Conditions at Mullaghmore Head in April
April: Spring Transition and North Swells
April marks the first real step away from winter. Average swell drops to 3-4ft (1.1m) and period falls to 10.7s - still powerful enough to keep Mullaghmore interesting, but nowhere near the XL days of December through March. Swell direction remains strongly north-westerly: WNW (30%), NW (18%), NNW (18%) and W (16%). Notice the north-northwest component becomes more common as spring high-latitude blocking produces more N/NNW swell - good for exposing the reef, though heights are smaller. The tradeoff is wind. April's wind rose is more mixed; NNW winds jump to 10%, while north/northeast winds total near 15%. That pushes ideal wind down to 29 percent. Still, when a low pressure system stalls west of Ireland and sends a solid NW groundswell with S/SW flow, you can score clean, rippable waves without the brutal winter chill: air averages 8.6°C, water 9.7°C, and rain drops to 2.78mm/day.
