The Lowdown

Alright, Rusty here. Let's talk about what we've got coming up at Dumps. It's a sandbar set-up, and it can be a bit of a tricky beast – it's inconsistent, so when it fires, you gotta be on it.

The forecast kicks off with some serious, serious energy. For the first couple of days, starting Sunday the 9th, we're looking at a massive 12ft SW swell. The combined energy is pumping at a very strong 3295, but honestly, it's just too much. The wind is a fresh cross-off, but for this break, the swell is predicted to be too big. Unless you're on a gun and looking for a real fight, give it a miss. It stays big through Monday the 10th, with 8ft to 7ft SSW swell and strong cross-off winds, but the call is "marginal" – the tide just isn't playing ball with the conditions.

The real window opens up Tuesday the 11th. The swell drops to a much friendlier 6ft to 5ft from the SSW, and the wind goes light. Tuesday morning, we've got a light easterly offshore at 6 mph, and by the afternoon, it's almost glassy with a slight air. The conditions are expected to be very good. This is the first standout for me – the wave energy is still a solid 896 to 919, which is moderate, but it's the clean, workable size with offshore winds that makes it a winner.

Wednesday the 12th is the second standout. We're looking at a 6ft to 6ft SW groundswell with a very long period of 18 seconds. The energy jumps up to a strong 2217 to 2346, and the wind is a light cross-off from the ENE. This is excellent surf for experienced surfers. That long period means the waves will have real shape and power, but at a beach break like this, that long period can make them a bit bowling and fast. It'll be clean and punchy, but you'll want your wits about you.

We get a bit of a hiccup Thursday the 13th. The swell bumps back up to 8ft, and the wind picks up to a moderate breeze from the NE. The conditions are still clean, but the call is marginal due to the tide, so don't get your hopes up.

From Friday the 14th through the 16th, things get a bit messy. The wind turns cross-on and onshore, with some chop developing. The swell hangs around 6ft to 7ft, but the quality drops right off. It's a bit of a waiting game.

Then we hit another big one. On Monday the 17th, the swell pulses back up to 10ft with a very long period of 16 seconds. The combined energy is a massive 4872. Early morning, the wind is glassy with just a slight air. This is another one for experts only – too big for the average surfer, but for those who can handle it, that glassy, massive groundswell will be a serious session.

The tail end of the forecast, from the 18th to the 24th, is a mixed bag of smaller, cleaner swells and some more big, windy days. The 21st of August looks promising with a glassy morning and a clean 6ft SSW swell. But the 22nd and 23rd bring back the big stuff with cross-on winds, so expect chop.

So, to wrap it up: if you want the best of the best, you're looking at Tuesday the 11th for the clean, fun-sized waves. And for the more experienced crew looking for power, Wednesday the 12th morning is the one to circle. Keep an eye on that inconsistent nature – you'll want to be ready to move when the window opens.

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.
