Conditions at Dunmoran Strand in November
November: Heavy Water, Low Consistency
November brings true winter-scale surf back to Dunmoran Strand. The average swell height sits at 2.3m (7-8ft), and the average period is 11.6s, delivering powerful, long-period groundswell across the bay. The dominant swell directions are W (13.2%), WNW (15.6%), NW (9.6%) and NNW (9.9%), with WSW (6.3%) also in the mix. That means a lot of heavy Atlantic energy in the water each day; when the swell direction has enough north in it, the exposed sandbars can hold proper hollow waves. The main issue is wind consistency-ideal offshore flow from SSE/S/SSW/SW occurs only 26% of the time, and the same lows that generate the swell often ruin the surface with cross-shore and onshore winds. November is also one of the wettest months, averaging about 4.92 mm/day, while water temperature cools to 12.1°C. Chase the high-pressure windows and you'll find powerful, heaving winter surf.
