April: Clean Shoulder-Season Rippable Waves
April marks a step down in size but a step up in surfability. Average swell heights ease to 0.9m (3ft), periods drop to 9.0s, and the wave rose shows a higher percentage of small 0.5-1m swell. However, ideal offshore wind frequency ties for the year's best at 11%, and the offshore quadrant of N through ENE accounts for a season-high 17.6% of the wind distribution. That means April often delivers clean, lined-up 2-4ft (0.6-1.2m) conditions on the sandbars, especially during high-pressure spring weather. With water temperatures around 9.8°C and average air temperatures reaching 9.0°C, it is still cold, but the lighter winds and improving weather make it a prime month for logging groomed, user-friendly waves.
