The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming up for Dumps.
Right off the bat, we've got a bit of a wait for the good stuff. This first week is a tease. Tuesday the 21st is a non-starter with an 8ft SW swell but cross-shore winds making it a mess. The next few days are pretty average, with only marginal conditions and onshore or cross-shore winds messing things up. The energy is moderate but the quality isn't there.
The real standout is Friday morning, the 24th of July. We're looking at a solid 12ft groundswell from the SW with a very long 14-second period, and the wind is forecast to be glassy. That's a recipe for perfection. The combined energy is strong (4749), but the catch is this is likely too big for most punters. This is for the experienced crew only. The following Saturday, the 25th, keeps the quality high with a 7ft to 8ft SW swell and clean offshore winds in the morning, offering excellent conditions for those who know what they're doing. The water is sitting at 58°, which is a bit colder than normal for this time of year.
Then we get another pulse. Tuesday the 28th of July morning has a 10ft SW groundswell with a very long 16-second period and light offshore winds. Again, this is big, powerful, and clean. The energy is strong (4414). This is the other peak to circle.
The swell backs off towards the end of the month, but Thursday the 30th of July morning offers a glassy 6ft swell with no wind at all. It's a nice, mellow window for the less experienced.
Looking into the first week of August, there's a big blank run. The surf drops right off, with poor conditions and tiny swell from the 2nd through the 3rd. Then on the 4th of August, things start to pick up again, with a clean 5ft to 6ft SW groundswell showing promise. But the next big one, on Wednesday the 5th of August, is another 12ft beast from the WSW, which is probably too big and onshore. It's a pattern of feast or famine.
Remember, Dumps is an inconsistent sandbar, so when it fires, it's a treat, but you have to be ready for the big stuff. The few standouts are the 24th and 28th of July mornings for the experts, and the 30th of July for a glassy, smaller session.
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.
