The Lowdown
Alright, Rusty here, and I’ve got a solid 16-day look at the waves for us. Let’s get into it.
We’ve got a good run of surf on the cards. The pattern is built on consistent SW groundswell, with a few standout days where the ocean really turns it on. The water’s sitting at 86°, which is about average for this time of year, so no surprises there.
First real action kicks off Friday morning, August 28th. The swell is a clean 3ft from the SSW, with a serious 16-second period – that’s proper groundswell energy. The wind is glassy out of the NNE, and the wave energy is moderate (636). For a beginner-friendly spot like Conchalio, this is a lovely, mellow start. The morning will be clean and fun for a longboard or a foamie. The afternoon goes onshore, so make sure you’re out early.
Saturday morning, August 29th, is the first of our real standouts. The swell bumps up to 5ft from the SW, still with 16 seconds on it. The wind is dead calm – glass – and the combined energy is strong (1076). This is where it gets good for more experienced surfers. The waves will have punch and shape. If you can handle a bit more size, this is your morning. The afternoon gets onshore, so it’s a morning mission.
Sunday morning, August 30th, offers another excellent session. The swell holds at 5ft from the SW, period drops a touch to 14 seconds, but the wind is glassy from the ENE. Energy is still solid (807). It’s very good, clean surf. The swell direction from the SSW is a good match for Conchalio’s exposed setup.
Monday and Tuesday mornings (Aug 31 & Sep 1) keep the clean conditions rolling with smaller swells around 4ft and 3ft, glassy winds, and manageable energy. Good for the beginner to intermediate crew.
Looking further out, the first week of September brings a late pulse. Wednesday morning, September 2nd, has a smaller 2ft swell but with a very long 18-second period. That’s straight-up groundswell, which can make for some nice, lined-up waves at Conchalio even with less height.
Then we get a solid weekend run. Friday morning, September 4th, is the absolute pick of the second week. The swell is 5ft from the SW, period is 17 seconds, and combined energy is very strong (1336). Wind is glassy from the SE. This is a serious session for experienced surfers. Clean, powerful, and consistent.
Saturday morning, September 5th, is another big one – 6ft from the SSW with 16 seconds and strong energy (1376). Glassy conditions. This is expert territory for sure. It’s big, long-period swell that will be best handled by someone with experience. If you’re not confident, save yourself for the smaller days.
The rest of the second week backs off slightly but stays fun, with mornings generally glassy and swells in the 3ft to 4ft range. There are no long flat gaps here; it’s a consistent stretch. Just keep an eye on the risk of thunderstorms in the afternoons after the 3rd of September.
Best on offer: Saturday morning, August 29th for a big, clean session, and Friday morning, September 4th for the best of the longer-range swell. Both are standouts with glassy wind and strong, long-period SW swell.

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.
