The Lowdown
Alright mates, Rusty here. Let’s break down what’s coming our way.
We’ve got a big SW groundswell hitting Dumps right now. Monday the 27th into Tuesday the 28th, we’re seeing waves 10ft to 12ft with a very long 17-second period. Wave energy is massive — over 13,000 in the arvo. Not for beginners. The wind is cross-off from the SSE so the surface will be clean, but this is strictly for experts. Water temp is about normal for this time of year. The long period means the waves will pack a punch and dump hard on the sandbar.
Tuesday the 28th, the swell drops to 8ft with 14 seconds, and we get offshore wind from the SE in the morning, shifting ESE later. Clean conditions and excellent shape — another good window for strong surfers. Energy is still well over 2,000.
Wednesday the 29th to Thursday the 30th, size comes down to 5ft to 6ft, still SW and 13-second period. Light cross-off winds. Much more doable for intermediate surfers looking for a clean wave. Energy is moderate, under 1,000 but still punchy enough.
Friday the 31st, it’s small — 3ft to 4ft with light winds. Not a lot of push but glassy surface. Good for a small-wave board.
Saturday the 1st of August is the standout. Morning offers 5ft SW swell with 14 seconds and light cross-off wind. But the afternoon goes glassy — dead calm wind, and clean 4ft swell. This is the best window for the average surfer in this whole outlook.
From Sunday the 2nd onward, things get rough. Swell jumps to 8ft but with choppy north and northwest winds. Poor surf. Monday the 3rd stays messy with cross-shore winds and lumpy conditions. Crowds are sometimes a hassle here, so not a great time to be out.
Into the second week, Thursday the 6th to Saturday the 8th of August, we see another huge swell — 10ft to 13ft with 15-second periods. Energy readings over 5,000 and even 6,000. The wind is light and cross-off or even glassy at times — but the size is simply too much for this spot. Only for expert big-wave chargers.
From Sunday the 9th into Monday the 10th, it’s onshore and messy. Tuesday the 11th morning still looks marginal, but by the afternoon there’s a small 5ft SW swell with cross-off wind and a short 8-second period — might be rideable but nothing to write home about.
All in all, Saturday the 1st of August is the one to circle — especially that glassy afternoon session. Everything else is either huge and dangerous or small and choppy.
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.
