Conditions at Jupiter Inlet in December
December: Winter Consistency
December delivers the classic Jupiter combination: consistent size, more clean windows, and cooler air. Average swell is 4ft (1.2m) with 8.0s periods, driven by a mix of NE (21%), ENE (20%), NNE (14%), and E (13%) swells. The wind rose begins to look much friendlier: NNW (11%), NW (7%), and W/WNW combine for a solid offshore component, and ideal conditions reach 19%. Long-period groundswell from North Atlantic lows becomes more common, and after a front passes, Jupiter Inlet often separates itself from the rest of Florida. Air is cooler at 21.6°C, water is 24.7°C, and precipitation is low at 2.1mm/day.
