Conditions at Serapo in May
May: The Flat Spell Begins
By May, Serapo's surf appetite hits a seasonal drought. Average wave height drops to around 1.5ft (0.5m), period to 4.6s, and ideal wind plummets to 14 percent. The swell window is still dominated by W at 34 percent and WSW at 18 percent, but nearly all of that energy is in the sub-1.5ft (sub-0.5m) range, classic Mediterranean summer windswell. The wind pattern becomes more thermal: WSW and W winds are common in the 10-20kph range, and the afternoon onshore push routinely kills whatever small waves exist. If you are keen, look for early mornings with a light N-NNW breeze and a pulse of SSW/SW windswell; these rarely exceed 3ft (1m), but Serapo can still offer small, fun-sized, grovelly waves. Water temperatures are warming quickly at 18.9°C (66°F), air temps averaging 18.7°C (65.7°F).
