Pavones seasonal overview
Best Surf Season (March - April)
March and April deliver the sweet spot of the year at Pavones. During these months, the trade wind inversion weakens and the Intertropical Convergence Zone shifts, allowing more frequent pulses of offshore winds from the SW and SSW quadrants. The average wave period peaks near 14 seconds, bringing powerful, organized lines from the South Pacific. Swell heights in the 1-1.5m range become more common, producing rippable, fun-sized waves. While the dominant swell direction remains SSW, the improved wind statistics (37% ideal in March, 36% in April) mean more clean, glassy sessions on the long left point.
Fair Surf Season (May - July & November - February)
May through July sees the largest average swell heights of the year (1.1m) with a consistent mix of 0.5-1m and 1-1.5m groundswells. The wave period remains solid at 13-14 seconds, but the wind becomes a more frequent adversary. A stronger onshore component from the WNW and NW increases the chop, dropping ideal wind percentages to the 25-31% range. November through February offers a slight reprieve: the early dry season brings lighter winds overall, and while swell heights dip to 0.7-0.8m, the long period (12-13s) still produces punchy, rideable waves on the better days. Windows of clean offshore flow are shorter but can still deliver great sessions for those who time it right.
Low Surf Season (August - October)
The heart of the rainy season from August through October is the most challenging period for consistent quality surf at Pavones. The Intertropical Convergence Zone sits overhead, driving persistent onshore winds from the west and northwest. Ideal wind percentages bottom out at just 20-25% of the time. Swell energy remains present (average 1.1m) but often arrives with a high-frequency chop that makes the waves messy and difficult to ride. The wave period also drops slightly (12.9-13.2s), further diminishing the shape. While an occasional tropical wave or southern hemi storm can fire up the point, the overall odds of clean conditions are at their lowest. Patience and a sharp eye on the forecast are essential.

Conditions at Pavones in September
September: Rainy Season Grip
September is the most challenging month for consistent quality. Swell height remains at 1.1m, but the composition shifts: 56.2% in the 1-1.5m range, plus a notable increase in SW swell (7.1%), which is slightly more favorable. The period dips to 13.2 seconds. Wind quality hits the yearly low at 20% ideal. The WNW direction dominates at 23.7%, and W winds add another 16.1% — most of these are onshore and often moderate (10-20 kph). The Intertropical Convergence Zone keeps conditions humid and often overcast. While the swell is consistent, clean waves are rare gems. Patience and flexibility are key.
