Conditions at Playa de San Juan in June
June: Summer Windswell and Onshore Drone
June switches Playa de San Juan into summer windswell mode. The average swell height is down to 1.2m (4ft) and the average period is just 8.1s. Despite a plentiful north/north-east wave rose - N at 30.7%, NNE at 35.7% and NNW at 28.8% - most of that energy is short-period, locally wind-driven chop rather than organised groundswell.
The wind is almost always wrong. Ideal offshore flow occurs only 2% of the time, and the NNE/N quadrant combines for over 90% of the wind rose. N winds hit 26.7%, NNE 41.4% and NNW 22.8%, often in the 20-40kph range, producing lumpy, messy surf. The water warms to 20.0°C and air temps climb to 20.8°C, but for the surfer it is a season of dawn windows and micro-sessions.
