May: Windswell and Onshore Grind
May brings the first real lull. The average swell height eases to 3ft (0.9m) and the period shortens to 7.4s, so surf is small and often localised windswell. ENE and E swells account for 25.3 and 21.0 percent of the wave directions, with NE adding 18.4 percent; however, most of these swells are small, peaking in the 1ft to 3ft (0.3-1m) range. Offshore wind frequency drops to 19 percent, while ESE and E winds blow 16.3 and 14.8 percent of the time, setting up a persistent onshore push at this east-facing beach. Afternoon thunderstorms also ramp up with precipitation averaging 3.82 mm/day. Water temps are already 25.5°C, and the air averages 25.7°C. You can still catch fun, grovelly waves inside the reef on a longboard, especially in the mornings before the sea breeze wrecks it, but the quality window is narrow.
