The Lowdown
Alright folks, Rusty here. It’s gonna be a slow, steady run for Dominical over the next couple of weeks. Nothing huge, but there’s a nice, long-period groundswell pushing in from the southwest that’ll keep things rideable for those who know the spot. This is an exposed, advanced break, so the challenge is part of the draw, and with the water temperature sitting at 86° – a touch warmer than normal for this time of year – you’ll be comfortable in a spring suit or just boardshorts.
The action starts on Wednesday, September 9th, but it’s a bit of a warm-up. The morning shows a small 2-foot SW swell with a very long 16-second period, but the wind is cross-on from the south, creating a little bump. The combined energy is moderate at 305. That afternoon, the wind picks up onshore, so it’s not the best time to paddle out.
Things clean up nicely on Thursday, September 10th. The morning is glassy with a 2.3-foot SW swell and a beautiful 18-second period. The energy jumps to 492, which is solid for this size. The water is still that warm 86°, and the offshore conditions (glass) will make for some clean, lined-up waves. This is one of the better windows.
Friday, September 11th, keeps the good vibes going. The morning is glassy again with a 3-foot SW swell from 16 seconds (energy 458). The afternoon goes glassy too, with a slightly shorter period of 15 seconds. This is a solid day for a session.
The weekend rolls in with a bit of a mixed bag. Saturday, September 12th, has a light cross-on wind in the morning on a 2.6-foot, 14-second swell, but the afternoon turns glassy again with a 2-foot swell. The energy is dropping off to 264. Sunday, September 13th, is small and glassy all day, with 2-foot to 1.6-foot waves and energy down around 180. It’s surfable, but nothing to write home about.
The following week (September 14th to 19th) is a real mixed bag of glassy mornings and onshore afternoons, with swell sizes hovering between 1.3 feet and 2.3 feet. There’s a notable spike in period on Monday, September 14th, with a 19-second swell, but it’s only 1.3 feet, so the energy is just 210. It’s a waiting game.
The real standout, and the one to circle on your calendar, is the long-range call for Monday, September 21st, and Tuesday, September 22nd. The forecast shows a glassy morning on the 21st with a 2-foot, 18-second SW swell (energy 333), and the afternoon goes glassy too with a 2.3-foot, 18-second swell and energy building to 421. Tuesday morning, September 22nd, looks pristine: glassy winds, 2.3 feet from the SW, 16-second period, and a combined energy of 481. That’s the best energy of the whole window. It’s a bit far out, so keep an eye on it, but it’s got real potential for clean, long rides.
Crowds are a possibility at Dominical, especially on those cleaner days, so get in early. Overall, this is a run of small but consistent, quality groundswell. The best bet is the glassy windows on Thursday the 10th and Friday the 11th, with the long-range Tuesday the 22nd looking like a potential gem.

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.
