Bozo seasonal overview
Best Surf Season (October - March)
The winter months bring the North Atlantic storm track to life, generating consistent long-period swells from the N to NE quadrant – exactly what Bozo's NNE exposure is built for. Average heights hover between 1.5 and 1.6m with periods averaging 9.3-9.4s, delivering punchy, rippable waves day after day. While the dominant trade winds often blow from the E-ESE, keeping conditions choppy, the windows of offshore flow from the S-SSW (occurring 21-43% of the time) turn the lineup into a surfer's paradise – glassy, groomed faces that make the most of every incoming pulse.
Fair Surf Season (April & September)
Shoulder months see a transition. April retains a decent mix of NE and NNE swell (over 40% combined), though average heights drop to 1.3m and periods slip to 8.9s. September marks the return of longer-period swell (8.8s) with a growing NE component (26.5% from NE/NNE) as hurricane season stirs the Atlantic. Both months offer improved wind statistics (25% and 46% ideal wind, respectively), but the swell quality is more hit-or-miss compared to the peak season.
Low Surf Season (May - August)
During the summer months, the tropical trade wind regime locks in. Swell is dominated by E and ENE directions (over 75% combined), which are not optimal for this NNE-facing spot, resulting in small, weak, short-period waves averaging 1.1-1.2m and 7.2-8.1s. Constant onshore winds from the E and ESE further degrade wave quality. While the percentage of ideal wind (offshore) actually increases to 31-37% due to lighter overall conditions, the swell direction and size rarely cooperate. Small, groveling waves are the norm, with occasional exceptions from hurricane swell or distant storms.

Conditions at Bozo in October
October: The Surge Begins
October fully commits to the transition toward winter. Average swell height holds at 1.2m but period strengthens to 9.1s, and the directional mix becomes heavily weighted toward the optimal NE band at 35.9%, with NNE at 13.0% and ENE at 38.9%. The total optimal swell (N through NE) surpasses 50% for the first time since March. Ideal wind from the S-SSW is generous, occurring 43% of the time as the trades weaken and cold fronts bring more variable pressure patterns. The result is an increasing number of days with peaky, solid chest-to-head-high waves groomed by light offshore breezes. October is the month surfers wait for all summer – the rhythm is back.
