North Street seasonal overview
Best Surf Season (September - November)
The Atlantic storm track becomes more active through September and October, and North Street finally lines up. Tropical systems spinning up off the East Coast deliver E, ESE, SE and SSE swells directly into the SE-facing beach, while early-season cold fronts supply W and NW offshore winds for grooming. September's 8.4s average period is the year's highest, so even though average heights sit around 4ft (1.2m), the sets have proper push. November keeps the momentum going as nor'easters and large extratropical lows take over from hurricanes. The best windows come when a strong low passes east of the beach and the wind flips to the west-northwest quadrant.
Fair Surf Season (December - April)
Winter delivers more raw power but North Street's optimal swell window gets smaller. S, SSW and ENE swells become more dominant, meaning a lot of the energy hits the coast at an awkward angle or gets blocked altogether. Frequent W, WNW, NW and NNW winds keep things clean, and the 4-5ft (1.3-1.5m) average heights keep the spot alive, especially during positive NAO phases with a faster-moving storm track. By April, the spring transition begins to mix in more southerly and SSW winds, so sessions become a gamble between fun E-SE groundswell and lumpy surface conditions.
Low Surf Season (May - August)
Summer is the most consistent but least powerful time of year. The Bermuda High establishes itself and pumps constant E to SSE windswell toward North Street - often 60 to 70 percent of all swell energy in the June-August peak. However, average wave heights shrink to around 3ft (0.9m) and periods settle at 7 seconds, so good days are groveling rather than grinding. The onshore component of S and SSW winds also increases, leaving the surface bumpy. With water temperatures reaching low-to-mid 20s Celsius, it is a great time to get wet on a longboard, but for proper surf you will be waiting out the next hurricane blip or synoptic wind event.
