The Lowdown
Alright, listen up. Rusty here. I’m not gonna sugarcoat it: the next sixteen days are a total dud for surf. There’s a big old flat spell staring us right in the face, so if you’re looking for waves, you might want to pick up a paddleboard or learn to love the lake. We’re looking at a solid gap with nothing on offer.
The first time we even see something that’s worth a mention is on Wednesday, August 26th, early. It’s small, but there’s a bit of south swell at 5ft with a 12-second period. The combined energy is moderate at 761. It’s a light cross-on breeze, which will put a bit of a crinkle on the surface. It’s marginal, at best, so don’t go rearranging your schedule. Water temp is a balmy 72°, a solid 5° above where it should be this time of year. That’s a big deal.
After that, it’s just a slow grind of tiny, weak surf. We’re talking waist-high slop through the end of the month. The period gets long, like 19 seconds on Friday, but with only 2ft of swell, it’s a tease. The energy is there but the size isn’t. It’s all just messy and uninspiring.
The first week of September keeps the same story: small south swells, 3 to 4ft, with light winds in the morning. It’s technically surfable, but the forecast keeps saying it’s poor or marginal. There’s no punch, no push. Just a lot of bobbing around.
Now, about that one bright spot. It’s a long way off, but on Wednesday, September 9th, in the afternoon, the ocean wakes up. The swell is forecast at 7ft from the south with a 16-second period. The combined energy is a very strong 2618. That’s the whole ballgame right there. This is a serious, expert-only wave. Anything over 8ft is too much for beginners, and this is right there with a long-period groundswell. At a beach break like Surfside Jetty, that long period can make it close out and look pretty gnarly. The wind is a cross-on 20 km/h, so it won’t be glassy, but it’ll have power. This is a promise for the future, but it’s a long way out, so take it with a grain of salt.
So, there you go. A whole lot of flatness and then one big, far-off storm swell to dream about. Don’t sell your board, but maybe start planning a road trip or tune up your gear. Forecasts change, so this blank run might not last forever. I’m Rusty, and I’m out.

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