The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the menu for Dominical. We’ve got a solid run of clean, small-groundswell energy coming in over the next couple of weeks, so this isn’t a storm-chaser’s forecast, but it’s a beauty for the longboarders and anyone who loves a clean, long ride.
The first few days, starting Monday, August 10th, are all about a glassy, clean ocean. The swell is small, around 2 ft, but it’s a long-period groundswell from the SW, with a period of 13–14 seconds. That’s proper, lined-up energy, even if it’s small. The combined energy is moderate, sitting at 248 (moderate wave energy), and with the wind barely a whisper, the morning sessions are going to be absolutely perfect. The water temp is about average for this time of year, so no need for a thick wetsuit.
The real standout in this first week is the morning of Friday, August 14th. The swell jumps to 2 ft but the period stretches to 18 seconds, and the energy jumps to 426 (strong to very strong wave energy). The wind is glassy – that’s the best you’ll see. The waves are going to be long, clean, and a joy to ride. It’s a long-period groundswell, which means it might break a little too straight at the beach break, but on a good tide, it’ll be world-class for a point or rivermouth.
The second week looks more of the same: small but consistent. The morning of Monday, August 18th, is another pristine glass-off with the wind dropping to zero. The swell is 3 ft from the SW, period around 14 seconds, and the energy is 343 (moderate wave energy). It’s a repeat of the same clean, small-wave formula. The morning of Saturday, August 22nd, also has glassy conditions and a little more energy at 313 (moderate wave energy), with a clean 3 ft SSW swell.
The water temperature stays pretty much average for the whole run. No weird anomalies.
Now, the crowds. Dominical is an exposed spot, and it’s a popular one. The guidance says crowds are “sometimes” an issue. With this kind of clean, small, long-period swell, expect a few more friendly faces in the lineup, especially on the weekends. If you want a bit more peace, the early mornings with that glassy wind are your best bet.
Overall, this is a solid run for the small-wave enthusiast. The best of the best is that Friday morning, August 14th, and the Monday morning, August 18th. Don’t expect any big grinding barrels, but if you want a smooth, clean glide, it’s on.
Rusty out.

Information about the Dominical Surf forecast
The above surf forecast table for Dominical provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dominical can be found by selecting the local surf guide option on the grey menu. Our Dominical 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 (Dominical) 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 Dominical 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.
