Conditions at Pease Bay in May
May: Small-Craft Summer Begins
May is when the North Atlantic storm track starts to weaken and Pease Bay shifts into small-surf mode. Average swell height drops to 3ft (0.9m) and period to 5.7s. The direction data is still dominated by NNE at 20.9%, NE at 15.0% and ENE at 8.4%, but the height bins show most of this is below 1.5m, with only about 11% of observations reaching 1m or bigger from the optimal quadrants. This is the classic grovel range: waist-high, rippable but lacking real power.
Winds become lighter overall, with a higher share of E, ESE and SE breezes. Sea breezes can develop on sunny afternoons and create onshore chop. The ideal offshore S/SSW/SW/WSW window is still present about 15% of the time, so dawn patrol is usually the move. Water temperature rises to 10.0°C, air averages 9.6°C, and precipitation drops to 1.69 mm/day. A 3/2 wetsuit and a smaller board are the tools of the month.
