Conditions at Boca Barranca in September
September: Peak Rain, Minimal Waves
September is often the wettest month, and the surf statistics do little to offer redemption. Average height is 0.3m (1ft), average period is 14.2s, and the swell is almost entirely from the SSW (74.8%) with SW (11.8%) and S (11.5%) as sidekicks. The favourable W/WNW/NW/WSW sector is a tiny 1.5%, and there is no meaningful 0.5-1m energy-just traces from SSW (0.4%) and S (0.1%).
Offshore easterlies reach one of their seasonal peaks, with ENE/E/ESE/SE combining for about 24.0% of the wind rose, but ideal surf wind is 0% of the time. The bad westerly onshore quadrant totals 10.5%. Rain peaks at 7.37 mm/day, with air temps around 26.2°C and water temp at 29.2°C. It's a month to stay patient, watch the satellite, and save your energy for a rare window when a proper W/SW swell and offshore ENE breeze collide.
