Delving into weather in PR in December, this overview provides a comprehensive understanding of the climatic conditions in the Caribbean region during the month of December.
The island’s tropical location contributes to a unique set of weather patterns in December, influenced by the North American High-Pressure System. The northern, southern, and eastern regions of the Caribbean exhibit notable differences in temperature, humidity, and wind patterns.
Understanding the Climatic Conditions of the Caribbean Region in December.
The Caribbean region is known for its tropical climate, characterized by high temperatures, high humidity, and abundant rainfall throughout the year. However, December marks the beginning of the dry season, which brings some relief from the intense heat and humidity of the previous months. The weather conditions in the Caribbean during December are influenced by the trade winds and the Intertropical Convergence Zone (ITCZ), a belt of low-pressure systems located near the equator.
Prevailing Weather Patterns in the Caribbean during December.
The prevailing weather patterns in the Caribbean during December are dominated by the trade winds, which bring dry, cool air from the northeast. This results in a decrease in temperature and humidity compared to the previous months. Additionally, the ITCZ shifts southward, allowing for more solar radiation to reach the region, leading to a slight increase in temperature.
Differences in Temperature, Humidity, and Wind Patterns among Regions.
The Caribbean region can be divided into three main areas: the northern Caribbean, the southern Caribbean, and the eastern Caribbean. Each area experiences distinct weather patterns due to its unique geography and location.
| Region | Average High Temperature | Average Low Temperature |
| —— | ———————— | ———————- |
| Northern Caribbean | 80°F (27°C) | 72°F (22°C) |
| Southern Caribbean | 82°F (28°C) | 73°F (23°C) |
| Eastern Caribbean | 84°F (29°C) | 75°F (24°C) |
The northern Caribbean, which includes areas such as Puerto Rico and the Dominican Republic, experiences a slightly cooler climate compared to the rest of the region. The southern Caribbean, which includes countries such as Venezuela and Trinidad and Tobago, tends to be warmer and more humid than the northern area. The eastern Caribbean, which includes islands such as Barbados and St. Lucia, experiences a more pronounced temperature gradient, with higher temperatures during the day and cooler temperatures at night.

Exploring the Impact of the North American High-Pressure System on Weather in the Caribbean.
During the month of December, the Caribbean region experiences a significant impact from the North American High-Pressure System (NAPHS). This large-scale weather phenomenon plays a crucial role in shaping the region’s weather patterns, and understanding its influence is essential for predicting and preparing for Caribbean weather conditions.
The NAPHS is a persistent high-pressure system that dominates the atmospheric pressure field over North America during the winter months, including December. This high-pressure system creates a clockwise flow of air around it, which can lead to various weather effects in the Caribbean region. The NAPHS can influence the region’s weather patterns by altering the position and strength of the Intertropical Convergence Zone (ITCZ), a belt of low-pressure systems near the equator that drives the Caribbean’s weather.
Potential Effects on Precipitation
When the NAPHS is present, it typically leads to a decrease in precipitation in the Caribbean region. The high-pressure system can suppress the development of low-pressure systems that are responsible for precipitation. However, this does not mean that no precipitation occurs when the NAPHS is present. Instead, precipitation can be confined to isolated areas, where the high-pressure system is weaker or where low-level moisture is more abundant. For example, during December, the island of Puerto Rico can experience heavy rainfall due to its location in the path of low-pressure systems that are influenced by the NAPHS.
Potential Effects on Wind Direction
The NAPHS can also impact the wind direction in the Caribbean region. During December, the high-pressure system typically leads to a northwesterly wind direction, which can result in cooler temperatures and a decrease in humidity. This wind direction can vary depending on the location within the Caribbean and the strength of the high-pressure system. For instance, the northern Caribbean islands, such as the Bahamas and the Turks and Caicos Islands, are more likely to experience a stronger northwesterly wind direction than the southern Caribbean islands.
Potential Effects on Temperature
The NAPHS can also influence the temperature in the Caribbean region during December. The high-pressure system can lead to cooler temperatures, particularly during the night, due to the advection of cooler air from the north. The temperature range can vary depending on the location within the Caribbean and the strength of the high-pressure system. For example, the island of Jamaica can experience temperatures ranging from 70°F (21°C) to 85°F (29°C) during December, while the island of Barbados can experience temperatures ranging from 75°F (24°C) to 85°F (29°C).

Wind roses are a crucial tool in understanding the prevailing weather conditions in any region, and Puerto Rico is no exception. In the context of December weather in PR, wind roses provide essential information about wind speed and direction, temperature, and their relationship.
Wind roses are graphical representations of wind data, often used in meteorology to illustrate the direction and speed of wind. In the case of Puerto Rico, wind roses for December reveal the prevailing wind direction and speed, which is crucial in understanding the microclimates and regional differences in temperature.
Wind Speed and Direction in December PR
Wind speed and direction are the two primary components that define a wind rose. The diagram is usually divided into quadrants, each representing a specific wind direction. The size and color of each quadrant indicate the wind speed, with larger sections indicating stronger winds. According to data from the National Weather Service, in December, the prevailing wind direction in PR is northeast, with wind speeds ranging from 7-15 km/h (4-9 mph).
The wind roses also reveal temperature patterns in December. Typically, the coldest months in PR are December, January, and February, while July is usually the warmest. Wind roses help understand how temperature is influenced by wind direction and speed. It is essential to note that temperature is not directly represented in wind roses, but rather through the relationship between wind direction, wind speed, and resulting air masses.
Examples of Wind Roses in PR December
The following is a simplified illustration of a wind rose diagram for Puerto Rico in December:
| Wind Direction | Wind Speed (km/h) |
