Conditions at Yport in May
May: Summer Doldrums and Groveling Conditions
May is the first genuinely small month of the year. Average wave height falls to 0.8m (2.5-3ft) and the mean period drops to 6.8s, putting the surf squarely in short-period, rideable windswell territory. The wave rose is W-dominated (W 36.8%, WSW 12.1%) with only a small portion of the north/northwest window; NNE 13.6% and NE 9.8% indicate that North Sea swells are still around, but they are rarely clean at Yport.
The wind pattern is also shifting into summer: NE (14.8%) and NNE (9.6%) are the most common, both onshore or cross-onshore for the beach, and the ideal offshore wind percentage is only 12%. Air temperature averages 12.6°C and water temperature is 12.9°C (55.2°F). Surf quality is best at dawn, before the sea breeze and increased boat traffic churn things up. This is longboard and funboard season - expect waist-high, roly-poly peaks rather than real groundswell.
