Things to Do in Caribbean Islands


The climate and weather averages for Aruba are relatively mild and moderate, with average monthly temperatures in the low 80s. The islands enjoy the trade winds from the east and north, contributing to its year-round pleasant climate. Wind speeds range from seven to 25 miles per hour but rarely go above 28. The average wind speed in June is 25 mph, and in November it’s 18 mph. Even though the trade winds are moderate, they can cause serious sunburns, so bring sunscreen!


The climate and weather averages in Bonaire are based on the monthly rainfall average. This data is rounded off to the nearest inch. Despite the dry, tropical climate, Bonaire experiences several months of high humidity. In general, the island experiences above-average relative humidity levels throughout the year. The least humid month is March, with a humidity level of 69%, while the wettest month is November, with a humidity level of 74%.


The weather in Curacao is mild and sunny throughout the year. Due to the constant trade winds blowing from the east, the island is often pleasantly cool. There are no significant rainy seasons in Curacao and daytime temperatures range between 78 and 88 degrees Fahrenheit. The best time to visit the island is late December through mid-March when temperatures are at their lowest. Precipitation is minimal, with most occurring during the winter.

Puerto Rico

Despite being located on a large body of water, Puerto Rico experiences seasonal variations in temperature. July was the warmest month, while temperatures were slightly below average in other months. However, temperatures in February and May were much more pleasant. In addition, Puerto Rico has a mild climate, with average temperatures of around 70 degrees. Here, we’ll look at the average climate and weather for Puerto Rico. We’ll also look at the average wind speed.

The Leeward Islands

The climate and weather in The Leeward Islands are tropical, with summers that are much wetter than the winters. Generally speaking, the average temperature in The Leeward Islands is around 26.1°C (78.9°F). The average annual rainfall on these islands is 763 mm, or about 30 inches. The driest month is February, while the warmest month is October. Temperatures are typically slightly cooler in March.


To learn more about the weather in Barbados, it helps to know its climate and rainfall averages. For this island, the clearest month is January. There are no cloudy days on average during this time of year, with an average of 53% clear skies. In addition, the warmest days are September and October, with a peak probability of 32% for both months. The percentage of rainy days varies throughout the year, from about half a day in February to more than half a day in June.


The climate in Grenada is tropical. The island is cooled by northeast trade winds. Temperatures vary greatly according to altitude, with a high of 86 degrees Fahrenheit in the summer and a low of 75 during the winter. Daytime temperatures are usually warm to hot, with a wide range from 77 to 86 degrees in the winter. Trade winds are present from November through February, ensuring that temperatures are comfortable year-round.

Weather in the Caribbean

The Caribbean enjoys a warm tropical climate throughout the year, with average high temperatures reaching around 28degC (82degF). The driest months are December through March and April, and the rainiest months are July and November. Although rain is likely, it is usually accompanied by short, heavy showers. Sunshine hours remain relatively constant throughout the year. While June to November is hurricane season, the Caribbean does also experience tropical storms.

Tropical monsoon climate

A tropical monsoon climate is a humid and warm climate with a seasonal pattern. Rainfall peaks and troughs are intense and often occur in the same month. Monthly mean temperatures are consistently above 18degC. There is a dry season, but this period is less intense and less frequent than the other seasons. The Caribbean has a tropical monsoon climate, as do many other islands in the world.

This type of climate occurs mainly along coastal margins and larger areas of Asia and Southeast Asia. During winter, the region experiences a Siberian high and a thermal low in the ocean. Monthly average temperatures always exceed 18oC. During the dry season, rainfall is scarce and often infrequent. The Caribbean experiences a distinct dry season in late spring. The climate is mild and temperate throughout the year.

Dry season

The Caribbean’s dry season runs from mid-December to mid-April. This time of year is particularly popular for holidaymakers. In contrast, the U.S. Northeast, Midwest, and Canada experience winter weather, and the Caribbean’s dry season is drier than in the U.S. Northeast. Because of this, hotel prices and availability are usually higher during the winter months. Travel during this time to the Caribbean should be planned well in advance.

The climate of the Caribbean is tropical with one or two distinct seasons. The Caribbean is typically warm year-round, with a long rainy season lasting from May to October, and a dry season lasting from December to March. Rainfall amounts vary from place to place, with a higher proportion of rainfall falling on windward-facing islands. During this time, tropical revolving storms (CRs) can produce rainfall amounts greater than climatological dry season monthly mean rainfall.

Hurricane season

As we gear up for another hurricane season in the Atlantic, the Caribbean is already facing its own set of challenges. While this volcano’s eruption has been delayed in the past, the current outlook indicates that the region will likely experience more hurricanes than normal this season.

The official hurricane season in the Caribbean is from 1 June to 30 November. However, hurricane activity tends to be most intense in mid-August to early October. While these are high-risk periods, you can still enjoy a sunny beach vacation at any time of year. The Caribbean is located in the Atlantic Ocean hurricane belt, which stretches from the Gulf of Mexico, the Atlantic Ocean, and the Caribbean Sea. While hurricane activity peaks between mid-August and late October, the worst months tend to be April and May. Trans-Atlantic cruises are normally not affected by hurricane activity.

Average monthly rainfall

The West Caribbean experiences significant seasonal variation in average monthly rainfall. In October, the region receives 4.0 inches of rain, while January only receives 0.4 inches of precipitation. The rainfall averages across the West Caribbean are calculated from the 25th to 75th percentile bands. In the eastern Caribbean, however, the rainy season lasts only 4.6 months and October is considered one of the driest months. The Caribbean has wetter seasons and drier seasons, so the average rainfall is usually higher in those regions.

In the Caribbean, rains vary greatly from island to island. Mountainous areas receive more rain than lowland islands, which have a generally flat climate. A mountainous island like Martinique, for instance, receives six times as much rainfall as Presqu’ile de la Caravelle, which has a much lower average monthly rainfall. Mount Pelee, a volcano in Martinique’s center, is a significant influence on the islands’ rainfall, especially on the northern beaches. The north coast of Martinique is covered in grey sand, while the southern beaches have a white coat of sand.

Best time to visit

If you’re considering a trip to the Caribbean, spring is the perfect time to plan your vacation. While summer months are usually the most expensive, you’ll find that many parts of the Caribbean are much cheaper. It’s also important to consider the weather – hurricanes rarely strike the Caribbean before September. Most of the islands are relatively quiet during the spring and summer months, making them great choices for vacations. Avoid the most popular tourist destinations – St Lucia and Antigua – but don’t let this stop you from exploring the region’s beauty.

The Caribbean’s dry season lasts from November to May. While the winter months are often the busiest, May and June are great times to travel because they’re outside of the rainy season. You’ll also find prices are cheaper, and the weather is less rainy. Although rain is possible during these months, you’ll likely have plenty of sunshine. So, if you’re planning a vacation in the Caribbean during one of these months, you’ll be sure to have a great time!
