Conditions at Playa Madrono in September
September: Heavy Swell Meets the Roughest Wind Window
September is statistically the second-weakest month for surf quality at Playa Madrono. The swell side is almost too good: over 97 percent of the wave energy is from the SSW, with an average period of 13.5s. But the ideal wind percentage drops to just 37 percent, and WSW/SW winds combine for more than a third of all observations, frequently leaving the lineup lumpy and sectiony.
Rain totals an annual high of 11.60mm/day, air temperatures stay near 26.7°C, and the water temperature is 28.7°C. When a rare northerly or NNW pulse aligns with the SSW swell, there are still excellent 3-5ft (1-1.5m) waves to be had. But consistency is poor, so patience and a sharp eye on the wind charts are essential.
