January: Summer Swell Meets the Trade Winds
January is a tale of abundant swell energy fighting a messy wind regime. Average wave heights hold around 5ft (1.6m), but the average period is a rather mediocre 8.9s, so most of the energy is short-period windswell and local sea. The swell rose is dominated by the E/ESE/SE/SSE window, with about 75% of all incoming energy lying in the ideal directions for Ansteys. The largest slice comes from the E at 22.8%, followed by the ESE at 18.7%. Most waves are in the 3-6ft (1-2m) range, but the S direction provides a few 6-8ft (2-2.5m) pulses that can light up the sandbanks.
The wind is the real problem. NE flow dominates at 26%, SSW at 16.7%, and NNE at 12.5%, leaving only 18% ideal surfing windows. Onshore flow from E/ESE/SE/SSE adds up to just under 15%, enough to regularly texture the ocean. With air temperatures near 24.5°C, water temperature at 25.3°C, and 3.42mm/day of rainfall, this is classic tropical summer weather. Wait for a southward-moving coastal low to drag winds into the W/NW quadrant before putting in a dawn patrol session.
