Conditions at Sealion Cove in May
May: Smaller Swell, Increasing Afternoon Chop
May sees the swell engine throttle down. Average heights fall to 1.7m (5.6ft) and period drops to 10.2s, with SW and WSW producing 27.5% and 22.7% of the energy respectively. W swell is only 8.7% and WNW 2.6%, so the cove's preferred direction is scarce. You're left with a lot of short- to medium-period south-west swell that can still wrap into the nooks and crannies.
Ideal offshore wind drops to 37%, and the WNW/NW sea breeze total jumps to over 22% - a sign of summer's onshore regime building. Air temps improve to 7.9°C, water temp to 8.3°C, and precipitation is the lowest of the year at 3.56mm/day. The surf is usually frothy and a bit soft, but fun if you pick a clean early tide and a fading swell.
