The Lowdown
Alright, Rusty here, let’s talk about what’s happening on the ground over the next couple of weeks.
This stretch is a bit of a slow-burner for Dominical. We’ve got a run of small, clean, glassy mornings that will be a treat for the longboard or a fun mid-length, but nothing that’s going to get the heart rate pumping. The real standout sits right at the end of the lineup, so patience is key.
The ocean is pretty relaxed to start. Tuesday morning, the 15th, we’ve got a tiny 1ft swell from the southwest, but it’s glassy with no wind, so if you’ve got a log, get out there. The water is 86°, a touch warmer than normal for this time of year, so no need for a wetsuit. There is very weak wave energy (265) early on, but that’s fine for a cruise. Wednesday morning the 16th looks similar, with 2ft and glassy conditions again – real peaceful.
A bit of a dip hits Thursday the 17th, with onshore wind and poor conditions in the morning, so give it a miss. Friday the 18th bounces back to glassy 2ft in the a.m., but the afternoon gets a bit of a cross-onshore texture. Saturday the 19th is back to glassy 1ft in the morning with a long 19-second period, but that’s a lot of wait between sets for such a small wave.
The following week holds more of the same clean but small mornings, with a fun little bump on Monday the 21st – 2ft, glassy, and moderate energy (423). Tuesday the 22nd also looks tidy with calm, glassy conditions in the afternoon.
Now here’s the highlight: Friday morning, September 25th. That’s the one to circle on the calendar. We get a pulse of 6ft from the west-southwest, with glassy, calm winds and strong wave energy (584). That’s a solid overhead day for the advanced crew, and at that size it’s getting a bit much for beginners. That’s the pick of the whole window. The swell period is a short 9 seconds though, so it won’t be as lined up as a long-period groundswell, but with clean conditions, it’s going to be all-time for Dominical.
After that, Saturday the 26th and Sunday the 27th taper back to 3ft to 3ft, still with plenty of glassy windows in the mornings. The last few days of the month have small but surfable waves, mostly in the 3ft to 4ft range, with some glassy moments. Overall, the first week is small but clean, the second week has that one bomb on the 25th, and then it settles again.
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.
