Conditions at Beliche in September
September: Autumnal Shift
September is the bridge from summer slop to autumn gold. Average swell heights are still modest at 5ft (1.5m), but the period jumps to 10.4s, giving the waves a longer, more organized push. The wave rose remains NW-heavy, with NW 47.1%, NNW 25.5% and WNW 14.3%, yet the first hints of S/SW and WSW energy appear as early extratropical lows start to wander farther south. Crucially, ideal N/NE offshore winds jump back up to 33 percent of the time, offering the best consistency since winter. Water temperature peaks around 19.3°C, air temperature averages 21.0°C, and rain is still light at 0.75mm/day. September can produce clean, warm-water surf at Beliche, especially when a modest S or SW swell graces the coast.
