The Lowdown
Alright, let me break this down in feet and miles per hour for you.
So, taking a gander at Dumps, the next couple weeks are looking really solid for the crew who chase proper groundswell. There’s a consistent run of good-sized, powerful WSW to SW swells coming in.
The first real standout is Saturday morning, August 15th. It kicks off with nearly glassy conditions, a clean 6ft swell from the WSW with a 14-second period. The wave energy is reading 1120 (moderate). Water temp is about average for this time of year. This is a perfect window for an intermediate surfer to get a real eyeful without it being a zoo.
It builds to 7ft Saturday afternoon (SW, 13s) with light offshore wind, staying clean, but the absolute pick of the first week is Monday morning, August 17th. You’ve got 10ft of swell from the WSW (13s), glassy conditions, and the energy is pumping at 2586 (strong). That is a powerful, big-wave day. Only for the experienced crew.
We hit a real ugly patch on Saturday, August 22nd. A strong westerly wind of 25 mph kicks up, blowing cross-onshore with rain and a massive 12ft swell. That is a total mess for a surfer. That setup is a kite-surfer’s dream and a paddle-surfer’s nightmare.
It cleans right back up from Sunday, August 23rd. The next major highlight is Tuesday morning, August 25th. You get a 8ft swell from the SW with a very long 17-second period. The energy is 3496 (very strong), and with light offshore winds, it will be exceptionally clean and powerful. That long period will make the sets stand up tall and grind perfectly, with longer lulls in between.
The last few days of the month finish strong, with a cleaner 7ft on Saturday, August 29th (SW, 12s, offshore wind) offering some more user-friendly but still meaty conditions.
Just a heads-up: Dumps can get crowded when it’s like this. And since it’s an *inconsistent* spot, a run this good is something you drop everything for.

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.
