December: Peak Swell, Peak Commitment
December is statistically the biggest month of the year for Antonio's, with average swell height peaking at 5-6ft (1.6m) and period solid at 10.0s. The North Atlantic low-pressure conveyor belt is operating at full capacity, generating waves from NE, NNE and ENE in significant amounts-43% NE, 24% NNE and 20% ENE-with the occasional true N/NNW pulse thrown in. But this month also has the lowest ideal wind percentage of the year at 33%, meaning offshore S/SW flow is a precious commodity. The strongest swells are frequently accompanied by NE winds that can take the edge off the quality. Still, when the pieces align-a N/NW groundswell and a subtle shift to southerly winds-Antonio's can hold some of the most powerful, well-shaped waves of the season. With water temp still comfortable at 27.3°C and air at 26.5°C, December is the month for the dedicated surfer to score.
