The Lowdown
Right, let’s have a look at what’s cookin’ at Dumps. The water’s running about 57°F, which is a few degrees cooler than usual for this time of year, so you’ll want a thicker suit. The first real action kicks off Monday morning the 24th with a clean 6ft groundswell from the WSW, with moderate energy in the water (794). The wind’s a light cross-offshore, so it’ll be glassy. That’s the one to aim for early.
Tuesday morning the 25th brings a bigger 8ft SW swell, but it’s a bit bumpy with a moderate cross-off breeze. The energy jumps up (2459), but it’s not as clean. Wednesday the 26th is a gem: a light offshore wind, a clean 5ft WSW swell, and moderate energy (856). It’s an inconsistent sandbar, but when it’s on, it’ll be smooth. That Wednesday morning is your best bet.
Thursday the 27th and Friday the 28th the swell drops. Friday has a super long-period 16-second groundswell at 3ft, but the energy is still moderate (675) and it’s dead clean with a light offshore. That long period might make it tricky on the sandbar, but it’ll be glassy. Saturday the 29th is a write-off with cross-onshore winds.
Sunday the 30th gets big – 10ft to 12ft WSW swell, with energy through the roof (6261). That’s expert-only stuff, and the wind is a fresh cross-offshore, so it’s clean but heavy. Might be more for the kite surfers. Monday the 31st is the best of the big stuff: 8ft WSW swell, light winds, clean, and strong energy (1806). That’s for experienced surfers only.
The first week of September is a mess – strong winds, rain, and massive swell up to 21ft on Wednesday the 2nd (29880 energy). Way too big. It’s not until Monday the 7th that things clean up with a fresh offshore wind and a 6ft WSW swell (1176) – that’s a solid session for the confident surfer.
The big standout is Wednesday morning the 26th for clean, fun waves. Monday the 31st is the heavy hitter for the experts. After that, wait until the 7th of September for the next clean window.

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.
