May: The Summer Doldrums Take Hold
May is where the surf season levels off into the summer lull. Average swell height drops to 2.3ft (0.7m), with periods bottoming out around 5.9s, on the choppy, low-energy side of the spectrum. The wave rose is dominated by E (16.7%), ESE (19.3%), and SE (20.5%), almost all of it in the 0.5-1m range, with a growing share of under 0.5m micro-swell. The SSE-SW window is down to about 8.6%, and the SSW/SW directions are almost completely absent. Winds are ideal 17% of the time, but the dominant E/ESE trade flow is increasingly cross-shore and onshore, making it difficult for the south-facing beach to produce clean waves. Air temperatures are warm at 27.6°C, water temperature climbs to 28.1°C, and rainfall increases to 2.88 mm/day. This is groveler territory.
