Conditions at Red Tree Reef in May
May: Marginal Magic
May sees the winter swell switch fade. The average height drops to 5-6ft (1.5-1.8m), with the average period shortening to 10.2s. Swell direction remains stubbornly SW/WSW: combined, SW (27.5%), WSW (22.7%), and SSW (16.8%) make up nearly 67% of all observations, but most of that energy is in the 3-5ft (1-1.5m) range. The reef becomes a small-wave setup that needs a precise swell angle to produce anything memorable.
The wind regime turns increasingly summery. NW becomes the most frequent wind direction at 16.3%, which is onshore and bad for the west-facing lineup; ideal conditions drop to 26%, mostly early morning before the sea breeze pipes up. Water temp climbs to 8.1°C (47°F), and precipitation is near its yearly low at 3.84 mm/day. It's not a month for hero waves, but the dawn patrol can still find clean, rippable corners on the better SSW/SW pulses.
