Conditions at Isla de Santa Marina in May
May: The Calm Before Summer's Lull
May marks a noticeable drop in energy. The average swell height is 1.2m (4ft) with an average period of 10.0 seconds, which moves the surf into fun rather than firing territory. That said, the direction remains excellent - NW is a huge 53 percent, NNW 22 percent, and WNW 15 percent - so the beach remains very well exposed to what energy is out there. Most days produce clean lines in the 2-4ft (0.6-1.2m) range, ideal for groveling or longboarding.
Ideal wind slips to 40 percent, making this the trickiest month of the spring for finding clean conditions. The wind rose shows a growing E/ENE component, but also strong WNW and W flow at 10-20kph, which can add texture on the surface. Sea temperature rises to 15.6°C and air temps are pleasant at 14.8°C, with less rain. It is a beautiful time to be at the beach - just don't expect winter-level power.
