The Lowdown
Alright, let’s be real with you. I’ve stared at the charts for the next couple of weeks, and I’ve got to be straight: it’s looking pretty flat out there. We’ve got a real dry spell on our hands. It’s not a total blank, but you’re gonna have to pick your moments, and even then, you’re mostly chasing knee-to-waist-high dribble if you’re lucky.
The next few days are a write-off, to be honest. Tuesday and Wednesday mornings are just about dead, with the odd ripple sneaking in. You’ll see some tiny stuff around the 0.7ft mark with a short period, but there’s no push, no power. The combined energy is weak, with values barely scratching double digits (9). It’s more of a float-around-with-your-coffee situation than an actual surf. There are some glassy windows early on Wednesday and you might get one or two crumbly little waves on the inside, but don’t get your hopes up. The wind is mostly light, but that doesn’t matter when there’s no swell to groom.
We have a few more days of this in the first week. Thursday's got a bit of same-same – a little 1ft bump, still short period, and the energy’s still in the weak range (8). The mornings look clean with light winds, but again, it's just not doing anything. The swell direction is from the NNE, which is not what Dogmans (Rincon) really wants. It’s a reef setup that needs some solid WNW groundswell to wake up. This is just wind-slop and leftover energy.
Towards the end of the first week and into the weekend, things get even smaller. Friday and Saturday barely register anything on the buoy. There’s a couple of glassy mornings, with the swell dropping to that 0.7ft mark, but it’s just not surfable. We’re looking at several days with no real recommendations at all. It’s a quiet, empty stretch.
Now, there is a tiny blip of hope. Towards the end of the first week of September, around the 1st, we see a couple of instances where the period stretches out a bit. This long-period energy, around 11 seconds, is a hint of something, but the height is still tiny at 0.7ft. The energy is still weak, maxing out at (12), but the direction shifts slightly more to the NNE. On the morning of the 1st, it’s dead glassy with a bit of a pulse. It’s not going to be a classic, but if you’re desperate, that’s your best window for a few small, cleanish waves. This is a long way out, so I wouldn’t book a trip around it, but it’s something.
Beyond that, the guidance just shows more flatness, with a few speculative 0.3ft pulses that are just not worth paddling out for. The water temp is about average for this time of year, nothing crazy there.
So, the honest take is this: we’ve got a good long stretch of nothing. If you’ve got a log and a lot of patience, you might find a bump, but the standouts are far and few between. The best bet is that morning on September 1st. It’s promising because of the long period and the clean conditions, but it’s still tiny. This looks like it could be a better week for messing around on a SUP or just enjoying the beach. Keep the board waxed, but don't be surprised if you're watching the horizon more than riding it.
Stay patient.

Information about the Dogmans (Rincon) Surf forecast
The above surf forecast table for Dogmans (Rincon) provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dogmans (Rincon) can be found by selecting the local surf guide option on the grey menu. Our Dogmans (Rincon) surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Dogmans (Rincon)) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
