Conditions at Sandy Beach in January
January: Midwinter Muscle
January is one of the heaviest months of the year at Sandy Beach. The average swell height comes in around 9-10ft (2.9m) with an average period of 11.8 seconds - a powerful, long-period pulse that puts the beach under a constant supply of storm swell. The directional spread favors the SSW through WSW window, with SSW (8.7%), SW (10.6%), and WSW (9.7%) dominating, plus a meaningful W component (4.2%). What truly separates January is the wind: ideal offshore flow from NNE through E blows 55 percent of the time, with ENE and E winds providing the bulk of the groomed conditions. Expect cold and raw surf - air temps average just 1.9°C and water temps hover around 5.9°C - but the reward is clean, powerful, sometimes XL waves on the better sandbar configurations.
