When you think of Jamaica and weather, think paradise, because that’s the only way to truly describe it. No one here needs bulky winter coats or mittens to go about their day, even in the height of winter. Year-round, shorts, sleeveless shirts, and sundresses are still the go-to fashions for tourists and locals alike.

The next thing about weather in Jamaica is that it also doesn’t get too hot. The weather dictates lightweight clothing that you can wear any time of the year.

When planning your trip to Jamaica, or anywhere in the world, it’s important to keep the weather and climate in mind. Here’s what you need to know:

Understanding Jamaica's Weather & Climate

Jamaica is located north of the equator at about 18°N and °77W, south of the island of Cuba, and is surrounded by the Caribbean Sea. jamaica weather

Trade Winds

The island’s climate is highly influenced by the North-East Trade Winds. These are the same winds that help ships sail around the world. They are also the driving force for hurricanes and storms, which are pretty common in Caribbean Islands like Jamaica.

During the winter months, these winds, called ‘Northers’, blow onshore from North America, causing temperature drops from December to March.


Jamaica has a tropical marine climate. This means the island’s climate is strongly influenced by the sea.

Trade winds pick up moisture from the warm seas surrounding the island which rises as they approach mountainous barriers and falls as relief rainfall. Sea temperatures in Jamaica range are always warm, even in the winter months, and don’t typically fall below 78.8°F (26°C).

Topography and Vegetation

Despite these factors, some Caribbean islands experience higher temperatures throughout the year than Jamaica. The reason for this is topography, along with vegetation, which also has a huge influence on the climate. jamaica weather

Jamaica is a mountainous country, of which ⅓ is covered in lush vegetation. For every 100 meters or 300ft, temperatures fall by about 1°F. Variations in elevation result in cooler temperatures, particularly in places like the Blue Mountain region which spans the eastern parishes of the island, and the Mandeville region on the island’s south coast.

Understanding Weather Patterns in the Caribbean

Jamaica’s tropical marine climate means conditions are well balanced throughout the year. There are no temperature extremes as there are with other types of climates, and there are no prolonged periods of wetness or dryness.

Does it Stay Warm All Year in Jamaica?

Pretty much. Jamaica does not experience snowy winters like other places in the world, and the temperature doesn’t drop by much. Jamaica weather can get a little chilly now and then, but the most you’ll need is a light sweater to keep the gentle winds off.

When is the Rainy Season in Jamaica?

Though the Caribbean's hurricane season happens from June 1st to November 30th each year, the rainiest months in Jamaica are October and May every year. jamaica weather

Jamaica experiences an average of about 70 inches (1800 mm) of rainfall per year. In the South Coast, convectional rainfall is most common. Rainfall is heaviest on the island’s North Coast due to relief rainfall. So, in the mountainous regions, this average will increase to about 134 inches (3,400 mm) per year.

The infamous Blue Mountains can see average rainfall exceeding 200 inches (5000 mm) with its rainshadow effect leaving the nation’s capital city, Kingston, on the windward side with significantly less, about 28 inches (710 mm).

What is the Best Time to Visit Jamaica for Good Weather?

Ironically, the best time to visit Jamaica is during the drier months from December to April.

The reason for this is that this lies directly outside of the hurricane season. The hurricane season in Jamaica can ruin your trip, as the destruction from hurricanes can be unpredictable, and you’d hate to be stuck with no power and access to the amenities you’ve come to rely on.

But this is no hard and fast rule. There is ample warning before any storms or hurricanes hit the island, so this is nothing to worry about unless you’re planning a trip that will last more than a few weeks.

Plus, unlike other tropical destinations, Jamaica does not experience entire days of rain. If it falls in the morning, your afternoon is likely free. Most times, however, rainfall occurs in the afternoon and into the night, so plan your activities around the weather forecast. Jamaica for Weather
