Conditions at Andran in May
May: Spring Slump
May marks the point where Andran's surf quality noticeably fades. Average swell height drops to 1.1m (3-4ft) and the period shortens to 9.8s, meaning fewer long-period groundswells and a growing reliance on windswell and smaller NW pulses. The direction is still predominantly out of the NW (46%) and NNW (30%), but the wave-height distribution shifts heavily into the 0.5-1m (2-3ft) bracket. Fun, rippable waves are possible, but you won't want to be overly picky about size.
Ideal wind percentages fall to just 22%, as the Azores High begins to expand and thermal pressure gradients kick in. ENE/E/NE winds are common cross-shore influences, while onshore NW/NNW winds are frequent enough to spoil the surface at times. The best windows come with a morning S/SW land breeze before the sea breeze takes over. Air temp rises to 14.5°C, water warms to 15.5°C, and precipitation is lower at 2.01mm/day.
