St. Lucia Weather in September

St. Lucia weather in September is almost the worst of the year. It’s enough to keep away both cruise ships and resort visitors.

Tourism for St. Lucia drops to the lowest point of the year, according to the Caribbean Tourism Organization.

But the weather doesn’t keep everyone away. Some brave souls do visit the island’s resorts, especially for last-minute vacations if the weather forecast looks good. Some cruise ships also visit the island. They just shouldn’t expect great weather.

September Rainfall


St. Lucia has average rainfall of eight inches during the month, according to the St. Lucia Meteorological Service. It is the second highest amount of the year, just barely behind slightly more than eight inches in October.

By comparison, the island averages about two inches during the dry season from February through April.

It rains an average of 20 days during the month, equal to July, August, October and November. It rains only 12 days during April, which is the fewest of the year.


September Temperatures


Daytime temperatures in September reach the highest point of the year with an average of more than 87 degrees Fahrenheit or 31 Celsius, the island’s meteorological service says.

Nighttime temperatures stay warm as well with an average of 77 degrees Fahrenheit or 25 Celsius.

Swimmers should find water temperatures comfortable during all times of the day.

Temperatures during the spring dry season are only about two degrees cooler.

Travel planners should think carefully about St. Lucia’s weather in September and whether it makes sense to go there during the month.

Luck plays a big part in weather conditions, but historical averages offer enough information to expect a higher than normal risk of rain.

Anyone who wants to visit St. Lucia will find that April is a better choice for a combination of warm temperatures and low risk of rain.
