The Lowdown
Alright, this is Rusty. Let’s have a look at what’s coming up for Three Peaks over the next couple of weeks.
Right off the bat, I gotta be straight with you: there’s a long, painful stretch of nothing happening. From now through most of the month, it’s a real write-off. The first sign of something worthwhile doesn't show up until the first week of September, and even then, it’s not until the very end of the window that we get a proper pulse.
For the rest of August, the swell is tiny and the wind is mostly onshore or cross, making a mess of things. We get a bit of a bump around the 19th and 20th with swell pushing up to 6ft from the west, but the wind is howling fresh cross-onshore at 19 to 22 mph, and the wave energy is moderate at best (427 on Thursday morning). That’s a lumpy, choppy mess – more of a kite-surfing day than a paddle session. The water temperature is a balmy 21°, which is much warmer than normal for this time of year, but that doesn't help the surf quality.
The real standout, the one that gets my heart pumping, is Monday, August 31st. The morning shows a clean 7ft west swell rolling in, with light cross-offshore winds from the east-southeast at just 6 mph. Wave energy will be very strong (725), and conditions look glassy and clean. That’s a proper groundswell with an 8-second period, which is a solid combo for a beginner-friendly break like Three Peaks. However, at 7ft, it's on the upper edge for beginners, so know your limits. Crowds are sometimes an issue here, so get in early.
A secondary, less certain shout goes to Friday, August 28th. The morning has a clean 6ft swell from the west-southwest with light cross-off winds, giving it a good look. The energy is strong (294), and it's a nice lead-in to that bigger Monday. The period is short at 7 seconds, so the waves will be a bit softer and more crumbly than that later pulse.
So, if you can hold out, the end of the month and the start of the new one is where it's at. Everything before that is a waiting game.
Stay keen.

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.
