Conditions at Sao Pedro de Moel in April
April: Spring Slump Begins
April is a classic spring shoulder month. The average swell height falls to 1.8m (6ft) and periods shorten to 11.2s - enough for a fun session, but lacking the raw power of winter. The swell direction is still favourable, with NW (30.7%) and WNW (26.6%) leading, plus NNW (14.4%) and W (8.4%). Most waves are in the 1-2m (3.3-6.6ft) range, and there are fewer big sets.
Wind is where April struggles. Ideal wind is only 20% of the time. The pressure gradient tightens as the Azores High builds, driving persistent NNW flow (28.2%) with moderate-to-strong speeds (10-30kph is common). Offshore E/ESE/SE/SSE winds make up just 12.5% of the total. On the bright side, water temp rises to 15.3°C (60°F) and air temps average 13.8°C (57°F), so it's more comfortable. But the onshore northerly winds often chop up the swell. April still offers rideable waves, especially on dawn patrol windows.
