Jupiter Inlet offers surfable conditions year-round, but the best windows for quality waves are typically during the fall and winter months, from October through March. During this period, the swell activity is more consistent, with a higher percentage of ground and wind swells compared to summer. October and November stand out as the peak months, featuring the largest mean swell size (0.9m–1.0m) and a solid mix of ground (16–17%) and wind swells (64–69%), providing better wave energy. Wind conditions, while still predominantly onshore (bad winds 85–88%), see slight improvements in favorable wind days (12–15%). Winter months like December and January also deliver decent swells, though slightly smaller (0.8m), with similar wind challenges. Spring (March–April) sees moderate swell activity, but summer (June–August) is the least favorable, with minimal ground swells, weak wind swells, and very poor wind conditions (95–98% onshore). If you’re aiming for the most rideable days, prioritize late fall and early winter when swell consistency, size, and marginally better wind odds align. Summer is mostly flat or blown out, while spring offers occasional opportunities but lacks the punch of the colder months.
