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.

May: The Onset of a Slow Summer Pattern
May marks a definitive shift toward smaller, weaker surf as the trade wind regime takes over. Average swell height drops to 1.2m and period slides to 8.1s. Optimal swell from NE and NNE accounts for just 25.7% combined, while ENE and E swell combine for a massive 72.4%. These directions are less favorable for Bozo's NNE exposure, leading to less consistent wave shape. On the positive side, ideal wind from the S-SSW increases to 34% of the time, often in the early morning with lighter conditions. But the waves themselves require groveling boards for anything resembling a good ride – it's a month for small-wave fun, not heavy sessions.
