The Lowdown
Alright folks, Rusty here, and I’ve been staring at the charts for our patch. Got a pretty solid run of surf coming through for Playa-Conchalio. It’s not one of those explosive, all-or-nothing swells, but we’ve got a decent, drawn-out pulse of groundswell that’s going to deliver some clean, rideable waves for the next couple of weeks.
The water is sitting around 86°, which is about a degree and a half warmer than usual for this time of year – feels nice and balmy on the skin.
First up, the real standout and the one to circle on your calendar is Friday the 4th of September. We’ve got a solid 5ft of SW swell (moderate-to-strong energy at 1412) with a classic 17-second period. That’s proper groundswell, meaning it’ll bend around and wrap in nice and steady. The real kicker here is the Friday morning session: glassy conditions, zero wind. It’s going to be clean as a whistle. That one is for the experienced crew – 5ft with that power is proper.
We roll into Saturday the 5th of September with the biggest swell of the window – 6ft from the SSW. That’s expert territory. Again, the morning window is glassy, and the energy is strong at 1378. If you’re a confident surfer, that Saturday dawn patrol is going to be pumping and very, very clean.
The week prior starts off mellow. Monday the 31st of August kicks off with a clean, glassy 4ft SW swell (471 energy, 13s period). That’s a nice little warm-up. The afternoons through the week get messed up by onshore breezes, so stick to the mornings.
Wednesday the 3rd of September morning is another glassy gem – 3ft of super-long period 16-second SSW swell. It’ll be small but silky. The long period will make it peel nicely for a beginner-friendly wave.
There’s decent groundswell holding into the second week. Monday the 7th of September morning has a clean 4ft (14s) swell, and Tuesday the 8th morning is dead calm with 3ft (13s). From Wednesday the 9th through Friday the 11th, the mornings are all glassy with waist-to-chest high waves and that lovely, long period. That Saturday the 12th of September is a glass-off too, with a clean 3ft of SW swell.
If you can only paddle out for one session, make it Friday the 4th of September morning. For a close second, that Saturday the 5th morning for the bigger, more powerful stuff. The rest of the time, the mornings are the ticket.
Rusty.

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