Conditions at Bridges in December
December: Winter Swell Engine Stirs
December delivers the clearest sign of winter at Bridges. Average swell height holds at 0.7m (2.3ft), but the period jumps to 6.8s, second only to January and February. The swell remains predominantly ESE (60.5%), with E (18.9%) and SE (8.6%) providing the rest. A touch of NNW energy (3.5%) also appears, offering occasional snapshots of what a true northwesterly groundswell could do at this west-facing break. Most waves are still in the 0.5-1m (1.6-3.3ft) range, but the 1-1.5m class is present at around 6-7%.
The trade winds are at their seasonal strongest. ENE is the dominant wind with 46.9%, followed by E at 19.9% and NE at 15.9%, and a notable chunk blows at 20-40kph. This is why the ideal-wind percentage falls to 31%: plenty of direction, but too much intensity for clean conditions. Still, when the wind eases in the mornings or a cold front clears the region, the west-facing break can serve up surprisingly crisp, punchy waves. Air temperature drops to 25.5°C, sea temperature to 27.3°C, and rainfall is lower at 2.37 mm/day, making December a solid starting point for the winter window.
