Banzai - surf spot statistics

Banzai, Italy, is a surf spot that experiences variable conditions throughout the year, with distinct seasonal trends in swell and wind. The best months for surfing are typically during autumn and winter, when ground swells are more frequent and wave heights are more substantial. January and December stand out as the most favorable months, offering the highest mean swell size (1.3m) and relatively higher percentages of ground swell (23% and 21%, respectively). While wind conditions are predominantly onshore or unfavorable (90% bad wind conditions in January and December), these months still provide the most consistent wave energy. Late autumn (November) is another solid window, with decent ground swell (18%) and manageable wind ratios. February and March also deliver reasonable surf, though with slightly smaller waves (1.2m–1.1m) and similarly challenging winds. Spring and summer bring weaker conditions, with April through September seeing a significant drop in ground swells (often below 15%) and smaller average wave sizes (0.7m–0.9m). Wind conditions remain poor, peaking in August with 92% unfavorable winds and minimal swell activity. While summer months may occasionally produce wind swells (around 40%), they are generally unreliable for quality surfing. October marks the beginning of the transition back to better swells, but wind issues persist. Overall, the prime surf season at Banzai runs from November through March, with winter offering the most powerful and consistent waves despite the challenging winds. Surfers should prioritize these months for the best chances of good rides.

In November, Banzai sees an average swell height of 1.2m with a moderate period of 6.6s, indicating mostly small to mid-sized waves. The swell distribution shows a higher likelihood of rideable conditions when coming from the S, SSW, and SW directions, where wave heights frequently reach 1-2.5m—ideal for intermediate surfers. Westerly (W, WSW, WNW) swells also contribute to larger waves (1.5-2.5m+), but these are less consistent. Wind conditions are crucial, with only 12% being favorable for surfing (typically light offshore or cross-offshore). Unfortunately, winds are often onshore from the S/SSW or strong northerlies, which can degrade wave quality. For surfers, the best windows will be during smaller SSW/SW swells paired with light E/NE winds, though consistency is limited. Expect mostly smaller, weaker waves with occasional clean(er) days—patience and timing are key.
