The Lowdown
Right, let's have a look at what’s cookin’ for the Dumps. This spot’s a sandbar set-up, so it can be a bit fickle. It's inconsistent by nature, which means you gotta pick your moments, but when it lines up, the Dumps can give ya something special. For the first week or so, it's looking like a solid run of clean, manageable surf, for the experienced crew. The water temp is sittin' about average for this time of year, so no surprises there.
This Tuesday morning kicks things off with a solid SW groundswell at 8ft, pumping at a very long 14 seconds period. That’s a real power surge, with a combined swell energy of 2509 – strong and pushing hard. It’s got a moderate offshore breeze from the SE, so that sandbar is gonna be clean and shapely. This is expert territory though, anything over 8ft gets serious, especially with that kind of energy. Tuesday afternoon stays excellent, same swell, just a tad smaller at 8ft, with lighter offshore wind. For the experienced surfer, Tuesday is a real highlight.
Wednesday the 29th drops a notch to a very clean 6ft from the SW, still a long 13-second period, with light cross-offshore breezes. It’s not the biggest but it’s a good fun size for a bigger range of surfers. Thursday the 30th is a real gem. We’re talking 5ft to 5ft SW swell, long period, but the wind goes glassy. That’s the best-case scenario for clean waves, and the combined energy is moderate at 809 and 732. It’s a good day for anyone to get amongst it.
Friday the 31st through Saturday the 1st, the swell backs off to 4ft to 4ft with glassy conditions. It’s on the smaller side for the Dumps, but clean as a whistle. It’ll still produce some fun little waves for mellow sessions, but the energy drops (484-595), so nothing to shout about.
Sunday the 2nd is a bit of a mixed bag, with a glassy afternoon that bumps the waves back up to a clean 4ft. Worth a look maybe.
Now, here’s where it gets interesting again. Monday the 3rd of August. Boom. A new SW groundswell hits, 8ft at 14 seconds, glassy conditions in the morning. The combined energy shoots up to 2321. It’s right on the edge of expert territory but morning glass is a massive plus. Tuesday the 4th doesn't look great with onshore winds.
But then, Wednesday the 5th is a cracker. 8ft of SW groundswell, a very long 14 seconds, glassy, moderate energy (3567). This is another proper window for experienced surfers before things start to get a bit too big.
From the afternoon of the 5th into Thursday the 6th, the swell really maxes out, hitting 12ft to 13ft, with very strong energy (4319-5975). At that size, the Dumps is one for specialists only, and the afternoon winds turn onshore, which makes it look more like a kite-surfing setup than a paddle one. The swell is predicted to be too big for this break for standard surfing on those afternoons.
The second week stays mixed. A new swell arrives around the 10th, but it’s 10ft to 12ft again, solid but likely too big for the sandbar to handle with the best shape, despite clean winds. The 12th of August closes out with another 10ft SW swell with glassy to gentle offshore breezes – another expert-only final hurrah, but with crowds possible at a spot that's inconsistent by nature.
To be honest, the real standouts here are the glassy mornings on the 30th of July and the 5th of August, with the 3rd of August morning also a top pick for the experts. Those are your go days. Outside of that, there's a few smaller, clean windows, but the Dumps is really about those quality pulses.

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.
