April: First Real Clean Windows
April is where the seasonal flip really takes hold. The average swell height is 1.1m (3.5ft), the average period has stretched to 8.6s, and ideal wind scores jump to 52 percent. The swell rose remains east-heavy, E at 36.0% and ESE at 33.7%, with SE adding 16.8% for plenty of 2-4ft (0.6-1.2m) surf. More importantly, the wind data shows a strong southerly influence: S (18.8%), SSE (18.9%), and SSW (8.3%) begin replacing the summer's persistent NE/ENE flow. Water temperatures are still pleasant at 24.7°C, air temps average 23.1°C, and rainfall drops to 2.97 mm/day. This month rewards surfers who pick the days: when a SW/W change arrives, The Alley gets cleaner, more lined-up waves with a fraction of the summer chop.
