The Lowdown
Alright, Rusty here. Let's break it down for Three Peaks over the next couple weeks. It’s a slow start – hardly any surf to speak of for the first few days. We’re looking at a gap of flat, weak conditions before anything worthwhile shows up.
Things perk up a little on Thursday morning, the 20th of August. Swell comes in around 5ft from the WSW, but there’s a cross-shore wind at 12 mph making it lumpy. By the afternoon it cleans up with a cross-off breeze and a 5ft W swell. Still, it’s not a standout.
Friday the 21st stays clean but tiny, with waves around 2-2ft, light winds, and cross-off conditions. Clean but small. The weekend gets even smaller – Saturday the 22nd has 1ft waves, clean but flat. By Sunday the 23rd it’s almost glassy but with next to no swell. A long, slow stretch for a spot that breaks pretty consistently.
The real highlight is the afternoon of Saturday, the 29th of August. We’ve got a 5ft swell from the WSW, clean as a whistle with a light cross-off breeze, and combined energy coming in at 247 – moderate, solid for the break. The swell direction lines up well. This is the best on offer. Crowds can be a thing here, so keep that in mind. It’s over a week out, so plenty of time for the forecast to finesse, but it’s looking good.
Sunday the 30th gets bigger – 8ft from the W by the afternoon – but the wind picks up to 19 mph, making it lumpy and rough. Not a beginner’s wave. Then Monday the 31st of August sees a monster 12ft swell from the WSW with energy off the charts (2248). That’s way too much for Three Peaks – expert only, with strong cross-shore wind making it a messy beast.
After that, the first week of September drops off with moderate swells and poor, choppy wind. Nothing worth chasing.
So, here’s the call: the first week is mostly flat. The best bet is that Saturday afternoon, the 29th of August. Clean, fun-sized, and lined up right. Everything else is either too small or too ugly.
Rusty.

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