Humidity Levels by Region and City

North Florida

North Florida experiences varying levels of humidity throughout the year. Cities such as Jacksonville and Tallahassee tend to have higher humidity levels compared to other regions in the state. This is due to their proximity to the Gulf of Mexico and the Atlantic Ocean, which contribute to the moisture in the air.

During the summer months, humidity levels can reach as high as 90% in some areas. However, during the winter months, the humidity tends to drop, making the climate more comfortable for residents and visitors alike.

Central Florida

Central Florida, including cities like Orlando and Tampa, experiences a subtropical climate with moderate humidity levels. The proximity to both the Gulf of Mexico and the Atlantic Ocean influences the humidity levels in this region as well.

While summer months can be hot and humid, with humidity levels around 80%, the winters bring a relief with lower humidity levels. Central Florida is known for its pleasant weather during the winter months, making it a popular destination for snowbirds seeking to escape the colder climates up north.

South Florida

South Florida, including Miami and Key West, is known for its tropical climate and high humidity levels. The region is surrounded by water, with the Atlantic Ocean to the east and the Gulf of Mexico to the west, creating a humid environment throughout the year.

Humidity levels in South Florida can often exceed 80% and even reach 90% during the summer months. The combination of high humidity and high temperatures can make it feel quite hot and sticky. However, the region also benefits from cool ocean breezes, which can provide some relief from the humidity.

It’s important to note that these are generalizations and humidity levels can vary from year to year and even within different parts of each region. Local weather patterns, rainfall, and proximity to bodies of water all play a role in determining the specific humidity levels in each city.

For more accurate and up-to-date information on humidity levels in specific cities, it is recommended to consult local weather forecasts or websites such as www.weather.com.

What Causes Florida’s High Humidity?

Florida is well-known for its high levels of humidity throughout the year. The state’s unique geography and climate contribute to this phenomenon. Here are some factors that cause Florida’s high humidity:

1. Proximity to Water

Florida is surrounded by water on three sides, with the Atlantic Ocean to the east and the Gulf of Mexico to the west. This close proximity to large bodies of water greatly influences the humidity levels in the state.

As water evaporates, it adds moisture to the air, resulting in higher humidity levels.

2. Warm Temperatures

Florida’s warm climate plays a significant role in its high humidity. The state experiences long, hot summers with temperatures often reaching into the 90s Fahrenheit. Warmer air can hold more moisture, leading to higher humidity levels.

3. Sea Breezes

Florida’s coastal regions are often affected by sea breezes. During the day, the land heats up faster than the ocean, causing air to rise over the land and draw in cooler air from the sea. As the warm air rises, it cools and condenses, resulting in increased humidity levels.

4. Rainfall

Florida receives a significant amount of rainfall throughout the year, particularly during the summer months. Rainfall contributes to humidity by adding moisture to the air. The combination of frequent rain showers and high temperatures creates a humid environment in the state.

It is important to note that humidity levels can vary throughout the state of Florida. Coastal areas and regions near large bodies of water tend to have higher humidity levels compared to inland areas. Additionally, humidity levels can vary by season, with summers typically being the most humid.

Tips for Dealing with Florida Humidity

Stay Hydrated

Florida’s high humidity levels can cause excessive sweating and increase the risk of dehydration. It is important to drink plenty of water throughout the day to stay hydrated. Carry a water bottle with you and sip on it regularly, especially if you are spending time outdoors or engaging in physical activities.

Staying hydrated not only helps regulate body temperature but also supports overall well-being.

Dress Appropriately

When it comes to dressing for Florida’s humidity, lightweight and breathable fabrics are your best friends. Opt for loose-fitting clothes made from natural fibers such as cotton or linen. These materials allow air to flow freely and help to wick away moisture from your skin, keeping you cool and comfortable.

Don’t forget to wear a wide-brimmed hat and sunglasses to protect yourself from the sun’s rays.

Use Air Conditioning

Air conditioning is a lifesaver in Florida’s hot and humid climate. Make sure your home, office, or car has a functioning air conditioning system. Set the temperature to a comfortable level and allow the air conditioner to circulate cool air.

If you don’t have access to air conditioning, consider spending time in public places such as libraries, shopping malls, or movie theaters that are air-conditioned.

Use Dehumidifiers

Dehumidifiers can be extremely helpful in reducing the humidity levels in your home. These devices remove excess moisture from the air, making the environment more comfortable and less prone to mold and mildew growth.

Place dehumidifiers in areas that are particularly humid, such as basements or bathrooms, to maintain a drier atmosphere. Regularly empty and clean the dehumidifier to ensure its optimal performance.

Avoid Strenuous Outdoor Activities

Engaging in strenuous outdoor activities during the peak hours of Florida’s humidity can be challenging and potentially dangerous. The combination of high heat and humidity can lead to heat-related illnesses such as heat exhaustion or heat stroke.

If you must be outdoors, try to schedule your activities during the cooler parts of the day, such as early morning or late evening. Take frequent breaks, seek shade, and listen to your body’s signals.


To summarize, while Florida experiences humid conditions year-round, humidity levels fluctuate by month and region. On average, the hottest, most humid time of year runs from June through September. The winter months see slightly lower humidity levels. However, even northern Florida cities stay quite humid compared to most of the country. Understanding Florida’s humid climate can help you plan activities and stay comfortable no matter when you visit or live in the Sunshine State.
