Why is Florida hot? Causes and heat countermeasures

Florida in the southeastern United States is known for its warm climate year-round, with especially hot and humid summers that many people find oppressively muggy. Below is a detailed explanation of why Florida gets hot, how to deal with the heat, and some cooler spots within the state.

1. Reasons Why Florida Is Hot

1-1. Tropical and Subtropical Climate

• Northern Florida has a subtropical climate, while southern Florida is tropical, resulting in high temperatures and humidity throughout the year.
• Average summer high temperatures range from 30°C to 35°C (86°F to 95°F), with high humidity making it feel even hotter.

1-2. Moist Air from the Atlantic Ocean and Gulf of Mexico

• Surrounded by water, Florida constantly receives warm, moist air from the Atlantic Ocean and Gulf of Mexico, increasing humidity.
• The high humidity intensifies the muggy feeling and causes the heat index (felt temperature) to be higher than the actual air temperature.

1-3. Long Daylight Hours and Strong Sunlight

• During summer, Florida experiences long daylight hours and a high sun angle, resulting in strong and prolonged sunlight exposure.

1-4. Urban Heat Island Effect

• Cities like Miami and Orlando retain heat in asphalt and buildings, making it difficult for temperatures to drop at night.

2. Heat Countermeasures

2-1. Individual Level

• Avoid strong sunlight during the day, especially between 11 a.m. and 4 p.m.
• Frequently hydrate and replenish salts.
• Wear breathable light clothing, hats, sunglasses, and use sunscreen.
• Use air conditioning indoors and seek shade or cooler places when outdoors.

2-2. Housing and Buildings

• Use blackout curtains or blinds to block direct sunlight and prevent indoor temperature rise.
• Efficiently use air conditioning combined with fans to enhance cooling.
• Open windows at night when cooler air is available.

2-3. Community and Administration

• Establish and utilize cooling centers.
• Issue heat wave and heatstroke warnings promptly and provide quick information.
• Support vulnerable groups such as elderly people, children, and those at health risk.

3. Cooler Spots (Places to Escape the Heat)

3-1. Coastal Beach Resorts

• Coastal areas like Miami Beach and Key West benefit from sea breezes that improve airflow and reduce the muggy feeling.
• Activities such as swimming and water play help lower the perceived temperature.

3-2. Lakes and Rivers in the State

• Water areas such as Lake Okeechobee and the St. Johns River offer cooler breezes, making them good places to beat the heat.

3-3. Northern Florida

• Areas around Jacksonville and Pensacola in northern Florida are somewhat cooler and less humid than southern parts.
