Conditions at Rossnowlagh in November
November: Prime-Time Power
November is full-on winter at Rossnowlagh. Average swell height is up to 1.5m (around 5ft) and average period strengthens to 11.6s, setting the stage for powerful Atlantic groundswell. The swell direction table is dominated by WNW at 29.2% and W at 20.0%, with NW at 15.4% and NNW at 11.4%. Large waves are becoming common: both W and WNW show significant percentages in the 1.5-2m and 2-2.5m classes, with the occasional bomb over 2.5m. Unsurprisingly, wind remains the enemy: SW, WSW, S, and SSW directions dominate, and the ideal-wind share is just 25%. November rewards surfers who are willing to wait for the cold front to pass and the wind to swing into the offshore eastern quadrant. Water temps have cooled to 11.7°C, air temps average 6.9°C, and a wet 4.6mm/day is part of the deal.
