Conditions at Espinho in May
May: Late Spring Lulls and Fun-Sized Windows
May marks the beginning of the summer lull at Espinho. Average swell height drops to 3.6ft (1.1m) and period to 9.9s, placing most waves in the average, punchy category rather than the powerful long-period class. Directionally, the swell becomes more northwesterly: NW accounts for 34.8% and WNW 38.5%, with W at 18.6%. This is classic spring-time North Atlantic windswell mixed with older groundswell, plenty of 3-5ft (1-1.5m) waves, but less consistency overhead-plus.
The bigger issue is wind. Ideal conditions fall to just 22%, as the northerly pressure gradient cranks up; NNW wind appears 30.5% of the time and NW another 10.9%. These winds blow from an onshore/cross-shore direction for the west-facing beach and tend to make the lineup bumpy. The best windows come early in the morning before the sea breeze strengthens, or when a passing low from the Azores pushes in ESE and E winds. Air temperature averages 15.9°C, water temperature climbs to 15.8°C, and precipitation is low at 2.40 mm/day. It is still possible to find fun, groveling waves and the occasional rippable day, but expectations should be tempered.
