January: Winter Groundswell and Post-Frontal Cleanup
The North Atlantic winter machine delivers a consistent 4ft (1.2m) average swell with periods around 7.7s. NNE and NE swells lead the way at roughly 16% and 15%, with ENE close behind, meaning Jupiter's east-facing beach sees plenty of usable energy. The catch is wind: only 22% of January hours are ideal, and those come when a cold front passes and winds swing into the WSW-W-WNW-NW quadrant. That is exactly when the incoming NE/ENE swell gets groomed into clean, rippable 3-5ft (0.9-1.5m) waves. With air temps near 20.2°C and water still warm at 23.5°C, it is not tropics season, but it is very surfable. Rain is modest at 2.4mm/day.
