Conditions at Kilcummin in January
January: Midwinter Muscle
The turn of the year brings the North Atlantic to full attention. The average swell height is 1.9m (6ft) with a mean period of 12.7s, so the pulse is powerful and sits comfortably in the 10-14s long-period band. The wave rose is led by W (28.3 per cent) and WNW (21.6 per cent), while the NW sector adds 7.2 per cent and NNW a further 3.6 per cent, giving the preferred N-NNW-NW combination about 11 per cent of the spectrum. The swell-height distribution is stuffed with 1.5-2.5m (5-8ft) waves from the west and west-northwest, so there is no shortage of power. On the wind side, the S-SSW-SW offshore quadrant totals about 30 per cent and the ideal-wind figure comes in at 36 per cent; the true onshore northerly directions stay relatively rare, at around 10 per cent. That leaves plenty of clean-glass windows even in the middle of winter. Be prepared for cold: air averages 7.1°C, precipitation runs at 5.07mm/day, and the water temp is just 8.1°C. A hooded 5/4, boots and gloves are non-negotiable.
