The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaking at Conchalio. This spot is exposed to the west, and we’ve got a solid run of south-west groundswells lining up. The water’s sitting at 87°, which is a touch warmer than normal for this time of year – nice for a long session.
Thursday morning (3rd) is where we kick off. It’s glassy, dead calm, with a 3ft SW swell at 16 seconds. That’s proper long-period groundswell, so you’ll feel the energy pulling through. The combined energy is moderate (725). For a beginner-friendly break, this is a clean, easy entry into the forecast.
But Friday morning (4th) is the real standout. The swell jumps to 5ft from the SSW, period still a lovely 17 seconds, and it’s glassy again. The combined energy is strong (1366). That’s excellent surf for experienced surfers, but at 5ft it’s still manageable for a confident intermediate. The wind is calm, the waves will be lined up, and the crowd factor is only “sometimes” an issue here, so you’ve got a good chance of a peaceful session.
Saturday morning (5th) is another beauty. Swell is 6ft from the SSW, period 16 seconds, glassy conditions. This is getting into the “too big for beginners” territory, but for the experienced crew, the combined energy of 1390 means plenty of push. The wave direction is a great match for the break’s optimum west swell, so expect some nice, peeling lines.
Sunday morning (6th) is still very good, with 5ft SSW swell, 15 seconds, and glassy. The energy drops a bit to 969 (moderate), but it’s still clean and fun.
Monday (7th) and Tuesday (8th) mornings hold on with glassy conditions, but the swell drops to 4ft and 2ft. The periods stay long, so the quality is still there, just smaller.
After that, there’s a bit of a lull for a few days. The mornings on Wednesday (9th) and Thursday (10th) are still glassy with clean, small waves (3ft to 3ft), but the afternoons get blown out with onshore winds.
Friday (11th) morning is worth a mention – glassy, 4ft SW at 16 seconds, very clean. Then the next week sees a string of mostly glassy mornings, but the swell size stays modest, mostly under 3ft.
The real sneaky standout comes on Thursday, 17th September. The morning is glassy, and the swell is only 2ft, but the period is a massive 24 seconds. That’s very long period groundswell. The combined energy of 873 is moderate, but with that period, the waves will be super clean, very lined up, and the sets will be spaced out. For a point break or reef, this would be a dream, but at a beach break like Conchalio, it might be a bit too straight. Still, for the experienced surfer, that’s a fascinating morning to check.
Overall, the best bet is Friday morning, 4th September, for the best combo of size, period, and glass. Saturday morning, 5th, is the biggest and still clean. Beyond that, the mornings are your friend – the afternoons mostly get wrecked by onshore wind.
Stay stoked, catch you in the water.

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.
