The Lowdown
Alright, Rusty here. Let’s have a look at what’s shaping up.
We’ve got a run coming in from the south-west that’s got some serious legs on it, but this spot, Dumps, is a sandbar and it's inconsistent, so don’t be expecting a non-stop party. It’s for the crew with a bit of experience under their belt.
The water’s sitting pretty average for this time of year, so nothing to write home about there.
The action kicks off on Sunday the 26th of July with a clean, glassy morning. The swell’s a solid 7ft out of the SW, with a period of 12 seconds and the combined energy is sitting at 1476 – that’s a moderate-to-strong push. It’s a bit on the bigger side, so this one’s for the experienced lot. The wind’s glassy, so the surface will be smooth as silk. Sunday afternoon holds up well, too, with a 6ft SW swell and a light cross-off breeze keeping things clean.
Monday the 27th sees the swell ramp up to 10ft in the morning with a very long 17-second period from the SW. The combined energy hits 4335 – that’s strong. This is a proper groundswell, and with that long period at a sandbar, it might be throwing some closeouts. The wind’s a moderate cross-off, so it’s clean, but this is expert-only territory. The afternoon stays big and windy.
Tuesday the 28th is the pick of the first week. Morning has a 8ft SW swell (14-second period, energy at 2232) and a clean cross-off breeze. Then Tuesday afternoon? That’s the standout: the wind flips to a gentle offshore from the ESE, and the swell holds at 8ft with a 14-second period. That’s textbook clean, lined-up waves. The combined energy is 2140 – strong but manageable for the right crew.
Wednesday through to Friday the 31st sees the swell ease back a bit, with 5ft to 6ft SW swells, still with decent 13-second periods. The wind stays favourable, mostly light cross-off or offshore, so there’s rideable, clean surf through that stretch.
We get a bit of a lull on Saturday the 1st of August. The morning is a bit messy with a cross-on wind, but by Saturday afternoon it goes glassy again with a 4ft 13-second SW swell – small but clean.
Now, hold onto your board. Sunday the 2nd of August is the big one. The morning is glassy, the swell jumps to 6ft but with a 19-second period from the SW – that’s as long as it gets. The combined energy is 2327. And then the afternoon? 8ft, 17-second period, glassy conditions, energy at 3005. This is a proper groundswell, best for a point or reef, but at Dumps it’ll still be powerful and clean. It’s the best on offer.
Monday the 3rd and Tuesday the 4th are chunky but the wind gets a bit onshore or cross-on, making it a bit of a wrestle. The swell hangs around 7ft to 7ft. Tuesday afternoon does glass off again, so that’s a window worth watching.
We get a run of clean-but-chunky days from the 5th to the 6th, with swell up to 10ft. The 7th and 8th of August, the swell explodes – 13ft to 15ft – and the wind is favourable, but at that size, it’s a washing machine at a sandbar. That’s kite-surf territory, not paddle.
The run finishes on Monday the 10th of August with a glassy 10ft groundswell from the W – strong energy at 2374 – but again, that’s a big wave for the experienced only.
Overall, the standout window is Sunday the 2nd of August, with the glassy, long-period SW groundswell. Tuesday the 28th of July is also a clean, solid day with offshore winds. The rest is inconsistent but has its moments.
Rusty out.

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.
