Understanding these fundamental aspects of San Juan's climate will help you prepare for your trip, ensuring you pack the right clothing and plan your activities accordingly. Knowing what to expect in terms of temperature, rainfall, and humidity will allow you to make the most of your visit, regardless of the time of year.

High temperatures typically reach the upper 80s°F (around 31°C), while the lows rarely dip below the low 70s°F (around 21°C). This stable temperature range means you can pack light clothing and enjoy the sunshine without worrying about extreme heat or cold. However, it's important to remember that humidity plays a significant role in how the temperature feels. The high humidity levels can make the air feel warmer than the actual temperature, so it's wise to stay hydrated and take breaks in shaded areas, especially during the hottest part of the day. Understanding the typical temperature range and the impact of humidity will help you plan your activities and ensure you stay comfortable throughout your stay in San Juan. Remember to check the daily forecast before heading out, but rest assured that you can generally expect warm and pleasant weather.
Rainfall
Rainfall is an important factor to consider when planning your trip to San Juan. As a tropical island, San Juan experiences varying levels of rainfall throughout the year. While it doesn't rain all the time, you should be prepared for occasional showers, especially during the wetter months. The rainiest months are typically from May to November, with the peak occurring in September and October. During these months, you can expect frequent and sometimes heavy showers, although they are usually brief and followed by sunshine. The drier months, from December to April, see significantly less rainfall, making them a popular time to visit. However, even during the dry season, you might encounter a passing shower, so it's always a good idea to pack a light rain jacket or umbrella. The amount of rainfall can also vary depending on the specific location within San Juan. Areas closer to the mountains tend to receive more rain than coastal areas. Understanding the rainfall patterns will help you plan your activities and pack appropriately. Don't let the possibility of rain deter you from visiting; the showers are often short-lived and can provide a refreshing break from the heat.
Humidity
One of the defining characteristics of San Juan, Puerto Rico weather is its high humidity. The tropical climate contributes to consistently high humidity levels throughout the year, often ranging from 70% to 90%. This high humidity can make the temperature feel warmer than it actually is, which is something to consider when planning your activities. The increased moisture in the air can also affect your comfort level, making it essential to stay hydrated and wear breathable clothing. While there isn't a specific "humidity season," the humidity tends to be more noticeable during the wetter months. When the air is already saturated with moisture, the added rainfall can make it feel even more humid. However, even during the drier months, the humidity remains relatively high. To cope with the humidity, it's advisable to wear lightweight, loose-fitting clothing made from natural fibers like cotton or linen. These materials allow your skin to breathe and help you stay cooler. Additionally, it's crucial to drink plenty of water throughout the day to stay hydrated and avoid heat exhaustion. Understanding and preparing for the high humidity levels will help you enjoy your time in San Juan more comfortably.
