The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Conchalio over the next couple of weeks.
It’s a bit of a slow-burner to start, but there’s some real gold waiting for us if we’re patient. The first few days are small, but the mornings are the key. We’ve got a run of glassy conditions with clean, light winds that will make the most of what’s on offer. The water is sitting at a warm 86°, which is about average for this time of year, so no wetsuit needed.
The real standout arrives on the morning of Saturday, 29 August. That’s the one to circle on the calendar. We’re looking at a solid 5ft SSW groundswell with a very long period of 17 seconds, and the combined energy is pumping at 1306. That’s a serious amount of juice. The wind is dead calm, glassy as a mirror. This is for experienced surfers only – it’s too big for beginners. The long period means the waves will have real power and shape, and the sets will be spaced out, making the paddle out a bit easier. The morning of Sunday, 30 August is a close second, with another 5ft SSW swell, also glassy, with energy at 1024. That’s another cracker for the experienced crew.
Before that, the best of the smaller stuff is the morning of Saturday, 22 August. A clean 3ft S swell, glassy conditions, and decent energy (434). It’s a great session for a log or a funboard. The mornings of the 19th, 20th, 21st, and 23rd all offer clean, glassy windows with knee to waist-high waves, but the 22nd has a bit more push.
After the big weekend, the swell drops but stays rideable into the first week of September. The mornings of Monday, 31 August and Tuesday, 1 September are still very good, with 5ft and 4ft SSW swells respectively, and glassy conditions. The crowds are listed as “sometimes,” so you might have some company, but it won’t be a circus.
There is a gap of a few days in the middle of the second week where the afternoons get chopped up by onshore wind, but the mornings consistently deliver clean waves. The late-season pulse on the 29th and 30th is the real deal.
Rusty out.

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.
