Table - best surf conditions forecast for Dumps over the next 16 days.
Alright, Rusty here, let’s look at what’s cooking for Dumps.
Alright, we’ve got a bit of a mixed bag ahead. The coming week starts off pretty ordinary, but there’s some serious juice on the way if you’ve got the patience. The water’s sitting at 57°, which is a bit colder than normal for this time of year, so don’t forget a good hood.
Monday, the 13th, is a slow starter. We’ve got waist-high waves around 3ft, but the wind is glassy, so it’s clean. It’s just very weak energy (257), so you’ll be hunting for scraps. Tuesday the 14th is pretty much a write-off with onshore wind and poor conditions.
Now, Wednesday the 15th is where things get interesting. The swell jumps to 5ft from the SW with a very long period of 17 seconds. That’s a proper groundswell, and with glassy conditions in the morning, it’s going to be excellent for experienced surfers. The energy is moderate (1495), but that long period means it’ll be better shaped and have more push. Just keep in mind, at a sandbar like Dumps, a long period SW swell can sometimes break a bit too straight, so pick your peaks.
Thursday the 16th keeps the energy going with 8ft swell from the SW and glassy conditions again in the morning. This is clean, powerful stuff, but it’s getting into expert territory. The energy is strong (2241) and the period is a solid 13 seconds. Friday the 17th backs off a touch to 7ft, but the wind is cross-offshore and clean, making for some very good sessions.
The weekend sees a drop in size on Saturday the 18th, with messy onshore winds, so not the best. But Sunday the 19th comes back with a clean 7ft SW swell (12 seconds) and cross-offshore wind, delivering some very good waves.
Here’s the true standout: Tuesday the 21st. We’re looking at a solid 10ft swell from the SSW with a 16-second period and glassy conditions in the morning. The energy is massive (4415), and this is big, powerful, and clean. This is only for experts, but if you’ve got the skills, it’s the best session on offer.
The end of the month gets wild again. Saturday the 25th has a 7ft SW swell (15 seconds) with clean cross-offshore wind, and Sunday the 26th kicks off with a glassy 10ft from the WSW. That Sunday morning looks excellent for experienced surfers, but by the afternoon, the swell spikes to 12ft, which is just too big for this break.
On the 22nd, a strong NW wind kicks in and ruins the surface, so that’s a skip. The 23rd and 24th also have issues with size or wind. Overall, the best windows are Wednesday the 15th morning, Thursday the 16th morning, and absolutely Tuesday the 21st morning for the biggest, cleanest swell.
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.
