Conditions at Rossnowlagh in February
February: Still Firing
February holds the intensity of January with an average swell height of 1.7m (around 5-6ft) and an identical average period of 12.6s. The WNW swell window is even more prominent, at 28.3% of all observations, with W at 22.1%, NW at 9.9%, and WSW at 7.8%. A large slice of that W/WNW energy falls into the 1.5-2.5m range, so the beach remains capable of overhead, grinding waves. The dominant wind directions are again from the southwest to west quadrant -- SW 11.0%, WSW 10.5%, S 9.7%, SSW 9.5% -- meaning there are plenty of blown-out days. Still, the 24% ideal-wind frequency means that when a high-pressure system settles in, offshore E/ESE winds can groom the long-period swell into clean, well-shaped lines. Water temperature drops to 8.3°C, air temps stay near 4.6°C, and rainfall at 3.9mm/day keeps the cliffs green and the rivers full.
