Count on St. Lucia weather in October to be just about as wet as anyplace else in the Caribbean.

October is the second riskiest month of the year for weather after September. High amounts of rain fall throughout the region thanks to the annual Caribbean hurricane season.

St. Lucia is not spared. In fact, rain historically is slightly higher in October than September, which is unlike many other destinations that get hit more in September.

If there is any consolation, the total rainfall isn’t as bad as many other popular tourism locations.

October Rainfall

Total rainfall in St. Lucia has averaged five inches during October over the course of more than 30 years, according to statistics from St. Lucia Meteorological Services.

That total is not nearly as bad as the eight to 10 inches often reached in places such as Cancun, Cozumel and Dominica during October.

But it is quite a bit worse than the best months to visit St. Lucia for weather. They are February through April, when rainfall averages a little more than one inch a month.

Another fact to consider when planning a vacation to St. Lucia or any other Caribbean island is the average number of days each month that have rain. The higher the average, the higher the risk of bad weather.

St. Lucia has an average of 20 to 21 days of rain every month from July through November, which clearly marks the rainy season for the island.

Even though the island has less total rain than many destinations, it ranks at the top for the total number of days with rain during the month.

St. Lucia Temperatures in October

The average high temperature in St. Lucia during October is 87 degrees Fahrenheit or nearly 31 Celsius, according to statistics from St. Lucia Meteorological Services. The average low is 77 degrees Fahrenheit or 25 Celsius, which occurs mainly at night.

One of the best reasons to go is lower prices for hotels and resorts as a result of low demand. It’s a good time to go for budget-conscious travelers.

Another reason is that shrewd and experienced travelers will take a last-minute trip if the seven- to 10-day forecast shows a period of good weather.

Should Anyone Go in October?

October is the riskiest month to visit St. Lucia because of the high risk of rainfall, especially for anyone who plans a vacation well in advance.

On the other hand, October may be a great month to go for budget and last-minute travelers because of the possibility of low prices and a rare break in the forecast.
