Conditions at Sennen Cove in November
November: Winter Swell Machine
November is deep winter in all but name, and Sennen sees average swell heights of 7ft (2.1m) with a 10.5s period. The W/WSW/SW swells continue to dominate - W 18.3%, WSW 12.7%, WNW 10.6% - but there's also an increasing chance of NW and NNW swell, which aligns beautifully with the beach's northwest exposure. The trade-off is wind; ideal offshore conditions drop to 9% of the time as frequent low pressure systems drag westerly and northwesterly gales across Cornwall. When a high-pressure ridge builds between fronts, though, the combo of long-period W/NW swell and offshore S/SW winds is electric. Water temps fall to 13.1°C, air to 11.7°C, and precipitation rises to 3.87 mm/day - expect changeable, stormy autumn days and some absolute all-time sessions.
