The Lowdown

Alright, Rusty here. Let's have a look at what's on the menu for the break known as Dumps.

First up, the water is a very unusual 55°F, which is 5°F colder than what you'd normally expect at this time of year. That's a big anomaly, so if you're paddling out, you'll definitely feel that bite.

There's a solid run of surf on offer here, kicking off on Wednesday the 12th of August. The morning will be sweet with a clean 6ft swell from the southwest, pushed by a light cross-off breeze. That’s a proper groundswell with a very long 18-second period, carrying a heap of energy (2329). The wave shape should be excellent for experienced surfers, but the power and size will be too much for beginners. The afternoon holds similar size at 6ft and stays clean with an offshore wind.

Now, Thursday the 13th sees the swell bumping up to 8ft from the southwest in the morning, but the wind goes cross-shore, putting a few ripples on the face. It's borderline for quality. The afternoon turns onshore, so not the pick.

Friday the 14th drops a little in size with a cross-onshore breeze, making for choppy conditions. Not the day to get excited.

Looking for the standout of this run? Aim for Saturday the 15th of August. The morning drops to a glassy, calm wind, with a clean 6ft swell from the west-southwest. The period is a solid 13 seconds, and the energy is moderate (1157). That combination of no wind and a decent-sized, clean swell will make for some really fun waves. The afternoon also looks great, with a clean 6ft and cross-off winds.

Sunday the 16th gets messy with onshore wind in the afternoon, but Monday the 17th comes right back around. Both morning and afternoon on the 17th offer clean, cross-off winds with a solid 8ft swell from the west-southwest in the morning (energy is strong at 2310), dropping to 7ft in the afternoon. That's expert territory, but it will be firing and clean.

The surf settles down through the middle of the week (Tuesday the 18th to Thursday the 20th), with smaller waves and some glassy windows, but it gets a bit smaller. Friday the 21st is small and clean but weak.

The next real highlight pops up on Saturday the 22nd of August, with a clean 5ft swell from the southwest. The following days, Sunday the 23rd and into the final week, show a mix of clean offshore winds and fun-sized swell in the 5ft to 7ft range, especially on Tuesday the 25th with a very long 19-second period swell pushing through.

For a final tip, keep an eye on Thursday the 27th of August. The morning looks epic with a glassy, no-wind condition and a 7ft swell from the west-southwest. That’s a great way to end the forecast window.

Overall, there’s plenty to work with here, with the 15th and the 27th of August being the standouts for clean, quality surf. The biggest issue for the first half of the run is that the water is unusually cold, so suit up.

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.
