San Vicente Rivermouth Surf Forecast and Surf Report

Hey folks, Rusty here. Let's be straight with you – the forecast for the next couple of weeks over at San Vicente Rivermouth is a real mixed bag, and honestly, it's looking pretty flat and messy for the most part. We've got a solid 16-day window to look at, but the first few days are a write-off, so don't rush down there just yet.

The water temperature is sitting at 73°, which is a touch warmer than normal for this time of year, so at least you won't be freezing your butt off while you're waiting for a set.

We start off with a long, quiet stretch. From Monday the 24th right through the rest of that week, it's just poor surf conditions with tiny, weak swell. Most days the combined energy is under 100, which is pretty weak. A little pulse of energy shows up on Thursday the 27th with a 3 ft NW swell at 10 seconds, but it's still just ordinary. The water's glassy in the morning, but the waves are barely there.

Friday the 28th morning sees a bit of a bump – a 5 ft WNW swell with a period of 11 seconds and a cross-shore wind. The combined energy hits 744 (moderate), but it's still a marginal forecast. The afternoon chops up again. Honestly, nothing here is worth getting excited about.

The first real glimmer of hope comes on Sunday the 30th morning. The swell is a tiny 3 ft from the NW, but the wind is glassy and the conditions are clean. It's surfable, but very ordinary. Still, it's your best bet for a tiny, clean wave in the first week.

We then get another run of marginal conditions through the end of August and into the first week of September. The swell from the NW starts to build, but it's always accompanied by a cross-onshore wind that messes up the surface. On Monday the 31st afternoon, we see a 5 ft NW swell with glassy conditions, and the combined energy is 250 (moderate). That's a small window of clean, but still small, surf.

The biggest energy of the entire forecast shows up on Friday the 4th of September. The afternoon brings a 10 ft NW swell with a 10-second period, and the combined energy is a massive 1631 (very strong!). That's expert-only territory, and the wind is a moderate cross-shore, so it'll be a chunky, bumpy wall for the brave. Definitely not for beginners.

The tail end of the forecast, around Sunday the 6th of September morning, looks promising. We get a 5 ft NNW swell with glassy conditions and a combined energy of 560 (moderate). The wind is glassy, and the forecast says "expect good surf conditions." That's your standout. It's about a week and a half away, so keep an eye on it, but it's the best chance for a clean, fun-sized wave.

The very last day, Monday the 7th, has a long-period 3 ft WNW swell at 15 seconds. That's a groundswell, and it'll be best for the rivermouth setup, but the wind is light and cross-shore, making it marginal. The period is long, so there will be long waits between sets.

To wrap it up: the first week is a total dud. Your best bet for a clean, decent session is the morning of Sunday the 6th of September. If you're an expert and want to wrestle with some serious power, the afternoon of Friday the 4th of September is on the cards, but it's a meaty, bumpy one. Keep checking the forecasts, as things can change.

Rusty.
