The Lowdown

Right, let’s have a look at what’s lined up for Dumps. This is a sandbar that’s inconsistent but when it turns on, it’s got some serious punch. The water’s about average for this time of year, nothing unusual there.

The forecast has a bit of a slow start, nothing worth getting out of bed for on Thursday, even with that 7ft SW groundswell (1231 combined energy). The wind is messy and the surf is just poor. It’s not really a goer.

But Friday morning, July 24th, is the standout. Get this: glassy conditions, zero wind, and a solid 12ft SW groundswell with a 14-second period, pushing a massive 4555 combined energy. The swell is big, over 8ft, so this is strictly for experts. For the experienced crew, this is going to be a session to remember at Dumps, with that clean, folding power. The swell direction (SW) is a good match for the break’s optimum. It’s inconsistent here, so expect long lulls between sets, but those waves will be worth the wait. Crowds are sometimes a thing here, so on a day like this, expect a few others in the know.

Saturday morning, July 25th, is still clean and strong – 7ft SW, 13-second period, with light offshore wind (SE 3 mph). Combined energy is a solid 1865. It’s excellent for experienced surfers, but it’s a step down from Friday’s peak.

Sunday, July 26th, starts glassy with a clean 6ft SW swell, but the overall energy (1209) is dropping. Still a very good morning surf.

The start of the next week, from Monday July 27th, gets interesting again, but it’s pushing into big, windy territory. Monday afternoon sees a 13ft S swell (5293 energy) but it’s too big for this break and the wind is howling. Tuesday July 28th has a massive 12ft SW groundswell with an 18-second period, and strong offshore wind (25 mph). That’s a staggering 7884 combined energy, but the wind is so strong it’ll be hard to paddle into, and the swell is huge. Experts only, and a battle.

The end of July and start of August sees the swell back down to a more manageable 4ft to 6ft range, with plenty of glassy mornings and light winds. It’s consistent, clean, and fun for intermediates, but not a standout compared to that Friday the 24th.

Then, looking way out, on Wednesday August 5th, another solid pulse arrives: 8ft SW groundswell, 16-second period, with light offshore wind (E 6 mph) and a combined energy of 3154. That’s a long-range call, so treat it with a bit of caution, but it looks promising for experienced surfers again.

The best on offer is crystal clear: Friday morning, July 24th, at Dumps. That glassy, 12ft, 14-second SW groundswell is the one. Get it while it’s hot.

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.
