February: Consistent Winter Groundswell With a Stormy Edge
February sustains the winter pulse, posting a 3.5ft (1.1m) average swell height and a 12.4s period. The swell is still W-dominated at 53.2%, with WSW 32.5% and SW an additional 9.0%; that puts the bulk of energy in the Trestles sweet spot, especially once it wraps into the point. The dominant wave heights are 2-3ft (0.5-1m) and 3-5ft (1-1.5m), with enough 5-6ft (1.5-2m) readings during stormier windows to give Lowers some punch. Ideal offshore wind drops to 46%, still strong, but the onshore influence is growing: S, SSW, SW and WSW now make up about 28% of the wind distribution. This is February's classic battle between winter storms and lingering high-pressure offshore flow. At 2.90 mm/day, it is the wettest month of the year, and precipitation tends to come with the same systems that generate W/WSW swell. Water temperature is 14.2°C and air averages 13.3°C. Catch the windows between fronts and February delivers some of the heaviest, most powerful Trestles waves on the books.
