Based on typical May conditions in Jacksonville. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
Jacksonville's May is the Florida First Coast transitioning from the comfortable spring to the subtropical summer — 86°F afternoons, Gulf humidity building toward its summer peak, and the afternoon thunderstorm pattern that will define the weather through September beginning to establish itself. Jacksonville Beach, Ponte Vedra Beach, and the Timucuan Ecological Preserve's coastal trails are at their most pleasant before July's peak crowd and heat combination. The St. Johns River waterfront at Riverplace Boulevard and the San Marco neighborhood's restaurant scene operate fully outdoors in the warm May evenings. Jacksonville's coastal-casual Southern style embraces May's warmth — sundresses and shorts, lightweight cover-ups for the beach, and the relaxed confidence of a city built around outdoor coastal living. The afternoon thunderstorm timing (typically 3–6 p.m.) is predictable enough to structure beach days around; morning and evening outdoor time at Kathryn Abbey Hanna Park and the Timucuan Preserve is reliably clear and comfortable.

Frequently Asked Questions
What should I wear in Jacksonville in May?+
Light summer clothing handles Jacksonville's warm May afternoons. Sundresses, shorts, and breathable tops work for the 86°F weather at Jacksonville Beach and the St. Johns River waterfront. A compact rain poncho covers the afternoon thunderstorms that arrive most days around 3–6 p.m. Sandals handle the beach and waterfront walkways; a light wrap or cardigan manages the gap between outdoor warmth and air-conditioned restaurants.
Is May a good time to visit Jacksonville?+
May is an excellent month for Jacksonville — the beaches are warm but less crowded than June through August, the Timucuan Preserve's nature trails are accessible without the summer heat extreme, and the St. Johns River boat tours are in full spring season. The afternoon thunderstorm pattern is predictable enough to work around; morning beach time and evening waterfront dining are reliably clear.
What shoes are best for Jacksonville in May?+
Sandals handle Jacksonville Beach's sand and the St. Johns River waterfront's paved promenade. For the Timucuan Ecological Preserve's natural trail system and the Kathryn Abbey Hanna Park's wooded paths, a waterproof trail shoe or hiking sandal with grip provides better traction on the humid, root-covered natural surface. After afternoon thunderstorms, the San Marco neighborhood's brick streets can puddle at low points.
How warm does it get in Jacksonville in May?+
Afternoon highs average 86°F with lows near 65°F — warm and humid on the Florida First Coast. The Gulf humidity adds perceived warmth above the thermometer reading; 86°F at high humidity feels noticeably heavier than in drier cities. About 9 days bring rain, primarily afternoon convective thunderstorms. The Atlantic Ocean breeze at Jacksonville Beach moderates the heat on the beachfront.
What should I pack for Jacksonville in May?+
Pack light summer clothing, swimwear, sandals, a compact rain poncho, high-SPF broad-spectrum sunscreen, and a beach bag. A light cardigan handles air-conditioned indoor spaces. Insect repellent is useful for Timucuan Preserve trail visits, where the humid coastal ecosystem hosts mosquitoes in the vegetation.
