Conditions at Magheroarty in May
May: Spring Shoulders
May marks the arrival of the fair season proper. Average swell height eases to 5.9ft (1.8m), and the period drops to 9.7s - a step down in raw power but still rideable and punchy. The swell rose is still beautifully aligned with the coast: WNW 17.6%, W 15.5%, NNW 12.4%, NW 11.2% and N 2.3%. That combination is excellent for surf quality, but the wave heights are increasingly in the 0.5-1.5m range, so you will spend more time hunting for lined-up peaks than charging big cleanup sets.
Winds become more cooperative overall, with ideal offshore conditions at 16%, the highest of the year. Lighter S/SW/SSW flows and spring high-pressure ridges can deliver glassy mornings before the sea breeze kicks in. Water temp is still a fresh 11.2°C, air temp averages 10.1°C, and precipitation eases to 2.84mm/day. May is a great month for a longboard or a groveler, with the occasional bigger WNW swell reminding you what winter felt like.
