The Lowdown
Alright, Rusty here. Let’s break down what we’ve got.
To be honest, it’s a grim outlook for Dogmans (Rincon). This reef break is usually fairly consistent and likes a WNW swell, but the next couple weeks are looking flat as a pancake. Water temp is about 83°F, which is normal for this time of year, so that’s no surprise.
The first tiny pulse shows up Monday, August 17th – a 0.7ft wave from the NNE with a 10-second period. Combined swell energy is weak at 10, and with a NE cross-off breeze around 12 mph, it’s clean but tiny. Poor surf conditions all around.
Then we hit a long dry spell. From Tuesday, August 18th through Saturday, August 22nd, we’re looking at 0.3ft to 1ft waves at best. Winds are sometimes glassy, sometimes offshore, but there’s just no power. The combined energy rarely hits double digits.
Sunday, August 23rd and Monday, August 24th offer zero swell – absolutely nothing. Tuesday, August 25th brings a 0.3ft wave with a 12-second period, but it’s blown out by a 16 mph NNE wind. Not worth it.
The rest of the month stays small. Thursday, August 27th shows 0.7ft from the NNE with a 10-second period and clean winds, but the combined energy is only 9. Same story on the 29th and 30th: 0.7ft, 12-second swells, clean winds – still tiny.
The closest thing to a “best” option might be the mornings of Monday, August 31st and Tuesday, September 1st. Glassy conditions, 0.7ft of 11-12 second NNE swell, and combined energy around 12-14. It’s clean, but you’ll be fighting for a knee-high wave.
No true standouts here. It’s a classic flat spell for the area. Forecasts can always change, but for now, keep the board in the car and the expectations low.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Dogmans (Rincon) may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
