The Lowdown
Alright, let’s talk surf for the next couple of weeks. Only one break in the mix here: Dumps. It’s an inconsistent sandbar that needs a west swell and can get a few folks out when it’s good. Crowds are sometimes a problem, so keep your head on a swivel.
Saturday morning, 15 August, is the first real green light. Swell is 1.7m from the WSW, 14-second period, and the wind goes glassy out of the ESE at just 5 km/h. That’s about as clean as it gets. Water temp is 55°, which is 5° colder than normal – you’ll want a thick wetsuit. The combined energy is moderate, but the conditions make it a treat. This is the standout early call.
Saturday afternoon stays clean with a cross-off wind and the swell bumps to 2.0m. Good for the experienced guys. Monday 17 August rolls in with glassy conditions again, west wind at 5 km/h, and a 3.0m WSW swell. That’s getting into expert territory, but it’s gonna be pumping.
Tuesday 18 and Wednesday 19 keep that clean cross-off and glassy morning theme, with 1.8m to 2.3m SW swell. Beautiful run.
Thursday 20 and Friday 21 see cross-onshore winds mess up the quality. A bit of a lull.
Then 22 and 23 August – Saturday and Sunday – the swell goes absolutely huge. 4.5m to 5.0m from the SW, period 15–16 seconds, energy levels roaring into four and five figures. But the forecast says it’s too big for this break. That’s survival territory. Skip it unless you’re a masochist.
After that, from Monday 24 August to Wednesday 26 August, the surf settles into a gorgeous pulse. 2.5m to 3.0m SW swell, 13–14 second periods, light offshore or glassy winds. The Wednesday afternoon on 26 August is the pick: 3.0m SW, glassy, 14-second period, energy at 4179. That’s power and perfection. Expert-level, but absolutely firing.
The last few days of August (27 to 29) see stronger winds, but the mornings of the 28th and 29th still offer clean 1.9m to 2.1m SW swells. A nice way to finish.
The two big standout sessions: Saturday 15 August morning for the clean, glassy start, and Wednesday 26 August afternoon for the biggest, cleanest, most powerful swell of the entire run. Monday 17 and Tuesday 25 are also excellent.

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.
