The Lowdown
Hey guys, Rusty here again. Looking at this 16-day run for Three Peaks, I gotta be straight with you – it’s a mixed bag of frustration and a single moment of magic. There are big quiet spells, and you’re gonna have to be patient.
The first week is basically a no-go. From Monday the 7th through Sunday the 13th, the conditions are just awful. We have some decent height, with waves up to 6ft on the 7th and 6ft on the 8th, but the combined swell energy is moderate to strong (1540 at its peak). The problem is the wind. It’s blowing onshore or cross-onshore the whole time, turning everything into a choppy, bumpy mess. Not the kind of day you want to be wrestling a rental board.
We get a slight flicker of hope on Friday the 11th. The morning shows a clean cross-offshore wind and a 5ft swell from the west-southwest at 9 seconds. The energy is moderate (288). It’s clean, but it’s still a marginal call. Maybe a quick session for the dedicated crew.
Then it gets quiet again. From Saturday the 12th to Tuesday the 15th, we’re back to poor surf with onshore winds. The 16th offers glassy conditions with the wind going flat calm in the afternoon, but the swell is a tiny 2ft with very weak energy (74). It’s clean, but you're going to be doing a lot of floating.
The standout is Sunday the 20th. The afternoon session is the real gem. You’ve got a clean 4ft swell out of the west with a nice long period of 11 seconds. The combined swell energy is solid at 302. The wind is light and cross-offshore from the southeast, and the water is an incredibly warm 66°, which is way above average for this time of year. This is the one to aim for. Expect clean, lined-up waves with some punch.
After that, it drops off sharply into flat, tiny surf for the rest of the month. A long wait, but that one afternoon on the 20th has me humming.
Keep the faith, but don't rush out for the rest of it.
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.
