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 December
December at The Streets offers relatively small but surfable conditions, with an average swell height of 0.8m and a decent period of 8.9s, suggesting some organized energy. The most consistent swell direction comes from the E/ENE, contributing the majority of waves in the 0.5-1.5m range (peaking at 23.21% for 0.5-1m from the E). Larger waves (1.5-2.5m) are less frequent but occur mostly with ENE/NE swells. Wind conditions are a mixed bag—only 18% of the time is ideal for surfing (likely light offshore or light cross-shore). The predominant winds come from the N-NNW quadrant, often blowing 10-30kph, which can create choppy or onshore conditions. Surfers should target days when ENE/E swells align with lighter winds, as stronger NW/N winds will degrade quality. Overall, it’s a fair month for intermediate surfers, with the best windows being early morning or during wind lulls.
