The Streets seasonal overview
The Streets in the United States offers varying surf conditions throughout the year, with the best months typically being September through December. During this period, ground swell percentages increase significantly, peaking in September at 22%, while wind swell remains consistent or slightly elevated. Swell sizes also improve, averaging around 0.7–0.9m, providing more surfable waves. Wind conditions remain challenging year-round, with good wind days rare (10–18%), but late fall and early winter (November–December) see a slight improvement. The worst conditions occur in summer (June–August), where no-swell days dominate (52–61%), and swell size drops to 0.5m. Early spring (March) also shows decent ground swell (16%) but suffers from consistently poor wind conditions (85% bad). For the most reliable surf, target September–December when ground swells are stronger and swell size is more favorable, though always be prepared for tough wind conditions regardless of season.

Conditions at The Streets in September
September at The Streets offers generally small but rideable conditions, with an average swell height of 0.7m and a decent period of 9.4s—indicating some energy, though waves tend to stay in the knee-to-waist-high range. The swell is predominantly from the east (E and ENE directions), making up over 50% of the waves, with most falling between 0.5-1m. However, only 12% of wind conditions are ideal for surfing, as easterly and northeasterly winds (10-20kph range) dominate, which can create choppy or cross-shore conditions. Cleaner sessions are rarer but possible when lighter winds align. Expect smaller, softer waves with occasional waist-high+ sets; best suited for longboarders or those chasing mellow rides rather than heavy barrels. Windswell from the E/ENE can provide consistency, but quality depends heavily on wind cooperation.
