Conditions at Stone Harbor in May
May: Summer Flatness Looms
May is when the Bermuda High begins to take control. Average swell height drops to 0.5m (1.5ft) with a period of 6.7s, and ideal surfing wind plummets to just 3%. The swell direction distribution becomes dominated by ESE, SE, SSE and S, combining for over 60% of observations, but the 1-1.5m class is almost non-existent. Onshore SW and SSW winds are common, and afternoon sea breezes add extra chop to an already starved wave field. Water temperature warms to 15.3°C and air averages 15.7°C, which makes for pleasant beach weather but poor surf. If you're chasing waves, your best bet is a dawn patrol on an overcast morning before the southerly flow kicks in, or a rogue late-season low that briefly breaks the groveling pattern.
