Conditions at Sao Pedro de Moel in May

May: Small and Windy

May is a preview of summer. The average swell drops to 1.5m (5ft) and periods shorten further to 10.0s. While the direction remains correct - NW (35.2%), WNW (23.7%), NNW (21.7%) and W (10.4%) - the heights are increasingly small, with a strong portion in the 0.5-1.5m (1.6-5ft) range. The punchy winter groundswells are gone, replaced by weaker, shorter-period swell.

Wind becomes the biggest obstacle. Ideal wind is just 15%. NNW dominates with a massive 37.5% of all wind observations, and 16.4% of those are in the 20-30kph range. This creates constant onshore/ cross-shore bump. Offshore E/ESE/SE/SSE winds total only 7.3%, mostly light. Water temp warms to 16.4°C (62°F) and air averages 16.4°C (62°F), with precipitation down to 2.05 mm/day. May is for the diehards - bring a grovel board and pick the rare glassy morning.
