The Lowdown
Alright, this is Rusty checkin’ in from the beach. Let’s have a look at what Doran Beach has got cookin’ for us over the next couple of weeks.
Alright, truth be told, the start of this run is a bit of a slow burn. We’ve got a solid waitin’ game on our hands. For the next several days, things are lookin’ pretty marginal. The swell energy is there in the water—moderate to strong, with readings like 476 (moderate energy) and 613 (moderate to strong energy)—but the wind and swell combo just isn’t comin’ together for clean, rideable surf. Monday the 17th and Tuesday the 18th are both cross-shore and messy, with small, weak waves. Not worth paddlin’ out for.
We finally get a little window of hope on Thursday morning, August 20. The wind turns clean cross-offshore, and we’ve got a 3ft swell from the WNW with a 12-second period. That’s a nice, long-period groundswell that’ll wrap in with some shape. The energy is moderate (530), and those longer gaps between sets’ll make it easier to get outside. This is your best bet for a clean, fun session in the first week.
Heads up for Friday the 21st—it’s a write-off. Poor conditions, strong wind, and a messy swell. Don’t bother.
Saturday the 22nd through Sunday the 23rd is more of the same small, cross-shore mush. Nothin’ to write home about.
Now, lookin’ ahead to the second week, things get a little more interesting but also a bit more unpredictable. Thursday morning, August 27, could be a good one. We’ve got 5ft from the NW with clean offshore wind and moderate energy (376). That’s a solid, clean wave for a rippable session.
Friday morning, August 28, is another standout contender: a 2ft SW groundswell with a 16-second period and clean cross-offshore breeze. The energy is strong (525), and those super-long-period waves will wrap in nice and clean, but they might break a bit straight on the beach. Still, for a point or river mouth, that’d be gold.
The end of the month is lookin’ dicey for beginners. On Sunday the 30th, we see an 8ft swell from the NW with a short 7-second period—big, chunky, and only for the experienced crew. And on Monday the 31st, it ramps up to a 10ft WNW swell. That’s expert-only territory, and honestly, it might just be too much for Doran Beach altogether, with a note sayin’ it could be too big for the break.
The standout? Thursday morning, August 27 and Friday morning, August 28 are your best windows. The 27th gives you clean 5ft NW swell with gentle offshore wind. The 28th offers a smaller but longer-period SW groundswell with glassy conditions. Two good sessions to pencil in.
Water temp’s sittin’ around 59°F, which is about 1°F warmer than normal for this time of year—nothin' crazy, just a touch mild. Doran Beach itself is beginner-friendly but inconsistent, and it can get crowded sometimes, so expect company if the surf’s any good.
Overall, it’s a slow start, but patience pays off mid-to-late week. Keep an eye on the horizon.
Rusty.

Information about the Doran Beach Surf forecast
The above surf forecast table for Doran Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Doran Beach can be found by selecting the local surf guide option on the grey menu. Our Doran Beach 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 (Doran Beach) 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 Doran Beach 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.
Doran Beach is 29 km (18 miles) from the city of Rohnert Park. If you plan a vacation in Sonoma County, look for hotels and other accommodation in Rohnert Park. Rohnert Park has rooms for a wide range of budgets as well as car hire and transport links.
