Conditions at Playa Guiones in September
September: Maximum Swell, Maximum Caution
September is the rawest month of the year. The swell direction is almost perfect-66.7% SSW, 28.8% SW and 2.3% WSW-which puts 98% of the energy in the optimal quadrant. Heights are still solid at 1.5m (5ft) on average, with the highest percentage of swell in the 1.5-2.5m (5-8ft) range of any month, and periods remain a powerful 13.1s. The problem is wind: only 40% of the month is ideal, and S/SW/WSW onshore flow accounts for a substantial share of observations. Heavy green-season rain at 8.75mm/day and tropical convection add lump and bump, making late afternoon sessions blown out. Your best chances are in the early morning, when the land breeze fights the onshore flow and long, lined-up SSW/SW swells are still holding their shape. Air sits at 26.7°C and water temp is 28.8°C.
