Conditions at Streedagh Strand in May
May: Small but Fun-Sized
By May, the North Atlantic storm track is winding down. Average surf height is down to 3ft (0.9m) and the average period is only 9.6 seconds, so most of what arrives is a mix of decaying groundswell and windswell rather than powerful, well-organized lines. Swell direction remains favorable on paper - WNW 25.7 percent, NW 19.6, NNW 19.5 and W 16.4 - but the bulk of the energy sits in the grovel zone below 3ft (1m).
Wind consistency also takes a step back. The most dominant wind direction is NNW at 11 percent, often bringing cool, onshore wind straight into the beach. The ideal offshore window from E/ESE/SE/SSE exists around 25 percent of the time, with the overall clean surf percentage at 23 percent. Water temperatures reach 11.4°C and air temperatures average 10.9°C, so May can be pleasant for a longboard or funboard, but big-wave hunters will still be waiting for autumn. Rainfall is moderate at 2.65 mm/day.
