Conditions at Revolcadero in May

May: Maximum Period and the Most Consistent Size

May is the peak of the long-period spring/summer transition. Average swell height rises to around 4.5ft (1.3m), the average period hits the annual high of 14.2s, and SSW reaches its yearly peak in dominance at 91.8%. It is an incredible directional setup for Revolcadero, and the height distribution follows: around 68% of waves are 3-5ft (1-1.5m), and nearly 24% are 5-8ft (1.5-2.5m), including the first meaningful 6-8ft (2-2.5m) stragglers from stronger southern pulses.

Wind is the trade-off. Ideal conditions drop to 40%, with afternoon W and WSW flow dominating the wind rose (W 24.5%, WSW 22.6%). Rain begins to increase to 1.40mm/day, air temperatures average 27.1°C, and water temperature jumps to 29.1°C. To really enjoy May you need to be in the water early, when the overnight offshore breeze leaves the surface clean and the big-period south swell is breaking with authority.
