The Streets - surf spot statistics

Best Surf Season (October - March)

The North Atlantic winter pattern delivers the most consistent and sizeable east-to-northeast swell to The Streets. During these months, average wave heights hover around the 0.9-1.0m mark with average periods in the 7.5-8.5s range, offering plenty of rideable, punchy surf. The frequency of offshore winds from the SW-WNW quadrant peaks at 10-15% of the time, providing cleaner conditions more often. Stronger low-pressure systems tracking along the coast can generate powerful long-period swell from the NE and ENE, occasionally pushing into the 'pumping' and 'firing' categories (1.5-2.5m). While the onshore wind still dominates, the increased swell energy and better windows of offshore flow make this the prime time for The Streets.

Fair Surf Season (April & September)

April and September serve as transitional months. Swell heights drop to around 0.8m on average, and periods remain reasonable but the frequency of ideal offshore wind decreases to around 12%. September benefits from a slightly longer average period (8.6s) as early-season tropical systems or distant storms send pulses of longer-period energy. However, wind consistency is a challenge – the trade winds begin to strengthen in spring and persist into early autumn. Expect a mix of small to fun-sized waves, with occasional better days when the wind aligns.

Low Surf Season (May - August)

The summer months bring a significant downturn in surf quality at The Streets. Average wave heights drop below 0.7m, often in the 'too small' to 'small' range, with periods lingering in the average zone. The east to southeast trade winds lock in for most of the summer, blowing directly onshore and ruining the wave surface. Ideal offshore wind occurs only 9-11% of the time. The predominant swell from the east and southeast is typically local windswell or small trade wind swell, lacking the power of winter groundswell. This is the low season – best for groveling boards and patience, as the occasional long-period hurricane swell or distant storm can fire up the spot, but it's rare.

March: Transitional Swell with Late-Winter Bite

March sees the average swell height holding at 0.9m with a period of 7.9s – still in the average, punchy category but with a slight uptick in period. Swell direction is still east-dominated (E 22.7%, ENE 17.3%), but the northern component begins to wane (NNE 7.5%, NE 13.7%). The percentage of offshore wind drops to 13% as spring weather patterns become more variable. The wind rose shows a spread of directions, with E (9.0%) and ESE (9.2%) leading the onshore flow. However, W (5.6%) and WNW (5.5%) still offer offshore potential. The combination of lingering winter groundswell and improving period means that when the wind cooperates, The Streets can see clean, fun waves. Late-season cold fronts can still deliver a spike in size from the northeast.
