Conditions at El Muro in May
May: First Real Hints of Clean Surface
May is when El Muro starts to wake up. The average swell is around 6ft (1.7m), the period is 13.2 seconds, and the mix of SW (64.3%) and WSW (26.2%) swells delivers powerful, consistent groundswell. Nearly 14% of the total is in the 7-8ft (2-2.5m) band, so there are legitimate overhead-to-triple-overhead sets rolling down the line. The big change is wind: the ideal offshore/easterly window jumps to 5%, the highest yet, thanks to a slight increase in N, NE and E flow. The dominant SSW/SW winds are still a problem, but for the first time all year, the numbers suggest actual rideable windows.
Water temp drops to 13.7°C, average air temps fall to 15.6°C, and rainfall picks up to 0.48 mm/day. Winter is knocking on the door.
