The Lowdown
Alright, let’s break this down in feet, for those who think that way. This is Rusty, and Dumps is looking at a mixed bag that’s got some absolute gems.
The first few days are solid, but the real highlight is Monday, August 3rd. That morning, Dumps gets a clean 4ft SW groundswell with a 14-second interval and glassy conditions. Combined wave energy is 1170 (moderate energy) and the shape should be really good. The afternoon is just as sweet, 6ft SW swell, 13 seconds, still glassy, and energy at 1147. That’s your best call early on.
Now, Dumps can be a little inconsistent, but when it fires, it’s worth it. Water temperature is nothing unusual, right around the seasonal average.
Watch out: Wednesday, August 5th, the swell jumps to 12ft SW with a 14-second period and energy at 4618 – that’s expert territory. The wind is onshore and messy, so leave that one alone.
Coming into the second week, Thursday, August 6th has a morning that’s excellent for pros: 10ft SW swell, 16-second period, glassy, clean, and energy at 5084. That’s a proper long-period groundswell. It’ll be fast and powerful, best for a reef or point, but Dumps can work if the tide helps. Crowds are possible, but on a day that size, it’ll be quiet.
Friday, August 7th is another standout for the experienced crew – 10ft SW dropping to 8ft in the afternoon, glassy to clean cross-off winds. Top shelf.
There’s a rough patch from the 9th to the 10th of August with wind ripping at 25 mph, making a mess of it. Swell is still hefty, but quality is shot. That’s more kite territory.
Things calm down by Tuesday, August 11th afternoon, with a 7ft S swell and glassy conditions. And the good run looks to continue to Saturday, August 15th morning, where you’ve got 8ft WSW swell, dead calm, glassy, and energy at 1496. Another cracker for the experienced surfer.
So to sum it up: Dumps has a few real winners, especially Monday, August 3rd for all-round fun, and the 6th, 7th, and 15th of August for the more advanced. There are gaps of windy, messy days, but the good ones are well worth waiting for.
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.
