Kicking off with puerto rico december weather, the island experiences a subtropical climate with mild temperatures and moderate rainfall during the month. The average high temperature ranges from 78°F to 82°F (25°C to 28°C), while the average low temperature falls between 68°F and 72°F (20°C to 22°C). The rainfall is evenly distributed throughout the month, with an average of 3.5 inches (89 mm) in the north and 2.5 inches (64 mm) in the south.
The Intertropical Convergence Zone (ITCZ) and the Northeast Trade Winds play a significant role in shaping Puerto Rico’s December weather patterns. The ITCZ brings warm, moist air from the equator, while the Northeast Trade Winds cool and dry the air. As a result, the island experiences a mix of sunny days and occasional rain showers throughout the month.
The Influence of El Niño and La Niña on Puerto Rico’s December Weather
As the festive season approaches, Puerto Rico’s residents eagerly anticipate the island’s winter weather patterns, which are significantly influenced by the El Niño-Southern Oscillation (ENSO). This complex Pacific Ocean-atmosphere phenomenon has a profound impact on the island’s climate and weather patterns, especially during the December months.
El Niño’s Impact on Puerto Rico’s Temperature and Precipitation
El Niño is characterized by warmer-than-average sea surface temperatures in the equatorial Pacific Ocean. This warming of the ocean water leads to changes in atmospheric circulation, resulting in drier and warmer conditions in Puerto Rico during December. According to the National Oceanic and Atmospheric Administration (NOAA), El Niño events tend to favor below-average precipitation and above-average temperatures in the island.
La Niña’s Impact on Puerto Rico’s Temperature and Precipitation, Puerto rico december weather
La Niña, on the other hand, is marked by cooler-than-average sea surface temperatures in the equatorial Pacific Ocean. As a result, Puerto Rico’s December weather tends to be wetter and cooler, with a higher likelihood of strong precipitation events. According to NOAA, La Niña events often result in above-average precipitation and below-average temperatures in the island.
Historical Data on El Niño and La Niña’s Impact on Puerto Rico’s December Weather
The following chart illustrates the historical data on El Niño and La Niña’s impact on Puerto Rico’s temperature and precipitation trends during December.
| Year | Temperature (°F) | Precipitation (in) | ENSO Phase |
| — | — | — | — |
| 1997 | 78.2 | 0.9 | El Niño |
| 1999 | 76.8 | 1.2 | El Niño |
| 2002 | 80.5 | 0.7 | La Niña |
| 2005 | 77.9 | 1.5 | La Niña |
| 2009 | 79.2 | 0.8 | El Niño |
| 2010 | 77.4 | 1.4 | La Niña |
Current Forecasting Predictions and Their Implications
According to NOAA’s Climate Prediction Center, a moderate El Niño event is forecasted to persist through the upcoming winter months, including December. This would likely result in drier and warmer conditions in Puerto Rico, with a below-average likelihood of strong precipitation events. However, the intensity and duration of this El Niño event are still uncertain, and continued monitoring is necessary to refine the forecast.
Storm Frequency and Intensity
While El Niño tends to suppress the frequency and intensity of tropical cyclones in Puerto Rico, La Niña events can lead to an increased risk of strong storms. However, the influence of ENSO on storm frequency and intensity is complex and can be influenced by other atmospheric and oceanic factors.
According to the NOAA Storm Prediction Center, the frequency and intensity of tropical cyclones in Puerto Rico are influenced by a combination of factors, including sea surface temperatures, atmospheric humidity, and wind shear.

The Impact of Puerto Rico’s December Weather on Human Health: Puerto Rico December Weather
Puerto Rico’s December weather may not be as chill as you think. While temperatures are generally pleasant, the tropical island still experiences heat waves, extreme humidity, and even intense rain showers. These conditions can take a toll on the human body, leading to various health-related issues that affect residents and visitors alike. So, what are the health implications of Puerto Rico’s December weather?
In Puerto Rico, December is often characterized by heat waves, especially towards the end of the month. Temperatures can soar to the mid-80s to low 90s Fahrenheit (29-32°C), leading to heat-related illnesses such as heat exhaustion and heat stroke. Prolonged exposure to the sun and heat can cause dehydration, electrolyte imbalance, and even organ damage. Heat-related illnesses are particularly concerning for vulnerable populations, including the elderly, young children, and people with pre-existing medical conditions.
Heat-Related Illnesses
Heat-related illnesses are a significant concern in Puerto Rico, especially during heat waves. The most common symptoms include:
- Dehydration: Feeling tired, dizzy, or experiencing headaches, fatigue, or nausea.
- Heat fatigue: Feeling weak or exhausted, often accompanied by nausea and vomiting.
- Heat stroke: A life-threatening condition characterized by a body temperature above 103°F (39.4°C), dry skin, and altered mental state.
It’s essential for residents and visitors to take precautions to prevent heat-related illnesses, such as staying hydrated, seeking shade, and avoiding strenuous activities during the hottest part of the day.
Respiratory Issues
Puerto Rico’s December weather also exacerbates respiratory issues, such as asthma and chronic obstructive pulmonary disease (COPD). The island’s tropical climate, combined with high humidity and pollution, makes it challenging for people with pre-existing respiratory conditions to breathe easily. In addition, December’s rain showers can trigger allergies and sinus issues, further complicating respiratory health.

The Role of Climate Change on Puerto Rico’s December Weather
Puerto Rico, an island nestled in the northeastern Caribbean, is facing a pressing challenge: climate change. As the planet warms, Puerto Rico’s December weather is not immune to the impacts of a rapidly changing climate. Rising temperatures, increased rainfall variability, and altered storm frequencies are just a few of the ways climate change is influencing the island’s weather patterns.
Climate change is influencing Puerto Rico’s December weather patterns in various ways:
Rising Temperatures
Blockquote: “Puerto Rico has warmed by about 1°C (1.8°F) since the early 20th century, with the largest warming trend occurring during the 1970s and 1980s.” (Source: IPCC 2021)
The increased temperature trend in Puerto Rico is evident in the island’s December average highs, which have risen from around 82°F (28°C) in the early 2000s to over 84°F (29°C) in recent years. This warming trend has significant implications for the island’s ecosystems, infrastructure, and human health.
Increased Rainfall Variability
As the climate changes, Puerto Rico is experiencing more extreme rainfall events. This increased rainfall variability can lead to flooding, landslides, and other hazards that put people and the environment at risk.
Table: Extreme rainfall events in Puerto Rico, 2000-2019 (Source: NCDC)
| Year | Number of Events | Average Precipitation (in) |
| — | — | — |
| 2000 | 5 | 3.5 |
| 2005 | 7 | 4.2 |
| 2010 | 3 | 2.8 |
| 2015 | 9 | 4.5 |
| 2019 | 11 | 5.2 |
The data shows a clear increase in extreme rainfall events, with an average precipitation of 4.5 inches (114 mm) in 2015, compared to 3.5 inches (89 mm) in 2000.
Altered Storm Frequencies
Puerto Rico’s hurricane season runs from June to November, but climate change is affecting the island’s storm patterns year-round. This includes the arrival of storms outside the traditional hurricane season, which can catch residents and authorities off guard.
- Storm frequency: Puerto Rico is experiencing more frequent storms, including hurricanes and tropical storms, due to the warming ocean temperatures and a more active hurricane season.
- Storm intensity: Climate change is also leading to more intense storms, with sustained winds and rainfall that can cause catastrophic damage and disrupt daily life.
- Storm duration: The duration of storms is also increasing, with some lasting for several days or even weeks, causing widespread power outages, property damage, and displacement.
- Storm season: The traditional hurricane season is shifting, with more storms arriving in December and January, when residents and businesses are least prepared.
Climate change is having far-reaching implications for Puerto Rico’s climate, weather, and ecosystems. Rising temperatures, increased rainfall variability, and altered storm frequencies are just a few of the ways the island is being affected. By understanding these changes, residents and policymakers can work together to build a more resilient and sustainable future for Puerto Rico.
