San Vicente Rivermouth Surf Forecast and Surf Report

Alright, this is Rusty. Let's get into it.

We're looking at a long stretch ahead, and honestly, for the first week or so, it's a tough watch. The water is sitting at about 71°F, which is a touch warmer than normal for this time of year, a small comfort, but the surf is just not cooperating. The whole scene is pretty flat.

The first real chance of a wave comes late on Monday, the 31st of August. San Vicente Rivermouth is the only spot on the radar, and it's a river mouth setup that's fairly consistent. Monday morning we get a glassy start with a 5ft NW swell and a 10-second period, energy is moderate (425). That's the best looking window in the whole first week. The wind is dead calm, the water is clean, and while the swell isn't huge, it's contestable. The afternoon turns a bit messy with a tricky offshore wind, but that morning session is the one. For a river mouth, though, be aware the crowds are possible here.

After that, the surf just drops off a cliff. From Tuesday, September 1st, right through to the 4th of September, we're looking at tiny, weak junk. Swell heights hover around 2ft to 2ft, with periods all over the place but mostly in the 8-10 second range, and the energy is pathetic (under 100). It's basically a lake.

Then, keep your eye on Saturday, September 5th. The morning shows a serious pulse of energy – a 6ft NW swell, with a very long 14-second period. The combined energy is strong, hitting 1428. The wind is a light cross-shore, which is fine. This is a big, powerful groundswell. At 6ft, it's getting into the intermediate zone, but for a river mouth, that long period could make it a bit straight and fast. It's a standout if you're an experienced surfer and can handle the power. The afternoon gets ruined by a strong 25 km/h (16 mph) cross-onshore wind, so the morning is the only call.

After that, it's back to small and weak. The 6th of September has a small 4ft swell, but it's messy. From the 7th onwards, we're looking at endless days of 1ft to 2ft junk, with energy levels barely reaching 100. There are some glassy mornings in there, like the 8th and the 10th, but the waves are just too small to care about. The second week of the forecast is a total write-off for any decent surf. The long gap from the 5th of September onward is a real dry spell.

So, the one true standout is the morning of Monday, August 31st for the clean, glassy 5ft swell, and the morning of Saturday, September 5th for the big, raw power. If you're going to paddle out, those are your only real windows.
