Long-run averages for May
Is May Right for You?
Weigh the advantages and considerations before booking
- + May delivers your final window before Florida's brutal summer humidity takes hold. Warm, mostly sunny days prevail. The sea breeze still carries some bite, near the bayfront.
- + You get the best of both worlds. Shoulder-season pricing on accommodations holds steady before the summer vacation rush peaks. Most seasonal attractions already run at full tilt. The Saturday Morning Market hums with activity. Drum circles gather nightly at North Shore Park.
- + Gulf of Mexico water temperatures climb to 78-80°F (26-27°C). Good for swimming. No winter shock. No August bathtub warmth.
- + Banyan trees and live oaks wear their full, lush canopy now. Bougainvillea and hibiscus explode in color. A walk down Beach Drive turns photogenic. The Pinellas Trail rewards cyclists with saturated greens and blooms.
- − The trade-off arrives with afternoon thunderstorm patterns. These are not all-day rains. They are reliable. Brief, intense downpours roll in off the Gulf around 3 or 4 PM. Central Avenue floods for twenty minutes. Then they vanish.
- − Peak season has passed. Yet crowds remain substantial. Lingering snowbirds overlap with early summer vacationers. The Dali Museum draws lines. Sunken Gardens fill up. Weekends see the worst of it.
- − The May sun here is no joke. UV index hits 10, the maximum rating. You will feel it by 10 AM. This light fades fabric fast. Locals duck under downtown bar awnings by midday.
