July in Miami is always a hot topic—literally! As locals and visitors gear up for the heart of summer, understanding what the weather brings can make or break your plans. Here’s a fresh look at Miami’s July weather for 2025, with all the details you need to stay cool (or at least prepared).
Sizzling Temperatures and Humidity
Miami in July is famous for its high temperatures and humidity. Daytime highs regularly reach 31°C to 32°C (about 88°F to 90°F), with some days even hotter. Nights offer little relief, with lows around 25°C (77°F). The air feels heavy, and the humidity is very high, making it feel even warmer. If you’re not used to this kind of heat, you might find it a bit overwhelming at first.
Sunshine and Rain: A Balancing Act
- Sunshine: Expect around 9 to 10 hours of sunshine per day. July is one of the sunniest months, but clouds can roll in quickly.
- Rainfall: Rain is frequent but usually comes in short, heavy bursts—mainly in the afternoon. On average, there are 16 days with some rain and about 119 to 145 mm of rainfall for the month. Thunderstorms are common, but they pass fast, so your beach day isn’t always ruined.
Sea and Outdoor Conditions
- Sea Temperature: The ocean is warm, averaging 29°C (84°F)—perfect for swimming or water sports.
- UV Index: The UV index is extreme, so sunscreen is a must.
- Humidity: It often stays above 70%, so light clothes and lots of water is recommended.
Storm Watch: Tropical Threats
July is the start of the hurricane season, and while full hurricanes are rare, tropical storms and scattered thunderstorms do happen. The middle of July sometimes brings a higher risk for tropical weather, so keep an eye on forecasts if you’re planning outdoor activities.
