By Kirk Elliott – BadAss St Lucia Photographer Sharing My Saint Lucia with the World…

Introduction

This St Lucia Weather in December overview is based on 12 years of data from the Saint Lucia Meteorological Office (2005 – 2016) as well as my personal observation of St Lucia’s weather. As a photographer I am acutely aware of the weather since 95% of my photography is produced outdoors. I have created a weather review like this for each month of the year and I hope that you find it an invaluable guide as you plan your Saint Lucia vacation and you ask that burning question: “What will the weather in St Lucia be like when I get down there???”

St Lucia Weather in December

When you think of St Lucia weather in December you most likely can’t help getting excited as you imagine the holiday season and warm tropical sunshine compared to cold grey snow if you live in a place with freezing winters. December 1st marks the official start of the dry season in Saint Lucia. However with the rainy season having officially ended the day before on November 30th it is little surprise that in December St Lucia weather is pretty much the same as you’d expect for St Lucia weather in November.

In St Lucia we only have a wet and a dry season and there is little difference in temperature between the hottest and coolest months here. This is wonderful for sun worshipers as it means that you can enjoy the outdoors in swimwear for your entire St Lucia stay regardless of time of year. Plus with the rainy season just ended the island is verdantly green in December.

St Lucia December Temperatures at Sea Level

Weather data from the St Lucia Meteorology Office over this twelve year period indicates an average maximum temperature in December of 29.5° C/ 85.1° F and an average minimum temperature of 24°C/75.2° F.
These temperatures make December the 7th hottest and the 4th coolest month of the year in St Lucia. It is interesting to note that there is only a 5° C temperature difference between the average highest and lowest temperatures. This ensures that the temperature is wonderful regardless of the time of day.

St Lucia December Sunshine

During the data period St Lucia experienced an average of 264 hours of bright sunshine; and as an example, in December 2015 sunrise occurred between 6:15 AM and 6:30 AM, with the sun setting anytime from 5:30 PM to 5:45PM for a total of approximately 11 hours of sunshine each day.

Shortest Day of the Year

December 21st / 22nd marks the winter solstice or the shortest day / longest night in the northern hemisphere – which is where Saint Lucia lies as we are 14° North of the equator. From this date forward the days start getting longer and the nights get shorter until the summer solstice in June. At this solstice the day is longest and the night shortest, then the cycle starts all over again.

St Lucia December Rainfall

Over this 12 year period December was the 7th wettest month in St Lucia, experiencing an average of 106mm /4.2 inches of rain. Four inches of rain during a month is by no stretch a significant amount of rainfall and this shows that St Lucia Weather in December is quite pleasant and you needn’t fear the rain.

Speaking of rainfall it is interesting to note that St Lucia weather in January features the next lowest rainfall, illustrating a consistency in rainfall pattern.

St Lucia December Weather Patterns

Ignoring all of this raw data for a moment it should be noted that the weather pattern remains relatively consistent throughout the year and December month is no exception. So you can expect beautiful blue skies and lots of sunshine with a few rain showers sprinkled in between.
So in December it is not unusual to have early morning showers followed by blazing blue skies, then some early afternoon showers preceding a radiantly golden sunset.
And if your vacation overlaps into January the St Lucia weather in January won’t be much different from your December weather.

A Word of Caution

When reviewing weather sites you will often see graphics indicating rain or notations saying things like 50% chance of thunder storms or other similar ominous information. Don’t be dismayed by all of this as you will find that the weather will be just fine no less than 95% of the time!
And guess what? … Whenever you don’t like the weather just have another drink and by the time you’re done it won’t really matter as the rain will either be over, or you really won’t care!

…Yes the drinks are that good!
