May: Spring Warmth and the Fading Winter Pulse
May sees the winter machine switch off. The average swell height drops to 1.2m (4ft) and the average period slackens to 10.8s. The swell direction remains remarkably clean-over 96% from SSW through W, with WSW (40.1%) and W (33.5%) dominating-but the size falls dramatically: most of the energy sits in the 0.5 to 1m and 1 to 1.5m bins. These are fun, rippable conditions rather than powerful storm surf, ideal for bringing a groveler and reading the shifting sandbars.
Wind quality takes another step backward. Only 18% of the time is the wind ideal, as the WNW flow (31.0%) and W winds (12.1%) dominate through the day. Air temperature climbs to 10.5°C, water temperature is 11.7°C, and precipitation drops to 2.71mm per day. Surfing becomes less about raw power and more about finding the right tide and swell-angle windows along the beach.
