Conditions at Mullaghmore Head in March
March: Heavy, Then Slowly Mellowing
March remains squarely in the best season. Average swell is still a solid 5ft (1.5m), and the period holds at 11.9s - long-period and punchy. The dominant direction is WNW at 30%, with W (19%), NW (15%) and NNW (10%) filling out the window. This is the month when big late-winter lows still barrel across the North Atlantic, but the overall height distribution starts to shift lower: there is an almost equal spread between 1-1.5m and 1.5-2m bands, and only a small amount of XXL energy. Wind odds remain good, with S/SSW/SW totals around 26% and WSW adding 10%; ideal wind occurs 32 percent of the time. On the plus side, spring often brings more periods of high pressure between storms, offering glassy, sunnier windows than January's endless gray. Air temps are still cool at 7.2°C, water is 8.3°C, and rainfall eases slightly to 3.23mm/day, so keep the thick wetsuit handy.
