The best times to visit St. Kitts are March and April during the dry season when daytime temperatures reach the mid 80s Fahrenheit. September and October are the worst times because of a spike in rainfall during hurricane season.

January and February also are good times to visit because they are part of the dry season as well. But daytime temperatures are slightly cooler than March and April and are usually in the low 80s Fahrenheit.

Seawater temperatures may feel chilly for swimming, especially in the mornings. The average rainfall during the dry season is less than two inches a month.

St. Kitts and Nevis is a small, two-island country near St. Maarten and Antigua in the Lesser Antilles archipelago of the Caribbean.

It is a common port of call on eastern Caribbean cruises. It has five times as many cruise visitors as hotel and resort visitors, according to the Caribbean Tourism Organization.

Best Months for Temperatures

During the summer, temperatures rarely fall below 70 degrees Fahrenheit or 21 Celsius at night. They often climb above 85 degrees Fahrenheit or 29 Celsius and sometimes above 90 degrees Fahrenheit during the day, according to a regional report from the Curacao meteorological department.

The island’s high humidity is countered by trade winds that create a cooler atmosphere.

Like other Caribbean islands, winter falls between December and early March. Average daytime temperatures usually hover in the low 80s Fahrenheit.

Nighttime temperatures often drop into the low 70s during the winter. The chance of rain is low because winter is part of the dry season.

Worst Months for Rain

The rainy season in St. Kitts and Nevis hits between May and October. It is the hottest time of year with high temperatures sometimes reaching into the low to mid 90s Fahrenheit during the day.

St. Kitts is in the Atlantic and Caribbean hurricane belt. The highest risk for a tropical storm or hurricane in the Caribbean is in September followed by October.

This is the worst time of year to visit St. Kitts. Both months reach a low point in tourism because of the higher risk of rain. But hotel prices often decline as well.

High Season: Dry and Cooler

The most popular season of travel in St. Kitts is during the “winter” months, the period of December to March. However, the official high season often extends into April.

One major reason for this period being the high season is Carnival. Carnival begins on Christmas Eve and goes until early January. The festival is normally filled with parades, food festivals, street dancing, masquerades, private parties and more. It is the most popular time to visit St. Kitts for hotel and resort vacationers.

The peak in visitor arrivals means that hotel and resort rates are usually higher than other times of the year, and bookings are more difficult. For those looking to travel during this period, it is wise to make reservations well in advance. It’s also important to know that the increase in visitor traffic will lead to more crowds on beaches and island tours.

Low Season: June is for Events

One of the best times to visit St. Kitts and Nevis during the summer is June. Daytime temperatures reach the upper 80s Fahrenheit, rainfall averages a little more than three inches, attractions are less crowded and prices are reasonable.

Various festivals also take place during the low season. In May, St. Kitts has the annual St. Kitts Musical Festival. In June the island holds the St. Kitts and Nevis Regatta, a sailboat race.

One major travel disadvantage of travelling during the summer is that it is a recovery period for the island. Many businesses use this time of year to make renovations and undergo other in-house developments.
