May: Small Swell and the Early Meltemi
May is small. Average swell height falls to 0.7m (2.3ft) and the period drops to 4.5s - right in the 'choppy, low, messy' category. The swell distribution becomes dominated by NNW at 39.4%, but almost all of it sits below 1m. True N/NE swell totals just 8.9%. On the wind side, the meltemi machine begins to spin up: NNW wind accounts for 36.9%, and N plus NNE adds another 10.3%. Yet offshore S-SW winds still total 24.3%, so there are windows for a rare clean, small day. With ideal wind only 5% of the time, May is more of a longboard month. Air temperatures are pleasant at 19.2°C (min 13.1°C, max 28.1°C), rainfall is low at 0.51mm/day, and the water temperature has climbed to 19.5°C. A 3/2 is your friend, and expectations should be kept in check.
