The Lowdown

Alright, Rusty here, let’s take a look at what’s comin’ our way.

First up, we’ve got Dumps. This spot is a bit of a fickle beast—only breaks on the right swell, and even then it’s inconsistent, so when it lines up you gotta make the call. The season is kickin’ off with some decent energy.

Starting Thursday the 30th of July, we’ve got a clean 5 ft SW swell with a solid 13-second period pushin’ in. That’s proper groundswell, and with the ESE wind blowin’ light offshore at 3 mph, Dumps is lookin’ glassy. The wave energy is moderate at 809, but it’s still gonna be a fun session. The water temp is about what you’d expect for this time of year, nothin’ freaky.

Friday the 31st sees the swell droppin’ a bit to 4 ft, still that SW direction, period hangs around 12 seconds. ESE offshore again in the morning at 3 mph keeps it clean. Not huge, but a mornin’ paddle will be worth it. Afternoon gets a little messy with cross-shore wind.

Saturday the 1st of August is a real treat—clear skies, glassy conditions with the ESE wind goin’ flat calm. That 4 ft SW swell bumps up to a 14-second period, makin’ for some real nice, lined-up waves. Energy is moderate (581), but the quality is there. This mornin’ session is one of the better ones in the near term.

Sunday the 2nd keeps the good vibes rollin’. Wind goes glassy from the NNW in the mornin’, then swaps to WSW glass in the afternoon. Swell holds at 4 ft to 5 ft, SW direction, period 12-13 seconds. Clean all day, not crowded, just you and the ocean.

Monday the 3rd of August is a standout. The wind is totally calm, dead glass. That 5 ft SW swell has a 12-second period and the energy jumps to 995—still moderate but gettin’ punchy. This is the best mornin’ of the first week. Smooth, clean, and the sandbar will be workin’. Afternoon stays clean with a light cross-off breeze.

Tuesday the 4th is still fun, mornin’ glassy with 5 ft SW swell, but the energy is dialin’ back a bit. Afternoon gets a little weird with onshore wind.

Now, hold onto your board. Wednesday the 5th of August, a big pulse arrives. That’s a 10 ft to 12 ft SW swell with a 14-15 second period, but the wind is rippin’ cross-onshore at 12-15 mph, makin’ it choppy and messy. Wave energy is huge (over 4000). This is not a paddle day unless you’re after a beatin’. The waves are gonna be too big and blown out for most.

Thursday the 6th of August is where it gets serious for the experienced crew. Swell hits 13 ft from the WSW with a 14-second period, energy is a massive 6275. The wind is cross-off at 9 mph, so the faces will be clean, but the size is only for experts. The tide conditions might make it sketchy for this break—could be too big for Dumps to hold properly. If you’re not confident, sit this one out.

Friday the 7th, still huge but onshore wind messes it up. Not worth it.

Then we hit a quieter spell. Saturday the 8th through Monday the 10th has rain showers and onshore winds, with swell still a bit jumbled. Not your best window.

The real gem of this whole forecast is Monday the 3rd of August. That dead-calm glass, with 5 ft SW groundswell, wind off, and clean conditions—that’s as good as it gets at Dumps in this outlook. The other standout is the mornin’ of Saturday the 1st of August with that 14-second period and glassy skies. After that, the big stuff in the second week is for the hardcore only.

If you’re new to the water, any swell over 5 ft might be a handful, and once it’s over 8 ft, it’s expert territory. From the 5th onward, it’s all big and powerful, so choose wisely.

Stay stoked,
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.
