Conditions at Tapia de Casariego in March
March: Unstable Shoulder Season Power
March starts to feel the earth tilting toward spring, but the North Atlantic hasn't gotten the memo just yet. Average wave heights ease slightly to 4.9ft (1.5m) and periods still come in at a solid 11.8 seconds. The swell direction table shows a near-perfect window: NW at 35.2%, NNW at 25.0% and WNW at 12.1%, with only 4.7% from straight N - meaning the vast majority of the energy is aimed directly at Tapia's north-northwest-facing sand. The heavier sets are still present; over 6% of the NW sector is in the 6.6-8.2ft (2-2.5m) range. However, the ideal wind percentage drops to 43% as the Azores High begins to flex, bringing more ENE (17.0%) and NE (8.1%) breezes that create onshore texture. The good days - when SSW (11.5%) and SW (13.2%) offshore flow align with a fading low pressure - are as good as anything in winter. Air temps warm to 10.2°C, water stays at 13.0°C, and you can still score all-time sessions if you're ready to gamble on the forecast.
