The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on offer for the next couple of weeks.
We’ve got a solid run of small but clean windows coming up at Conchalio. The water is sitting at 86°, which is a touch warmer than normal for this time of year, so you can leave the thick rubber at home. The standout period kicks off Thursday morning, September 10th. That’s the pick of the week. We’re looking at a 3ft swell from the SSW, with a long period of 17 seconds pushing in a solid moderate wave energy (930). The wind is glassy, ENE at 3 mph, so it’s going to be pristine. That’s the session to point the car towards.
Friday morning, the 11th, is another cracker. Similar story: 4ft from the SW, 16-second period, and glassy calm winds. Moderate energy there too (742). It’s a little more size, but it’s still very manageable for a beginner-friendly spot. The consistency is fair, and while crowds do show up sometimes, it’s worth it for those conditions.
The following week, things get a bit more interesting in size but trickier. Wednesday morning, the 16th, has a 4ft SSW swell with a 16-second period, glassy NNE winds, and wave energy reaching 998. That’s a strong pulse, and the glassy conditions will make it look better than the number suggests. But remember, this is a beach break with a long-period groundswell, so it might throw a few closeouts. Still, that morning is promising.
Later in the week, Thursday morning the 17th and Friday morning the 18th offer clean conditions again. The 18th has a 3ft SSW swell with offshore ENE winds at 3 mph, giving it clean, lined-up waves. Moderate energy there (571).
After that, we get a few more mornings of glassy or clean conditions, but the size stays small. Sunday morning the 20th has a 3ft SSW swell with 19-second period, offshore ENE wind, and moderate energy (571). That’s a long-period, small day, but it’ll be clean.
There are no real gaps with no surf on offer, but there are plenty of afternoons that go onshore and messy. Focus on the mornings. The best of the best is Thursday the 10th and Wednesday the 16th, with Friday the 18th as a solid backup.
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.
