The Lowdown

Alright, Rusty here again, switching to feet and miles for the imperial crew.

We've only got one spot on the radar for this 16-day stretch: Dumps. It's a sandbar set-up that doesn't fire all that often—let's just say it's an inconsistent little number. But when the stars align, it can offer up some clean, punchy wedges. The water temp is about average for this time of year, nothing too crazy.

The window opens Friday morning, August 21. That's the first real chance for a paddle. You're looking at a solid 7ft swell from the southwest, with a cross-off breeze keeping things clean. The energy is pumping with 1106 (moderate energy) and the 11-second period means decent shaped waves. It's a good start, but it gets better.

The real standout here is Sunday, August 23. The morning session is the pick of the first week. We've got a 7ft to 8ft swell from the west-southwest, cross-off wind all day, and a long 13-second period that will put some serious grunt into the waves. The combined energy jumps to 1667, which is getting into that strong zone. This is excellent surf for experienced surfers—well overhead, clean, and packing a punch. It's likely to be a favourite with the crew, so expect it to be 'sometimes' busy.

After that, Tuesday, August 25 morning is another cracker. A 8ft southwest groundswell with a 14-second period—that's very long period, so expect long lines and long lulls. The energy is strong (2157) and the offshore wind is perfect. This is proper jetty-level juice, but the long period might make it stand up a bit walled at the sandbar; still, for the experienced crew, this is a top morning.

There are a few other clean mornings in there—like Wednesday morning with a 5ft swell and offshore wind, and the 31st with glassy conditions—but nothing that dials it up like the 23rd and the 25th.

Now, a big warning: from Thursday, September 3, the swell absolutely hammers in. We're talking 16ft plus from the southwest, with combined energy up over 10,000. That's way, way too big for Dumps. The setup looks more interesting for kite surfing than paddle surfing at that size. Even if the wind is clean, that's a beast only for the very brave (or the very stupid). The 5th of September still has an 8ft swell but with a cross-on wind, so it's messy.

So, to sum it up: the first week has the goods, especially the 23rd and 25th. The second week gets massive and then messy. Don't sleep on the early window.

Rusty.

Information about the Dumps Surf forecast

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