Jacksonville Beach • Surf Spot Statistics

Best Surf Season (November - February)

The North Atlantic switches on in November, and Jacksonville Beach starts to feed off the first real E/NE groundswells of the season. Cold fronts marching down from the continent and Nor'easters riding the Gulf Stream produce the most consistent winter window of the year. Average wave heights run 0.6-0.7m (2-2.3ft) with periods of 6.8-7.2s, and the ideal wind percentage reaches 16-19%, the best of any period. The key is the post-frontal wind shift to W/WNW/SW: it turns the beachbreak from a bumpy mess into a clean, rippable wall. When the NAO locks into a negative phase and the western Atlantic trough deepens, the size potential can push well beyond the averages into overhead-plus territory.

Fair Surf Season (March - April & October)

These are the transition months at Jacksonville Beach. March still carries winter-like energy-0.6m (2ft) at 7.0s-but the ideal wind percentage falls to 14% and afternoon seabreezes get more aggressive. April is a step down in size and power, with 0.5m (1.5ft) averages and a 6.5s period, though a late-season Nor'easter can still put a few 1-1.5m (3-5ft) lines in the water. October is the wild card: it ties with November for the highest average swell height at 0.7m (2.3ft), as tropical lows and early-season post-frontal swells cross the western Atlantic, but onshore NE/ENE winds dominate and the ideal wind percentage is only 10%. Wade through the bump and October can be excellent.

Low Surf Season (May - September)

From May through September, the Bermuda High takes over the subtropical Atlantic and Jacksonville Beach becomes a small-wave environment. Average swell heights tumble to 0.4-0.5m (1.3-1.5ft), periods shorten to 6.1-6.8s, and ideal surfing winds appear just 2-7% of the time. The swell rose is dominated by ESE and E windswell, while sea breezes and afternoon thunderstorms add daily roughness. Water temperatures climb to 28°C (82°F) and the lineup turns longboard-heavy. The one ace in the deck is tropical season: from August into September, a hurricane or major tropical low near the Florida coast can briefly turn the seasonal script upside down and serve up rare, firing, groundswell-quality surf.
