The Lowdown
Alright, let’s unpack this one. I’m Rusty, and I’m telling you, the next week and a half at Avalon-South (Avalon) is gonna test your patience. You’re looking at a solid blank run until things finally wake up around Friday, August 14th – and that’s your one true standout.
From now through to the 12th, it’s mostly tiny, knee-high slop. Swell heights are mostly under 2 ft, with combined wave energy barely hitting double digits – weak stuff. The wind lays down nicely at times, with light offshore or glassy conditions, but there’s simply no power in the water. Clean, but flat as a pancake.
There’s a small bump on the 11th that’s “surfable but very ordinary” – about 3 ft from the ENE with light offshore wind. Energy is still weak (94). It’s not worth rushing out for, but it’s the first pulse in a week.
Now for the big one. Friday, August 14th, we get a solid pulse from the SSE pushing 10 ft in the morning (combined energy at 1313 – that’s legit). Winds are light offshore, keeping it clean. This is the pick of the whole outlook. But at 10 ft, this is for experts only. If you’re not experienced, give it a wide berth.
The afternoon drops to 8 ft and the wind swings cross-shore, so it’ll get a bit rough. The SSE swell has a 9-second period – short enough to keep it fun on most beaches.
Saturday the 15th holds at about 6 ft from the SSE, clean again in the AM with light offshore winds. Energy sits at 415 – moderate. Good for a strong surfer, but no match for Friday.
Sunday the 16th, morning looks decent: 6 ft from the SE, clean cross-off breeze with light rain, energy at 493. The afternoon gets messy with showers and onshore wind, so make your move early.
Water temp is 64°, which is right on average for this time of year. Nothing unusual there.
And a heads up – Avalon-South is beginner-friendly but often gets busy. The size and conditions in the second week will keep most beginners onshore, so you might have a bit more space.
Bottom line: the first 10 days are a total drought. The real deal hits August 14th and 15th – if you’re up for it, that’s your window.

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