The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of swell on the way, but it kicks off with some serious size that’s not for everyone. The window opens this Friday morning, July 24, and it’s a big one.

We’re looking at Dumps first up. This sandbar setup is inconsistent, so when it’s on, you gotta be on it. We start Friday morning, July 24, with a clean, glassy morning and a massive 12ft SW groundswell. The combined energy is pumping hard at 4757 (strong to very strong wave energy). That’s a lot of water moving. The period is a long 14 seconds, which is a proper groundswell, and at over 8ft, this is strictly for experienced surfers only. That SW direction is right on the money for the optimum here. The wind is dead calm, glassy conditions – absolute magic if you’ve got the skills. It’s likely to be a bit of a circus with the crowds, so expect a lineup.

The swell drops back a touch through Friday afternoon, still 10ft and clean with a cross-off breeze, but the same caveat applies: this is big, powerful stuff for the crew who know what they’re doing.

Saturday morning, July 25, sees a 7ft, 13-second swell. Still a solid groundswell, and the combined energy is 2016 (strong). It’s clean. By Saturday afternoon, it’s 8ft and still clean. The standouts here are really those first two days of the forecast – the glassy, big, clean windows on Friday morning and Sunday morning, July 26, when the wind goes glassy again on a 7ft, 12-second swell.

By Monday, July 27, the wind kicks up. We’re talking 22-25 mph cross-off winds. The swell is still big, but the conditions are marginal. The water temp is about average for this time of year, nothing unusual there.

The next real standout comes after that blow. Tuesday morning, July 28, the wind swings offshore and stays moderate. The wave energy is 3614 (strong) on a 10ft, 15-second swell. That’s a very long period groundswell, which will be lining up on Dumps, but at a beach break, a period that long can make things a bit straight. Still, for the experienced surfer, that’s a session to circle.

The pattern continues with good, clean surf through the end of July and into early August. August 1, Saturday, has a nice 5ft, 13-second swell and clean conditions in the morning. There’s a gap after that Sunday, August 2, where the wind is onshore and the quality drops out. That’s a day to skip.

But then it picks up again. Tuesday, August 4, brings a clean 5ft, 14-second morning with offshore wind, and the size builds back up. Wednesday, August 5, is a genuine standout: glassy conditions, 8ft, 13-second SW groundswell, and the energy is 1817 (strong). That morning is as good as it gets here for a clean, big swell.

The last few days of the forecast run into some cross-onshore wind and marginal conditions from August 6 onward, but Dumps is a rare bird. When it’s on, it’s a proper wave. The best of the best is that first Friday glassy morning, and then the Tuesday-to-Wednesday window early in August. Keep an eye on the wind, and don’t sleep on that glass.

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.
