December: Summer Returns
December sees Guarita settle back into the summer pattern. The average swell eases to 1.5m (5ft), the period drops to 8.2s, and ideal wind sits at 32%. The wave energy is dominated by E and ENE, each around 22-23%, followed by ESE 17%, SE 13.6%, SSE 11.9%, and S 8.2%, with SSW and NW absent. This is classic trade-wind swell: fun, punchy, and usually small to moderate with occasional larger E/ENE pulses. While the surf can be grovelly, the winds are slightly better than spring: NE at 19.4%, ENE at 16%, NW/NNW at 6.7% combined, and morning land breezes are more reliable. Water temperatures jump to 22.1°C and air has a summer feel at 21.3°C, with 4.13mm/day of rain. For a board-shorts-and-rashguard session on the points and beach breaks, December still offers plenty of rippable 3-5ft (0.9-1.5m) waves.
