Conditions at San Juan in February
February: A Slight Nudge North, Still Marginal
February sees the same trade-wind machine, but the ENE component ticks up slightly and the average remains 3ft (0.9m) at 6.2s. East swell still leads the way (45%), with ESE close behind (42%), and now there are a few more days with 3-5ft (1-1.5m) waves - about 29% of the month. The direction remains too east for ideal shape on this NNE-facing coastline, but the slightly stronger ENE influence brings a touch more push and a better shoulder when things line up.
The wind table is a mirror of January: E (36%), ESE (21%) and ENE (19%) dominate, mostly in the 10-20kph range. With ideal winds only 23% of the time, the default is cross-shore roughness, but a passing cold front or upper-level low can flip winds to S/SW and produce sparkling pockets. Air stays at 24.9°C, water 26.3°C, and precipitation is a modest 2.26mm/day - if you find a clean day, it deserves respect.
