Punta Banco seasonal overview
Best Surf Season (March - May)
March through May is the sweet spot at Punta Banco. The average swell climbs from 2-3ft (0.8m) in March to 3-4ft (1.1m) in May, while the average wave period runs a powerful 13.6-14.1s. More importantly, ideal offshore wind scores are at their yearly peak, led by April's 21% and March's 18%. The SSW/SW swell corridor is virtually the only direction that matters, so the combination of long-period energy and a workable morning offshore breeze makes this the most consistent window for high-quality, rippable waves.
Fair Surf Season (December - February & June - August)
December through February is the cleaner, smaller side of the year: 2-3ft (0.5-1m) SSW groundswell under drier skies, but with less size and ideal wind only 10-14% of the time. June through August is the opposite - the Southern Hemisphere winter kicks up 3-5ft (1-1.5m) SSW swell regularly, yet the ITCZ-driven westerlies and heavy rainfall knock the surface quality down. Both blocks offer fun waves if you work the morning windows before the sea breeze takes over.
Low Surf Season (September - November)
September through November is the toughest stretch. The swell is still present - mostly 3-5ft (1-1.5m) SSW/SW energy - but ideal wind bottoms out at 7% in each month, daily rainfall runs above 8.4mm, and the dominant W/WNW flow keeps the beach onshore and bumpy for long streaks. Occasional dry interludes or tropical disturbances can align the swell and wind perfectly, but they are the exception rather than the rule during the core green season.
