Conditions at Luz in May
May: Fading Pulse, Growing Heat
May signals the end of the reliable Atlantic groundswell. Average height falls to 5ft (1.6m) and period to 9.8s - borderline 'average, punchy' but beginning to struggle. The wave rose is now overwhelmingly NW (39.7%) and NNW (23.9%), with the south-to-southeast quadrant contributing only 0.7%. For south-facing Luz, this is almost a flatline; the few waves that wrap are usually windswell and grovelly. Offshore winds are common (57% from N/NNE/NW/NNW, ideal 34%), but it's a case of 'no swell, no party.' Air temperatures become pleasant (17.6°C average, max 30.4°C), water warms to 17.0°C, and rain eases to 1.20 mm/day. Surfers with a longboard will find the occasional fun knee-to-waist high ripple, but don't expect any power.
