Conditions at Doughmore in December
December: Prime Time on the Wild Atlantic
December is prime time. Average swell height is 2.3m (7-8ft), period is 12.2s, and the Atlantic low-pressure train is firing regularly. The swell direction is near-perfect: W (24%), WSW (15%), WNW (12%) and SW (5%) together define Doughmore's ideal window. The >2.5m (8ft+) category occupies a larger slice of the W and WSW distributions, meaning serious XL days are on the table.
Winds are mostly onshore from the SW-W quadrant, with that unfavorable combo 38% of the time; offshore NE-ESE windows arrive 22% of the time. Water temps bottom out around 10.2°C, air averages 7.5°C, and winter storms bring 4.6mm/day of rain. If you score a day with a fresh E/ESE wind and a long-period W swell, Doughmore is one of the heaviest, most challenging beach breaks on the west coast of Ireland. Bring your big-wave board.
