The Lowdown
Alright, this is Rusty. Let’s talk about what’s happening at Dumps.
We’ve got a solid run of surf coming up, but it’s a bit of a mixed bag on the conditions. The early action kicks off on Tuesday the 25th with a solid 8ft swell from the SW, but it’s a bit of a messy one. The wind is blowing cross-off at 12 mph, and that combined energy is pumping at 2459 – there’s plenty of juice, but the report says it’s marginal. Not the best start.
Wednesday the 26th is where things start to clean up. The swell drops a little to 4ft from the WSW, but the wind turns offshore from the ESE in the morning at just 6 mph. That’s clean stuff – the kind of morning where you’re not fighting the wind. The afternoon stays light with a SE breeze at 3 mph, making for another clean session. This is the first standout window: Wednesday morning tops the list for quality early in the forecast.
Thursday the 27th sees a bump in swell to 5ft from the SSW, but the wind turns onshore from the NW. That’s a bit of a shame – the shape is gonna suffer. Friday the 28th is another good one though: morning surf at 3ft from the WSW with a very long 16-second period, and light cross-off winds from the SSE. It’s small but clean, and that long period means the lines will be nice at the sandbar – just don’t expect a lot of size.
The weekend of the 29th and 30th picks up again. Saturday afternoon sees 6ft from the WSW with 14-second period and light cross-off wind – that’s a clean, punchy combo. But Sunday brings stronger S winds at 16 mph, which puts a bit of chop on the face despite the 6ft swell. Still rideable, but not as pretty.
Now, hold onto your board for September 1st through the 3rd. The swell goes huge. Tuesday afternoon the 1st pushes to 10ft from the SW, and Wednesday morning the 2nd is also 10ft from the WSW – but it’s blowing onshore with a light cross-on wind. Then Wednesday afternoon the 2nd hits a beast: 13ft from the WSW, with a combined energy of 9326. That is massive. The conditions say it’s too big for this break – only for absolute experts. Thursday the 3rd is even bigger: 16ft from the SW in the morning with offshore winds. It’s a monster. If you’re not a seasoned charger, sit this one out. This is the standout for serious power, but it’s not for everyone.
After that spike, things ease off. Friday the 4th brings 6ft from the WSW with glassy conditions in the morning – that is a gem. Saturday the 5th has a tiny 2ft swell with a 22-second period from the SW – super long, but small. Good for a log if you’re patient. Sunday the 6th is another clean highlight: 6ft from the WSW with a 15-second period and light offshore SE wind. That’s a tasty morning.
The second week gets more inconsistent. The surf is smaller and the wind picks up again around the 8th and 9th, with fresh breeze and messy conditions. Not much to get excited about there. The water temp is sitting at 56°F here, which is 4° colder than usual for this time of year – that’s notably cool, so a thick suit is a must.
The best bet overall? Wednesday morning the 26th for clean, shoulder-high fun, and Sunday morning the 6th for another clean session with good period. If you’re after size, Thursday the 3rd is the one – but only if you’ve got the skills and the nerve. Crowds are possible at Dumps sometimes, so keep an eye out.
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.
