The Lowdown
Alright, Rusty here. Let's chew the fat on what Three Peaks is offering up for the next couple of weeks.
First thing’s first—this is a lean stretch. We’ve got a full 16-day window, but there’s not a whole lot that’s gonna get you out of bed. The first week especially is a grind, with messy winds and mediocre conditions hanging around.
We kick off Tuesday, September 8th, and it’s a tough start. The water’s sitting at a warm 65°F, which is a few degrees above normal for this time of year—you might be ditching the steamer. The surf? Cloudy, cross-shore winds at 16 mph, and a scrambled 6ft swell from the WSW. The energy is moderate (528), but the quality is poor. Things stay ragged through Wednesday and Thursday. By Thursday afternoon, we get a bump to 6ft from the SW, but it’s onshore and lumpy—not your friend.
The first real glimmer shows up on Friday, September 11th, in the morning. A clean, cross-offshore wind from the NNW at 12 mph cleans things up. Swell drops to a tidy 5ft from the WSW, with a 9-second period. The energy reads solid (337). It’s not perfect, but it’s the pick of the week by a long shot. Still, it’s a marginal call at best.
After that, we hit the doldrums. From Saturday, September 12th, all the way through to Tuesday, September 22nd, the swell barely gets above 2ft. Winds are all over the place, and the energy drops to the low double and triple digits. There are a few clean, glassy patches—like Thursday afternoon, September 17th (1ft, glassy) and Friday afternoon, September 18th (1ft, glassy)—but there’s just not enough water moving to bother. Those are rest days.
The second week offers a faint hope on Saturday, September 19th. Morning is clean with a light offshore breeze and 1ft from the W. Tiny, but tidy. Monday, September 21st, also shows a 12-second period swell at 1ft from the WSW. That long period gives it a bit of push for a wave that size, but you’d still need a log and low expectations.
Honestly, there’s nothing here that screams standout. The Friday morning on the 11th is your best bet if you’re itching. Everything else is for the patient or the longboarder. Forecasts can change, so keep an eye out.
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.
