December: Winter Patterns Lock In
December sees the winter surf machine fully engaged. The average swell height holds at 1.3m (4.3ft) with an 8.4s period. Swell direction is well distributed across the eastern quadrant - E at 19.9%, ENE at 17.8%, NE at 14.5%, and ESE at 11.6%. The favoured N-NE-E window still accounts for over 60% of the waves, giving Ponce Inlet consistent, rideable surf.
The wind improves too, with ideal offshore flow 39% of the time - a significant step up from October and November. Cold fronts moving across the Southeast often deliver W/SW offshores behind them, creating clean, lined-up conditions on the east-facing sandbars. Water temp drops to 21.4°C (70.5°F), so a 3/2 wetsuit becomes essential. With average air temperatures at 19.9°C (67.8°F) and low rainfall of 2.04mm/day, December often rewards those who are willing to brave the milder winter weather.
