Conditions at Playa Nosara in August
August: Consistent South Swell, Slightly Windier Windows
August continues the Southern Hemisphere swell machine. Average height remains 1.5m, the period is still a long 13.3 seconds, and SSW/SW energy takes up over 92% of the wave rose. The 1.5-2m class holds strong at 28.4%, making the average day in August a genuine head-high-plus surf with plenty of punch.
Where August loses a step is the wind. Ideal conditions occur 52% of the time, down from July's 64%. The northeast trades are weak at 8.7%, but there are more SE and SSE flow events - nearly 17% - that can put a bit of wobble on the face. Still, winds rarely exceed 20kph, so the quality remains high, especially in the mornings. The lack of strong onshore wind, combined with focused SSW/SW groundswell, makes August a reliable surf month.
Rainfall is substantial at 6.36mm/day and water temperature sits at 29.1°C. With solid south swell running and no major hurricane activity near the spot, August delivers consistent size and rideable conditions. Just pick your break along the beach carefully to match the tide and shifting sandbars.
