Conditions at Porth Neigwl in November

November: Winter Is Setting In

November continues the autumn charge. Average swell is 7ft (2.1m) with a 10.5s period, so the beach is seeing regular, powerful Atlantic groundswell. W (18.3%) and WSW (12.7%) still dominate, with WNW (10.6%) and SW (6.7%) filling out the spectrum. The quality of the surf is again tied to the wind; ideal E/SE offshore flow only occurs 17% of the time, and strong WSW/SW onshore flow can quickly put the beach in a washing-machine state. Still, the reward is high - when the wind goes offshore, expect flawless, hollow walls. Water temp remains tolerable at 13.1°C, air averages 11.7°C, and precipitation climbs to 3.87mm/day. This is a month for flexible surfers who can pounce on the windows.
