Conditions at Achadas da Cruz in May
May: Summer Swell and Trade Winds
The days are longer and the Atlantic energy begins to fade. Average swell height falls to 1.7m (5.5ft) and period drops to 10.0s, meaning the waves lose their winter push. The direction remains favourable in orientation - NNW (34.2%), NW (16.9%) and WNW (8.8%) - but the heights are concentrated in the 1-2m (3-6.5ft) range. The wind story is more critical: NNE (27.6%) and NE (17.2%) dominate the coast, and ideal offshore wind is present only 11% of the time. This makes May a marginal month - fun, rippable waves when the wind aligns, but not the consistent quality of winter. Water temps warm to 19.1°C and rainfall tapers off; a 3/2mm wetsuit starts to feel good.
