September: Big Rain, Rising Southwest Swell, and the Transitional Pulse
September is the beginning of the upswing for Playa Avellanes, even though it falls in the low season. The swell average remains 5ft (1.5m), period is 13.1s, and the big story is SW jumping to 28.8 percent while SSW still leads at 66.7 percent. The ideal west quadrant totals 31.1 percent, the best west-window showing since June, and there are real opportunities for firing 5-6.5ft (1.5-2m) sets from SSW and SW combined.
This is the wettest and most unstable wind month of the year. Rain averages 8.75mm/day, ideal wind drops to 50 percent, and the wind rose spreads across all directions: SE at 8.4 percent, S at 7.8 percent, NE at 6.5 percent, SW at 7.0 percent, and WSW at 6.6 percent all hover nearby.
