The climate of Jamaica
The island of Jamaica has a tropical savannah climate or a savannah climate with many sunny days. However, there is a reasonable chance of (very heavy) rainstorms or thunderstorms. During the day temperatures are around 24-25 degrees Celsius on average. During the winter Jamaica has a dry period with at least 1 month with less than 60 millimeters of precipitation (long time record). According to the Köppen climate classification this is an Aw-climate. Jamaica officially knows no tropical climate (Af-climate). However, we think there are some places inland and along the south coast that show signs of this type of classification.

Nice weather
Jamaica’s best weather can be enjoyed during the dry period that lasts from January to April. The sun shines exuberantly during most days. However, sometimes rain may fall. During this time of year the weather is at best. Jamaica is very popular as a winter sun destination. The winter period also is very popular to get married in Jamaica or for a romantic honeymoon.

Rainy season?
During the wet period chances of rain are higher. There also is a reasonable chance of completely gray, wet and windy days. However, Jamaica doesn’t really have a real rainy season with rain for days on end. Most of the rain falls during the months of May-June and September-November. The amount of precipitation depends on the location and the altitude you are in. Especially in the higher regions in the eastern part of the island large amounts of rain can fall. Most of the hotels and resorts are situated in the western part of the island. Here you can find the famous beautiful beaches as well.


Wind

A trade wind almost continuously comes from the north east. Along the north coast this has a cooling effect. The south coast usually experiences less wind because of the blocking effect of the mountains on the island.

Hurricanes
Jamaica is located in an area with a reasonably high hurricane activity. During the hurricane season that lasts from June to November the island has a fair chance of getting hit by hurricanes or tropical storms. Chances are highest during the months of September and October. However, most of the hurricanes that hit Jamaica have lost strength because they usually hit another island first. Over land hurricanes lose most of their strength. Because Jamaica is close to the main land hurricanes get too little time to build up in strength over water.

More climate information
Climate figures are very useful but don’t present a general impression of the climate and the eventual weather circumstances within a certain period. The figures don’t always reflect the chance of wintry weather, extreme heat or hurricanes. That is why we monthly offer useful extra climate information.
