Conditions at The Cribbar in December

December: Full Winter Mode

December closes the year in full big-wave mode. The average swell height is 2.1m (around 7ft), period is a powerful 11.7s, and the Atlantic is in its most productive phase. The waverose shows W swell at 30.7%, with WSW adding 13.1%, WNW 10.4%, and NW/NNW adding another 7.2% - a beautifully broad west/northwest window that maximises the Cribbar's exposure. Heavy, long-period groundswell in the 2-2.5m (6-8ft) range is the most common winter currency, and the >2.5m (8ft+) category makes its strongest showing of the year. Ideal offshore winds blow 23% of the time, but westerly winds are also frequent, so you need to time the post-frontal transitions to catch clean conditions. With air temperatures averaging 8.7°C, precipitation at 4.15 mm/day, and water temperature down to 11.1°C, this is raw, wild, all-in winter surfing. December is when the Cribbar earns its legend - no reservations, just reef, swell, and cold.
