Barra de Potosi • Surf Spot Statistics

Best Surf Season (June - October)

From late spring through early autumn, the southern hemisphere storm track becomes the main engine for Barra de Potosi. A steady diet of long-period SSW and SW groundswell, averaging 4-5ft (1.2-1.5m) at 13-14 seconds, arrives across the Pacific and puts this WNW-facing stretch into play. This is also the window with the most reliable clean wind, with ideal surf conditions running 40-48% of the time from June through October. Expect the best sessions in the early morning before the afternoon sea breeze and the North American Monsoon take over. While this is the wettest time of year, the combination of powerful, consistent swell and better wind windows makes it the standout season.

Fair Surf Season (March - May & November)

The transition months produce some of the longest-period swell of the year, especially April and May, when periods average 14.1-14.2 seconds and the 1.5-2m (5-6.5ft) range becomes more common. However, the wind blows less favourably, with ideal clean windows only around 9-13% of the time from March through May. Between pulses, expect more lumpy, wind-affected surf, with quality depending on dawn glass and the exact angle of the W/SW energy. November offers a similar story: solid SSW/SW groundswell at 4ft (1.2m) and a 13.3-second period, but with a return of stronger NW/NNW breezes.

Low Surf Season (December - February)

Winter is the smallest and most inconsistent period at Barra de Potosi. Average swell heights drop to 3.3-3.6ft (1.0-1.1m), and although periods stay long around 13.2-13.4 seconds, the energy is largely confined to the SSW/SW/WSW window rather than the more favourable W/NW angles. Frequent light-to-moderate NNW and NW winds, plus only 18-23% ideal wind days, make the surf harder to time. Still, when a late-season North Pacific front sneaks a W swell into the mix and the wind follows a light offshore land breeze, the place can turn on. Just be picky with your sessions.
