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 is when the city transitions from its glittering dry-season peak to the lush, steamy intensity of summer — humidity climbs noticeably, the afternoon sky turns dramatic shades of grey before releasing torrential rain, and the iconic Art Deco Historic District on Ocean Drive becomes an obstacle course of puddles by 4 p.m. Temperatures stay warm through the entire month, with lows in the low 70s even overnight, which means lightweight fabrics aren't optional — they're survival. Visitors planning to explore Wynwood Walls, Lincoln Road, or the mangrove trails at Oleta River State Park will need to plan around the afternoon storm window — mornings are typically clear and beautiful, but by 2–3 p.m. the Atlantic sea breeze collides with inland heat and produces powerful thunderstorms that can last an hour before clearing. Dress in quick-dry fabrics, accept that your shoes may get wet, and embrace the breezy, layered resort-wear aesthetic Miami does so well.

Packing List
What to Pack for Miami in May →
Light resort-wear is perfect for Miami in May: linen or cotton sundresses, lightweight linen trousers with a sleeveless blouse, or a breezy co-ord set. Moisture-wicking fabrics handle the humidity better than pure cotton, which can feel heavy when wet. Bring a light wrap for heavily air-conditioned restaurants and hotel lobbies, which often feel arctic compared to the heat outside.
May is an excellent time to visit Miami if you want lower hotel rates and thinner crowds than peak winter/spring season. The beaches and cultural scene are fully active, the weather is warm and beautiful in the mornings, and summer's most extreme heat hasn't fully arrived yet. Just plan outdoor activities for the morning and early afternoon and be indoors or under cover by 3–4 p.m. for the daily storm.
Comfortable sandals or waterproof slides are ideal — streets flood quickly during afternoon thunderstorms, so avoid suede or unprotected leather. On South Beach and the Bayside Boardwalk, flip-flops or casual sandals are standard. For Wynwood or dinner out in the Design District, strappy heeled sandals work well on dry mornings and evenings.
Miami in May averages lows around 73°F and highs near 87°F, with high humidity making it feel closer to 95°F in the afternoon sun. Rain arrives almost every day toward late afternoon — about 11 days per month see significant precipitation. Nights stay warm in the low 70s, so there's no need for heavy evening layers.
Pack lightweight sundresses, linen trousers, moisture-wicking tops, and a compact umbrella or packable rain jacket. Sunscreen SPF 50 and UV sunglasses are essential for beach days. Include quick-dry footwear, a light wrap for air conditioning, and a small crossbody bag that can handle a splash. Leave heavy denim and thick knits at home — they won't be comfortable.
