Conditions at 7 - 11 in October
October: The Atlantic Roars Back to Life
The North Atlantic storm track begins to organize in October, and 7-11 responds immediately. Average wave heights climb to 1.1m (3.5ft), average periods hit 7.8s, and the harvest of E/ESE/SE/SSE swells is plentiful, with plenty of 0.5-1.5m (2-5ft) energy filling the directional bins. This is one of the best months for quality on the eastern seaboard: there is enough leftover tropical energy to create long-period groundswell, while the first strong cold fronts of autumn start dragging in clean NW winds.
Ideal wind conditions run at 45%, with the W/WNW/NW/NNW cluster well represented. Water temps have dropped to 18.2°C and air temps average 15.1°C, so it's autumn wetsuit weather. Watch the synoptic map for a low pressure system exiting New England: that usually means an ESE swell and offshore wind the next morning.
