Caribbean Weather Patterns in December

December marks the beginning of the dry season in the Caribbean, bringing with it a relatively calm and sunny atmosphere. However, there are still some weather patterns that are worth noting during this time.
During December, the Caribbean is dominated by high-pressure systems, particularly over the subtropical ridges of the Atlantic and Pacific Oceans. These high-pressure systems bring fair weather, with clear skies and gentle winds. In the northern Caribbean, particularly over the Greater Antilles (Cuba, Hispaniola, Jamaica, and Puerto Rico), the trade winds typically prevail, influencing the local climate and weather patterns.
A low-pressure system known as the “African Easterly Jet” plays a significant role in shaping the weather in the Caribbean during December. This jet stream carries warm, moist air from the African continent into the North Atlantic, resulting in increased precipitation and unstable weather conditions over the region.
Historically, climate scientists have used satellite data, atmospheric pressure patterns, and ocean currents to predict and understand the weather patterns in the Caribbean during December. The National Oceanic and Atmospheric Administration (NOAA) and other international meteorological agencies rely on climate models, observational data, and satellite imagery to forecast the weather in the Caribbean. By analyzing historical trends, climate scientists can identify patterns and anomalies in the weather, allowing them to provide more accurate predictions and warnings to the public.
Weather Patterns and Wind Directions
The trade winds and prevailing westerlies in the northern Caribbean are characterized by gentle breezes and stable atmospheric conditions. However, there are instances when the winds can become gusty or change direction significantly, particularly when tropical waves or low-pressure systems are present in the region. For instance, a tropical wave in the Caribbean during December 2020 led to heavy rainfall and strong winds in the Greater Antilles.
Temperature Fluctuations, Weather in december in the caribbean
During December, the average temperature ranges from 77°F (25°C) in the northern Caribbean to 85°F (29°C) in the southern Caribbean. While temperature fluctuations are generally minimal during this time, there can be instances of cooler or warmer temperatures depending on the prevailing weather pattern. For example, a cold front in the winter of 2013-2014 led to a significant drop in temperature in the Greater Antilles.
Historical Climate Trends
Climate trends in the Caribbean during December can be linked to larger-scale climate patterns, such as the El Niño-Southern Oscillation (ENSO).

These downpours can lead to flash flooding, landslides, and other natural hazards, posing a significant risk to human life and infrastructure.
Sunshine Patterns in the Caribbean in December
While December is known for increased rainfall and precipitation, the Caribbean still experiences relatively long days, with an average of 10 hours of direct sunshine. This allows for pleasant outdoor activities, such as snorkeling, diving, and sailing, making December a popular time for travelers and tourists.
Flooding and Landslides in the Caribbean in December
The heavy rainfall and flash flooding associated with tropical depressions and heavy downpours can lead to devastating flooding and landslides. In 2004, a severe hurricane season affected several Caribbean islands, resulting in widespread flooding and landslides that claimed numerous lives and caused significant damage to infrastructure.
Case Study: Effects of Heavy Rainfall on Agriculture
In 2010, heavy rainfall and flooding affected large areas of cropland in several Caribbean island nations, including Haiti and the Dominican Republic. The resulting crop damage and loss were estimated at millions of dollars, affecting the livelihoods of many farmers and families reliant on agriculture.
Storm Activity in the Atlantic and Caribbean in December

December is one of the quieter months for storm activity in the Atlantic and Caribbean, but it’s still crucial for the region to be prepared for any potential hurricane or tropical storm that may develop. The Atlantic hurricane season officially ends in November, but storms can still occur in December, although they are rare.
Months with the Highest and Lowest Risk of Tropical Storms and Hurricanes in the Atlantic and Caribbean
The Atlantic hurricane season has distinct periods of high and low activity. According to the National Hurricane Center (NHC), the months with the highest risk of tropical storms and hurricanes in the Atlantic are August, September, and October. These months account for the majority of tropical cyclone activity in the Atlantic due to the combination of warm ocean waters and atmospheric conditions that favor storm development.
On the other hand, December is considered one of the months with the lowest risk of tropical storms and hurricanes in the Atlantic and Caribbean. Historically, December has seen an average of only 2-3 named storms, with most of them being weak.
- The NHC reports that the Atlantic has averaged 12 named storms, 7 hurricanes, and 3 major hurricanes per season since 1966. While December is typically quiet, it’s essential for residents and visitors to remain vigilant and stay informed about weather conditions.
- December’s average sea surface temperature (SST) in the Atlantic is around 22-23°C (72-73°F), which is cooler than the peak months of August and September. This cooler SST contributes to the reduced storm activity during December.
