be a transition month for rainfall compared to St Lucia weather in April. Then again some years the whole of May can be bone dry, but fortunately this is the exception rather than the norm.
May is the month of Jazz in St Lucia as the island kicks off it’s summer time monthly entertainment extravaganza. Jazz at Pigeon Island happens the second weekend of the month. This is a really great time for this outdoor festival as most years the rains never start coming in that early.

St Lucia May Temperatures at Sea Level
May is the third hottest month of the year in St Lucia for both the low and the high temperature. The average low temperature over the period 2005 – 2016 was 25.3° C / 77.5° F while the overage high temperature was 30.7° C / 87.3° F. However as is consistent throughout the year the high and low temperature difference remains at approximately 5° C / 10° F.
By May it is spring in most northerly and southerly countries so the idea of our warmer temperatures is not as great a draw as in the colder winter months. But who can resist the allure of a Caribbean vacation in a place as beautiful as Saint Lucia?
St Lucia May Sunshine
May is the month in St Lucia in which there are the most hours of bright sunshine, however it is just a wee bit more than there is for St Lucia weather in April. But when we turn to St Lucia weather in June the total hours of bright sunshine drops by over 30 hours. This is due to the fact that the rainy season starts in June, often resulting in more overcast days.
The days are also longer in May compared to previous months. In 2016 the sun rose at 5:42 AM and set at 6: 19 PM for a 12:36 hour day on May 1st. By May 31st the times had changed to a 5:35 AM sunrise and a 6:27 PM sunset for a 12:52 hour day.
St Lucia May Rainfall
May is the month of the year with the third lowest rainfall over the period under consideration. The average rainfall was 75.4 mm / 3.0 inches of rain. The amounts fluctuated considerably over the period ranging from one year with 23.9 mm / less than 1 inch, to another year with 191 mm / nearly 8 inches.
May can see water rationing by the Saint Lucia Water Authority, however with all of the major resorts having excellent water management protocols in place you are not likely to be adversely impacted by any of this. For those of us living in St Lucia by this time though, we are looking forward to St Lucia weather in June as this marks the start of our rainy season.
St Lucia May Weather Patterns
By May the Trade Winds are not blowing as briskly as earlier in the year. However you can generally expect bright blue skies with wispy white clouds, lots of sunshine and all the other fun things that go with such spectacular weather.
