The Lowdown
Alright, let’s talk Three Peaks in feet and miles per hour.
First week’s a bust, plain and simple. From Wednesday the 9th through to Sunday the 14th, it’s mostly onshore junk. Water temp is 66°F, which is much warmer than normal – we’re talking about 5°F above the long-term average, so it’s properly toasty. Swell’s small, winds are from the SW and SSW, and the combined energy numbers are mostly in the double digits – weak. Friday the 11th morning offers a glimmer: a 5ft WSW swell, 9-second period, with light cross-shore wind. Still only marginal, but it’s the best of a bad lot early on.
Tuesday the 15th afternoon goes glassy with a 4ft SW swell, but only 98 combined energy – enough for a fun little clean wave if you’re keen, but nothing to write home about.
Now for the one that matters: Wednesday the 16th. That morning we’ve got an 8ft W swell, cross-offshore wind from the north, and the combined energy hits 930 – that’s strong. The afternoon stays clean with a 8ft swell and 716 combined energy. This is the standout. That size is big – over 8ft is expert territory, so it’s not for beginners. The period’s a bit short at 9 seconds, but the power is real. Crowds can show up here sometimes, so be ready for it.
After the 16th, it fades fast. Thursday the 17th back to onshore dribble, and the rest of the outlook is mostly small, choppy, or onshore. Friday the 18th morning goes glassy with a 1ft wave – barely a bump.
Bottom line: Wednesday the 16th morning is your only real shot at something worth paddling for. The rest is a long quiet stretch.

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.
