The Lowdown
Alright folks, Rusty here. We’ve only got one spot on the radar for the next couple of weeks, so let’s get into it.
We’re looking at a solid run of surf at Dumps, kicking off on Wednesday, July 29th. The waiting game is over. A solid SW groundswell is pumping in with a period of 13 seconds, pushing a combined energy of 1053 (moderate) – that’s some real grunt. Wednesday morning you’ll find 6ft faces with a light E cross-off breeze, making for clean, workable waves. The afternoon sees the breeze swing S, still cross-off, and the energy bumps up a bit (1099). It’s a good start.
Thursday, July 30th, is looking like the pick of the early run. We’ve got glassy conditions in the morning – that’s a dead-calm SE wind – with 5ft SW swell. The energy is still solid at 809. It’ll be clean, tidy, and the sets will have some push. The afternoon drops a little to 5ft but stays clean with a light S cross-off.
Friday the 31st and Saturday, August 1st, ease off slightly. Expect 4ft to 4ft on Friday with clean ESE offshore winds, and Saturday goes glassy again with a touch more period (14 seconds) on the 4ft swell. Both days are fun, lower-energy options.
Sunday, August 2nd, is a write-off. The wind goes cross-on and onshore, and the surf gets messy. Take a day off.
Monday, August 3rd, brings a new pulse. We’ve got a 5ft WSW groundswell with a 14-second period and glassy NE winds in the morning. The energy is nearly back up to 982 (moderate). The morning session is the one to get – the afternoon goes cross-shore and a bit suspect.
Tuesday, August 4th, sees another 6ft WSW swell (11 seconds) with a clean SSE cross-off breeze in the morning – a solid, surfable day.
Now, here’s where it gets interesting for the big boys. Wednesday, August 5th, the swell jumps to 12ft (WSW), with a combined energy of 3935 (strong). That’s serious. But the wind is a cross-on NNW, and the break is a sandbar. This is strictly for experts only. The same goes for Thursday the 6th (10ft, howling 30 km/h N wind, 5935 energy) and Friday the 7th (13ft, 6152 energy). The energy numbers are massive, but the wind and size make it a battle. This setup looks more fun for kite surfers than paddle surfers.
We get a bit of a lull heading into the second week. Saturday, August 8th, stays blown out. The real standout in the long-range is Sunday, August 9th. It’s forecast to be glassy in the morning with a 8ft SSW swell, 12-second period, and a combined energy of 2812 (strong). That’s a lot of power, but the wind is dead calm. This is top-tier for experienced surfers only. The afternoon stays clean with a light S cross-off.
Monday, August 10th and Tuesday, August 11th, are messy with cross-on winds and onshore breezes, though the swell remains in the 8ft-8ft range. The quality won’t be there.
The run finishes off with a clean-up. Wednesday, August 12th, is glassy again with a 4ft WSW swell (12 seconds) – a nice, easy day. And then Thursday, August 13th, looks like a final big-swell payday. We’re looking at a 10ft SW swell with glassy NNW winds. The energy is 3731 (strong). That’s an excellent, powerful, clean day for the experienced crew.
Overall, the best of the best is the glassy morning of July 30th (5ft, SW, clean) for the average surfer, and the glassy morning of August 9th (8ft, SSW, powerful) for the experts. The long-range stuff on August 13th is promising but a week and a half out, so keep an eye on it.
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.
