Best and Worst Times to Visit St. Lucia
The best time to visit St. Lucia depends quite a bit on avoiding the annual hurricane season and learning about the average monthly weather.
The rolling green island of St. Lucia has the benefit of being warm every month of the year because it is one of the most southern islands in the Caribbean. But winter months have cooler seawater, while fall months have more rain.
The island is a popular stop on eastern Caribbean cruises because it lies conveniently close to other cruise destinations such as Dominica and Barbados.
Adding to its attraction are a beautiful harbor, excellent beaches and interesting natural attractions such as the volcanic Piton Mountains. (Bathing in volcanic mud is a unique excursion on the island.)
Best Months to Go for Good Weather
Travel planners should look at the average St. Lucia weather by month to find the best and worst times to visit the island. The most popular months aren't always the best months.
March is the most popular month to visit St. Lucia, according to the Caribbean Tourism Organization. But the best month to visit St. Lucia for good weather is April because of less rain and warmer temperatures.
After March and April, the next best choices are May followed by February. May has slightly more rain than February. But it’s also three degrees warmer, which makes a difference in comfort while swimming in the ocean.
December is the second most popular month to visit St. Lucia. January and February are popular as well. Northerners come to the Caribbean to get away from snow and cold. They also have time off around the Christmas holiday.
St. Lucia in winter also has the lowest temperatures of the year. Even though daytime temperatures reach into the 80s Fahrenheit, water temperatures will feel cool at times from northern currents and trade winds. Some days the seawater may feel too chilly for swimming at all.

St. Lucia Hurricane Season
The worst months to visit St. Lucia are September, October and November.
Tourism statistics show that people clearly avoid St. Lucia in September because of heavy rains. They also should avoid October and November because the average weather during those months is just as bad as September.
Rainfall hits St. Lucia hard during those months because of the Caribbean hurricane season, which officially begins June 1 and ends Nov. 30. September is the peak of activity for the hurricane season in most of the Caribbean because of tropical storms and hurricanes.
Bad weather in most of the Caribbean lessens in October and even more in November. But the St. Lucia hurricane season is slightly different.
Historical weather data from the St. Lucia Meteorological Services shows that September and October both deliver an average of eight inches of rain to St. Lucia.
November is only a little less with an average of seven inches, followed by July and August with six inches.
In contrast, St. Lucia's annual weather has a dry season with an average of about two inches of rain that falls from February through April and just under three inches in January and May.
The island has rain about 20 days each month from July through November but only 12 days in April.
Average Monthly Temperatures
St. Lucia has some of the most consistent temperatures in the Caribbean. The average high ranges from 84 degrees Fahrenheit or 29 Celsius in January and February to 87 degrees or 31 Celsius from May through October.
The average lows, mainly at night, range from 74 degrees Fahrenheit or 23 Celsius in January to 77 degrees Fahrenheit or 25 Celsius from May through October.
Seawater temperatures are usually about midway between the daily highs and nightly lows. But strong trade winds and currents from the north will make the seawater feel colder at times and possibly uncomfortable.
Tourism Statistics: Popular Times to Go
The chart above shows recent tourism statistics for the island using data provided by the Caribbean Tourism Organization.
It clearly shows that the most popular months of the year to visit St. Lucia are March followed by December.
March is one of the peak months to visit the Caribbean for families with children on spring break from school or college. December is popular for many parts of the region because it is a chance to get away from the first month of winter in the north.
July and August show a jump in visits again because of families with children out of school. January and February continue the pattern of getting away from winters that started in December.
Again, March is a popular time to visit St. Lucia, but April is the best month to visit for a combination of warm temperatures and low risk of rain.
Going in September Despite Risky Weather
It is no surprise that the least popular month of the year -- the one with the fewest crowds and lowest prices -- is September. That month is the least popular time of the year to visit almost any part of the Caribbean because of bad weather from the annual hurricane season.
Still, some people visit the Caribbean and St. Lucia in September either because:
They have no other time of the year to visit;
They don’t know the weather is risky;
They go on last-minute vacations after seeing good weather forecasts.
The third group above will take advantage of low prices in September and go then. If possible, they will look at the 10-day weather forecast to find out if any bad weather is developing. If it isn’t, they will book last-minute trips and potentially save money on cruises or resorts.
