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 September

September: The Reawakening

September brings a significant turnaround as the Atlantic hurricane season peaks and the first cold fronts of autumn begin to stir. Average swell height reaches 1.2m with period jumping to 8.8s – a noticeable boost in power. Most importantly, the swell direction shifts: NE (19.6%) and NNE (6.9%) re-emerge, now combining for 26.5% of the total energy, while ENE still leads at 48.7%. Ideal wind conditions from the S-SSW dramatically improve to 46% of the time, thanks to lighter trade winds and occasional southerly flow. This creates more frequent windows of clean, lined-up surf with punchy, rideable waves. September is a surprise gem for those willing to watch the tropical models.
