Conditions at Portrush in November
November: Grit and Groundswell
November is raw and serious. Average swell reaches 6-7ft (1.8-2.1m) with a period of 10.3s, and the swell rose shows a broad spread of W at 16.9%, WNW at 17.9%, WSW at 8.2% and NW at 7.3%. Portrush is a magnet for mid-Atlantic lows now, but the wind remains the weak link: ideal offshore wind sits at just 9%. South through WSW winds account for the largest share of observations, and frequent frontal passages mean changeable, blustery conditions. The surfer who stays flexible can still find dawn patrol windows with punchy, long-period lines and the last of autumn's mild weather.
Air temperatures fall to 7.2°C, water drops to 11.1°C, and precipitation is at its highest at 3.93 mm/day. November rewards the committed.
