Conditions at Hash Point in September
September: First Signs of Autumn Life
September is a quiet star of the shoulder season. Average height dips to 5ft (1.5m) - the lowest of the year on paper - but the average period jumps back to 10.1s, signalling the first recognizable groundswells of the new Atlantic season. The wave rose is still dominated by NNW (74.0%) and NW (19.0%), so Hash Point is not yet in its favourite window, but the longer-period western energy starts to make itself felt underneath the summer windswell. Ideal wind frequency is 46%, with the N/NNE quadrant beginning to mix with the fading NW flow. Water temp is 18.4°C, air temp averages 22.2°C (16.6-33.9°C), and rain is a scant 0.19mm/day. As the Azores High starts to lose grip, the first properly west-angled groundswells of the autumn are worth watching for.
