June: The Heart of the Swell Window
June is the furnace of the Central American surf season. The average swell holds at 4.5ft (1.4m), period at 13.8s, and the SSW/S/SW complex pours in 99.7% of all energy. SSW alone supplies 78.1% of the waves, with 53.6% at 3-5ft (1-1.5m) and 21.0% at 5-6.5ft (1.5-2m). This is proper, racking, long-period groundswell aimed straight at San Blas' SSW-facing beach, and the consistency is outstanding.
The wind picture improves nicely from the spring lull. Ideal surf wind climbs back to 53%, and the N/NNE/NE/ENE offshore quadrant is at 29.4%. Onshore S/SSW flow is 12.7%, but mostly light. Rain is the main issue - 7.08mm/day in the heart of the wet season - but tropical showers are often short. Air temps average 27.0°C and water temps sit at 30.1°C, so layers are unnecessary. Score an early-morning glassy window and you will find some of the strongest, most consistent surf of the year.
