May: Small Summer Swells Arrive
May marks the transition into the low season. Average wave height drops to 4ft (1.2m), while the period backs off to 10 seconds. NW swell becomes the dominant source at 40 percent, followed by WNW at 33 percent, but nearly all of that energy is in the 3-4ft (0.9-1.2m) range. There are still clean, fun-sized days, but the ideal-wind percentage falls to 27 percent as the Azores High begins to build. The wind data shows a strong NNW flow at 26 percent and a healthy NW component, which keeps the sea surface choppy in the afternoons. Air temperatures are mild at 18.2°C, water temps rise to 16.3°C, and rainfall is decreasing. If you pick the right tide and find an offshore easterly morning, May can offer quiet 3-4ft (0.9-1.2m) peaks.
