Conditions at Orio in May
May: Smaller Swell and Sea Breeze Season
May is where the summer pattern begins to eat away at Orio's winter quality. Average swell height drops to 4ft (1.2m), wave period shortens to 9.9s, and ideal offshore wind is down to 28 percent. Swell direction is still overwhelmingly good: NW supplies 51 percent, WNW 28 percent, and NNW 13 percent. But the size distribution is much softer, with most waves in the 0.5-1.5m bracket - fun on the right bank but far from powerful. The wind rose reveals the real issue: NNW, NW and WNW winds account for about 39 percent of the total wind distribution, driving a daily onshore sea breeze. Mornings can still produce lined-up, glassy shoulders if a light east or southeast wind is present. Air temperatures now hit 15.1°C, water is a spring-like 16.1°C, and precipitation lowers to 2.5 mm/day, making the transition much more comfortable even as the waves back off.
