The Lowdown
Alright, Rusty here, let’s talk about what’s shaping up for Dominical.
We’ve got a solid run of surf ahead, folks, stretching right through the 16-day window. The overall pattern is one of steady, clean mornings giving way to afternoons that get a bit messy, but the mornings are where it’s at. The water’s a touch warmer than normal for this time of year at 86°.
First up, Friday the 28th of August is a ripper start. Dominical is showing 2ft of swell from the SW, but don’t let that small number fool you. The period is a very long 15 seconds, meaning real groundswell energy. The combined energy is a solid 404 (moderate). What makes this a standout is the glassy conditions in the morning, with barely a whisper of wind from the SSW at just 3 mph. It’s going to be clean, lined up, and that long period will wrap nicely into the point. The crowd factor is just “sometimes,” so you might actually get some room. This is the pick of the early window.
Saturday the 29th and Sunday the 30th see the swell picking up to 3ft, but the wind goes cross-on, putting a bit of texture on the face. Still rideable, but that Friday is the gem.
We hit a bit of a flat spot from Tuesday the 1st of September through to Thursday the 3rd, with swell dropping back to 2ft – 2ft. The energy drops right off (down to 204 on Thursday morning). Not worth paddling out for.
Now, hold onto your board, because from Friday the 4th of September, things get interesting again. The forecast shows a new pulse of SW swell building. On Friday morning, we’re looking at 3ft with a 17-second period and glassy conditions. The combined energy jumps to 711 (moderate). That’s a proper morning session. Saturday the 5th is even better: 4ft of SW swell, 16-second period, and again, glassy in the morning. Energy is up at 802. This is the standout of the entire outlook for me. The waves will have some push, but at 4ft it’s still manageable for strong intermediates. It’s a very good prospect.
Sunday the 6th keeps the run going with 4ft and glassy conditions, energy at 501. Through the rest of the second week, the swell stays in that 2ft to 3ft range, but the good news is that most mornings are glassy or very light offshore. The periods stay in that sweet 14–18 second groundswell range. It’s not pumping, but you’ll get clean, fun waves on most mornings right up to Saturday the 12th of September. That long-period swell at Dominical means the waves will have good shape and more energy than the height suggests, so look for the sets.
The afternoons all come with that risk of thunderstorms and a cross-onshore breeze, so early sessions are the rule. Get out there before lunch.
Rusty.

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.
