Conditions at Playa Blanca in May
May: Winter Swell Engine Switches On and Offshore Chances Peak
May is where Playa Blanca starts to get interesting. Average surf height holds at 5-6ft (1.7m), the period is 13.2s, and the swell mix is still overwhelmingly SW at 64% with WSW at 26%. Around 18% of waves are in the 6.5-8ft (2-2.5m) range, and the Southern Ocean is beginning to fire more regularly.
The key shift is wind: ideal wind conditions jump to 9%, the best percentage since the summer months. SSW flow is still the most common at 33%, and SW/WSW adds another 29%, but S wind at 13% signals more variability and a better chance of early-morning offshore pushes. When the NE/ENE/E/ESE wind lines up with the SW groundswell, Playa Blanca can produce clean, powerful waves in the 5-8ft range. Air temps cool to 15.6°C, water temp is 13.6°C, and precipitation rises slightly to 0.48mm/day.
