Alright, gang, Rusty here. Let’s get into what’s cookin’ at the sandbar.
There’s a bit of a dry spell before the real action starts, so don’t rush out the door just yet.
Saturday, July 11th is where we begin. We’ve got a clean 7ft swell out of the SSW, with a long 12-second period. The combined energy is pumping (1248), and a light offshore breeze is making those faces glassy. This spot is inconsistent, so when it does this, it’s a treat. Water temp is 59°F, which is about normal for this time of year.
Sunday morning, July 12th is the early pick: 6ft from the south, 11-second period, still with clean offshore wind. The energy is solid (830).
Then it’s a lull. Monday and Tuesday drop to under 3ft with junky wind. Not worth the effort.
Wednesday afternoon, July 15th we see a spike. An 8ft SSW swell with a very long 15-second period. The energy jumps to 2815. There’s a cross-shore wind, so it’s not perfect, but the size and power are undeniable. For an inconsistent sandbar, that long period swell could offer some great waves, though it might run a bit straight.
Thursday, July 16th morning is the real standout. A big 10ft SSW swell with a 13-second period, energy at 3003, and a cross-offshore wind. That’s big, powerful, and clean. Expert territory only. That wave is a beast. The afternoon holds at 8ft with good wind, too.
Friday, July 17th is the gnarliest day on paper. Swell hits 12ft from the SSW, with energy readings of 3432 and 3786, all with clean offshore wind. At that size, Dumps is going to be an absolute monster. It might be too much for the break itself, but for the elite crew, it’s a spectacle.
After that, Saturday, July 18th drops to a much more user-friendly 6ft with clean offshore wind. Good day! Then the wind turns foul from Sunday through Tuesday—strong cross-onshore winds and chop kill it.
We get another pulse from Wednesday, July 22nd, with 6ft swell, but the wind is still messy, making it marginal.
The long-range looks mint. Thursday, July 24th morning brings back clean 7ft SW swell and cross-offshore wind. Saturday, July 25th morning is glassy with 7ft SW swell. That’s going to be a perfect day.
Best of the forecast: Wait for the big ones. The clear standout is Thursday, July 16th morning – 10ft SSW, clean, and packing a punch. The second is Saturday, July 25th morning – glassy, 7ft SW, absolute perfection.
Stay frothy.
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.
