The Lowdown

Alright folks, Rusty here. Let's have a look at what we've got on the cards for Dumps.

Alright, so the run starts this Saturday, the 15th of August, and straight away Dumps is showing some serious grunt. We're looking at a solid 7ft groundswell from the WSW with a meaty 13-second period. That swell energy is pumping, clocking in at 1398, so there is plenty of water moving around. Water temp is sitting at 56°, which is a fair whack colder than what you'd usually expect for this time of year – over four degrees below, so bring the thick rubber. The wind is light out of the south, a nice cross-off, keeping it clean for the experienced crew. Dumps is an inconsistent sandbar, and it doesn't break all that often, so when it lines up like this, you get your skates on. With that size and power, this is expert territory, not for the faint-hearted.

Sunday morning the 16th is a bit of a write-off with a cross-on wind messing up the shape, and the afternoon looks onshore, so no thanks there. Monday the 17th is also looking messy with onshore and cross-on winds. Tuesday the 18th, however, is back on. Clean cross-off winds from the SSE, with an 8ft swell from the WSW and a 12-second period. The energy is massive at 2684. This is another day that is strictly for the experienced surfer, with powerful, chunky waves.

Wednesday the 19th keeps the good run going. Clean cross-off winds and a solid 8ft SW swell, energy at 1638. The conditions are set up for a proper session. Thursday the 20th holds similar quality, still in that 8ft to 8ft range with clean winds. But the absolute standout in this first week looks to be Friday the 21st of August morning. The wind goes glassy, dead calm out of the SE, with a 7ft SW groundswell (12-second period). The energy drops a bit to 1094, but that glassy surface will make for some silky, debatable waves. It's still big for a learner, but for the rest of us, it's a gem.

We hit a bit of a lull on Saturday the 22nd, with the swell dropping to 5ft and a messy cross-on wind making it a poor, choppy mess. That setup looks more like kite-surfing weather than a paddle session.

Sunday the 23rd brings back some fire. A clean, cross-off southerly and a 7ft to 7ft WSW groundswell that builds through the day. The afternoon sees the period stretch out to a very long 16 seconds, with energy smashing through 3278. That long period will wrap nicely into Dumps but might make it a little too straight for the soft beach breaks.

Now, hold onto your board shorts for this: Monday the 24th of August looks absolutely massive. A 10ft SW groundswell with a 16-second period, total energy is a monstrous 5060. And the wind? Dead glassy out of the south in the morning. This is a serious, serious day for experts only. A proper, deep-water groundswell with zero wind. Tuesday the 25th is a solid follow-up, easing slightly to 7ft but still clean.

Wednesday the 26th and Thursday the 27th are a mixed bag, with some wind issues, but Thursday afternoon sees another huge pulse. A glassy 8ft WSW swell with a 17-second period, energy cranking at 3831. Again, the power is for experts. Friday the 28th is onshore and messy.

Looking into the final weekend, Saturday the 29th of August is a solid offer with a clean 8ft swell. Sunday the 30th of August starts off glassy with a clean 7ft WSW groundswell, a tidy way to wrap up the forecast run.

So, your two true standouts? Lock in Friday the 21st of August morning for the cleanest, glassy waves of the first week. And if you've got the skill and the courage, Monday the 24th of August morning is the big-game hunt of the entire forecast.

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.
