May in Miami launches the start of the rainy season, with warm humid days ranging from 73°F to 87°F and afternoon thunderstorms becoming a near-daily ritual along South Beach and Biscayne Bay. Breathable resort-wear fabrics — moisture-wicking cotton, linen blends, quick-dry materials — are your best allies in the building heat and humidity. A compact umbrella or packable rain jacket earns its place in your bag for the roughly 11 days each month when the skies open up.

Based on typical May conditions in Miami. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
May in Miami signals the onset of truly hot and humid weather, ushering in the start of the rainy season. Expect daily temperatures to consistently soar, with daytime highs typically ranging from the upper 80s to low 90s Fahrenheit (around 30-33°C) and nighttime lows rarely dipping below the low to mid-70s Fahrenheit (22-24°C). Humidity levels are noticeably high, making the air feel thick and warm. Precipitation in May is characterized by frequent, often intense, but usually brief afternoon thunderstorms. These showers can arrive suddenly and clear just as quickly, so being prepared is key. For your wardrobe, prioritize lightweight, breathable fabrics like linen, cotton, and rayon. Loose-fitting clothing such as sundresses, shorts, tank tops, and airy shirts will be your best defense against the heat. Swimwear is essential, as are comfortable sandals or flip-flops for navigating the city and beaches. Always carry a compact umbrella or a light, packable rain jacket for those sudden downpours. Don't forget ample sun protection, including sunglasses, a wide-brimmed hat, and high-SPF sunscreen, as the Florida sun is incredibly strong.
A white sleeveless tank keeps things cool when temperatures peak, anchoring a look that earns its charm through a dusty blue wrap midi skirt. Raffia espadrilles and an ivory crochet bucket hat make it feel like a destination outfit.
