Conditions at Gaztetape in May
May: Clean but Smaller
May sees the North Atlantic wave machine winding down further. Average swell height falls to 1.2m (around 3-4ft) and period to 9.9s - in the 'average, punchy, rideable' category. The swell direction is overwhelmingly favorable, with NW at 51% and WNW at 28%, but the energy is much smaller: the majority of waves fall in the 0.5-1.5m (1.5-5ft) range. This is classic groveling-to-fun surf. Ideal wind is down to 29%, and the onshore northerly flow becomes more common. Still, when the sea breeze stays away and a southern wind sets in, the beach can deliver clean, rippable waves, especially with the longer-period NW groundswell.
Air temp 15.2°C, water 16.1°C, rainfall 2.21 mm/day - conditions start to feel more spring-like.
