Conditions at Porth Neigwl in October
October: The Engine Fires Up
October is the real turning point. Average swell jumps to 6ft (1.9m) with the period climbing back to 10.1s, and there is a noticeable increase in W (21.9%), WSW (17.2%) and SW (10.0%) energy. The storm track is cranking again, and Porth Neigwl's west-northwest exposure snaps to attention as repeated frontal systems deliver solid groundswell. Better still, ideal offshore wind is at 20%, roughly the same as September, so there are more legitimately good days than in summer. The combination of autumn swells and E/SE offshore flow on the back side of low pressure is money. Air temps cool to 13.7°C, water to 14.8°C, and rain starts ramping back up at 3.32mm/day. A 4/3 hooded suit is the usual call.
