Conditions at Zavial in May

May: Summer Stability Arrives

May sees a real drop in Atlantic muscle. Average swell is down to 4-6ft (1.2-1.8m), and average period slips to 9.8 seconds. The swell rose is now almost entirely NW (39.7%), NNW (23.9%) and WNW (16.7%), with S/SSW/SW energy at barely 1%. The wind follows suit: NNW (32.1%) and NW (19.9%) dominate, and ideal wind windows are just 31%. Once the land heats up, those afternoons become seriously textured by sea breeze, so early is better. Water temperature reaches a comfortable 17.0°C, air highs can touch 30.4°C and precipitation drops to 1.20mm/day. It is fun, small, increasingly summer-like - a groveler's month rather than a heavy-wave month.
