Conditions at Playa Tivives in September
September: The Wettest, Most Wind-Swamped Month
September is peak rainy season along the Pacific coast of Costa Rica, and that shows up in both the weather and surf data. Average rainfall reaches 7.37mm/day, among the highest of the year, and air temps dip slightly to 26.2°C as extensive cloud and showers dominate. The swell still comes from the SSW/SW corner - SSW 74.8%, SW 11.8%, S 11.5% - with a long 14.2s period, but average height remains 1ft (0.3m) and 99.5% of observations are under 1.6ft (0.5m). Offshore winds are almost nonexistent at 7.1% total from N/NNE/NE/ENE, and the ideal-wind percentage is 0. The onshore flow is persistent and the surf quality is poor. September offers very little hope for wave quality at Playa Tivives unless a strong tropical disturbance aligns perfectly with a sizable SSW pulse and a rare offshore wind window.
