Conditions at Flagler Avenue in May
May: Small Trade-Wind Swell
May settles into the classic late-spring lull. Average swell height dips to 3ft (1.0m) and period shortens to 7.8s. The wave rose is dominated by E (29.9%) and ESE (25.2%); combined, these two directional sectors make up more than half of all observations, but they are mostly small 2-3ft (0.5-1m) windswell. ENE (16.8%) and NE (9.3%) still offer occasional chest-high waves, especially when a residual mid-Atlantic low lingers. Wind quality suffers as the Bahamas/Bermuda high strengthens: ESE (12.8%), E (11.9%) and SE (11.0%) winds are the most common, which means plenty of lumpy, onshore texture. Ideal wind sits at 35 percent. With water at 25.8°C (78°F) and air averaging 24.8°C (77°F), it's warm enough to surf in boardshorts - just bring a groveler. Rainfall begins to increase with 3.09 mm/day.
