Mendihuaca Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what's on the cards for Mendihuaca over the next couple of weeks.

Overall, we've got a bit of a slow start. The first real window of interest doesn't kick in until the weekend of the 12th, so don't rush down there just yet.

Through the early part of the week, the wave energy is there in the water (moderate energy around 253 to 464), but the wind is a mess. On Thursday the 10th, we've got a cross-onshore ENE breeze at 9 mph making things choppy, and the following days are similar with light cross-onshore winds. The surf is in the 5 ft to 5 ft range but it's just not clean. The best early offer is Saturday afternoon the 12th. Swell bumps up to 6 ft on a 9-second period out of the NE, and here's the key: the wind goes glassy. The combined energy is strong (529), so the power is there. It's a good shot at some fun, decently sized waves if you can dodge the risk of thunderstorms. This is the standout early window.

From Sunday the 13th through to Thursday the 17th, we slip back into average conditions. The wind turns cross-onshore again, mostly from the E or ENE, with speeds up to 12 mph on Sunday morning. Wave heights hover between 4 ft and 6 ft, but the period stays short (7-8 seconds) and the energy fluctuates between moderate and strong (160 to 426). It's surfable, but nothing to write home about. A small window on Thursday afternoon the 17th sees a clean SSE cross-offshore wind at just 3 mph, but the swell is down to 4 ft, so it's small and clean rather than pumping.

The following week, from the 18th to the 24th, things get really small. We're looking at waves dropping to 2 ft to 4 ft with short periods. There are some glassy periods, particularly on Saturday the 19th afternoon and Sunday the 20th afternoon, but the wave height is tiny, and the energy is weak (as low as 31). Honestly, this is a flat spell. It's not even worth paddling out for most.

But hold on. The real story is brewing for the very end of the run. On Friday the 25th of September, a new groundswell arrives. The swell direction swings to the NW with a long period of 12 seconds, building to 4 ft. The energy jumps to 450 (strong). By the afternoon, it's cleaning up: period stretches to 13 seconds, height hits 4 ft, and we have glassy conditions with energy at 502 (strong). This is a proper surf. That combo of a long period groundswell and glassy wind is rare as hens' teeth around here. For Mendihuaca (a sandbar that's consistent and exposed to NE swell), this is the best offering of the whole outlook. It's over a week away, so treat it as promising but not locked in yet.

The water temp is sitting at 84°, which is bang on average for this time of year (anomaly of only 0.5°). That's normal, nothing to worry about.

Stay tuned. This one might just fire.
