Overview of Puerto Rico’s Geography and Climate: What’s The Weather Like In Puerto Rico In December
Puerto Rico is an island located in the northeastern Caribbean Sea, with a unique geography that plays a significant role in shaping its climate. The island is approximately 100 miles (160 km) long and 35 miles (56 km) wide, with a diverse landscape that includes mountains, forests, plains, and coastlines.
Puerto Rico’s central mountain range, known as the Cordillera Central, stretches for over 30 miles (48 km) and reaches elevations of up to 4,390 feet (1,338 meters) at Cerro de Punta, the island’s highest peak. This mountain range acts as a rain shadow, causing precipitation to decrease as you move away from the coast. The eastern part of the island, which is located in the trade wind belt, receives more rainfall and has a more humid climate.
Different Climatic Regions in Puerto Rico
Puerto Rico can be divided into several distinct climatic regions, each with its unique characteristics. The northwestern region, which includes the popular tourist destinations of Rincón and Aguadilla, has a dry tropical savanna climate. This region receives relatively low rainfall, with an average annual precipitation of around 30 inches (762 mm).
On the other hand, the eastern region, which includes the municipalities of Humacao and Naguabo, has a tropical monsoon climate. This region receives much higher rainfall, with an average annual precipitation of around 60 inches (1,524 mm). The southwestern region, which includes the municipalities of Ponce and Yauco, has a semi-arid climate, with low rainfall and high temperatures.
Climatic Comparison with Other Tropical Locations
When compared to other tropical locations in the Caribbean, Puerto Rico’s climate is unique in several ways. In terms of temperature, Puerto Rico’s average high temperature ranges from 78°F (25°C) in February to 88°F (31°C) in August, which is similar to other tropical locations in the region. However, the temperature variations between day and night are more pronounced in Puerto Rico due to its latitude.
In terms of humidity, Puerto Rico is relatively high, with an average relative humidity of around 80%. This is due to the island’s proximity to the tropical Atlantic Ocean and the trade wind belt. When it comes to precipitation, Puerto Rico receives an average of around 50 inches (1,270 mm) of rainfall per year, which is lower than some other Caribbean islands, such as Jamaica and Hispaniola.

While the sunshine is a major contributor to Puerto Rico’s pleasant climate, the cloud cover is also a significant factor in shaping the island’s weather.
Average Sunshine in December
Puerto Rico’s proximity to the equator and its location in the subtropics create conditions for a high level of sunshine throughout the year. In December, the island witnesses a relatively consistent amount of sunshine, averaging around 7-8 hours per day. This amount of sunshine is relatively high compared to other tropical locations, such as Hawaii, which receives around 6-7 hours of direct sunshine in December.
Cloud Cover Comparison
Compared to other tropical locations, Puerto Rico’s cloud cover is relatively high, particularly in the mornings and afternoons. This is due to the presence of a unique atmospheric phenomenon known as the trade wind inversion, which occurs when the northeast trade winds create a layer of cool, moist air near the surface. This layer of cool air is then capped by a layer of warm, dry air, resulting in the formation of clouds.
