Conditions at Furadouro in May
May: Longboard Season Takes Over
May slides into summer mode. Average swell height is 3-4ft (0.9-1.2m) and period drops to 9.9s, meaning less power and more short-period swell. The direction mix is split between WNW 38.5% and NW 34.8%, with W adding 18.6%; the source is fine, but the energy is increasingly wind-driven and small. Ideal wind plummets to 20% as the Azores High flexes and the northerly regime locks in. NNW dominates the wind rose at 32.6%, adding constant cross/onshore chop to the surface. Water temperature reaches 16.0°C, air temps average 15.9°C with highs near 30°C, and precipitation averages 2.40 mm/day. Keep expectations in check and the longboard close; clean, punchy head-high days will be rare but memorable.
