St Lucia Weather and Climate
St Lucia weather is mild year-round, typically ranging from the low or high 80’s Fahrenheit or high 20’s Celsius. The lowest temperatures are recorded in January, February and March, where it can get into the lower 70’s at night. The average temperature in St Lucia ranges from 22 to 30 degrees Celsius (72 to 86 degrees Fahrenheit) in the dry season, which lasts from December to May. Temperatures in St Lucia during the wet season are only slightly higher than those experienced during the dry season. The wet season lasts from June to November and temperatures vary between 23 to 30 degrees Celsius (74 to 86 degrees Fahrenheit). The trade winds and sea breezes tend to moderate the temperature and the cooling breezes provide refreshing relief during the hot days. However, even without the fairly constant island breeze, the highest temperature ever recorded was 89 Fahrenheit! The humidity averages around 70%, and it is a little more hot and humid from July to October, the rainy season. During the rainy season, you can expect showers throughout the day, and occasionally a few days of rain, if a system comes through. But quite often, throughout the year, you will experience just short showers followed by sunshine. The typical forecast for St Lucia is this: Sunny to partly cloudy with widely scattered showers; occasional heavy rain and thunderstorms with high gusts of wind. This covers everything and is kind of a running joke among locals. So we don’t pay much attention to the forecast, but instead look for signs in nature or just go with the flow. Unless it’s a hurricane, the worst that can happen is you get caught by a warm shower. Over the past years, St Lucia weather has of course been affected by climate change, the seasons and certain natural events that used to occur in a very regular pattern have become more difficult to predict. The driest months still tend to be March, April and May, but overall, there is less rainfall, and when it does rain, it rains very hard and floods more easily. The hurricane season spans between June and November, but St Lucia been directly hit in many years (not counting two smaller hurricanes, Dean in 2007 and Tomas in 2010). These did considerable damage, not so much from wind, but from rainfall and rough seas, causing flooding, coastal erosion, and landslides. Because the island is located so far south, most hurricanes veer off to the north before they can gather strength.

When to Travel
Peak holiday season for the Caribbean and St Lucia is from December to April. The Caribbean Island experiences an influx of foreign visitors and cruise ships during this period. December, January, February, March, April and early May are an ideal time to visit St Lucia as the daytime temperatures are not too high and this is the island’s dry season. During this time, you should make reservations well in advance. The months from June to November are off-season and some hotels and resorts close for renovations. While July, August, September and October can be quite hot and humid, a good time to travel is also during the so-called shoulder season, from mid April to mid June, and from beginning of November to mid December. During those times, the weather is still usually pleasant but there are fewer tourists and rates are lower.
