The Lowdown
Alright, Rusty here. Let’s break it down. Dumps is gonna take a few days to get going, but when it does, there’s some serious juice.
Tuesday the 14th is a total flat start. Only 3ft swell from the west at a short 10 second interval, cross-on wind, weak energy (222). Water temp is 57°, a bit chillier than normal. No reason to paddle.
Wednesday the 15th morning flips the script. Swell builds to 5ft from the SW with a very long 17 second period – that’s real groundswell. Glassy conditions, energy jumps to 1330. This is the cleanest window, but the break is inconsistent, so you’ll be waiting. That long period will make the sandbar a bit straight. Afternoon gets cross-shore and surges to 8ft – expert-only territory.
Thursday the 16th morning is glassy with 8ft SW swell at 13 seconds (2381 energy). Only for the experienced. Afternoon stays big with cross-shore wind.
Friday the 17th through Monday the 20th: a nice run of clean to glassy mornings with 5ft to 6ft SW swell. Light winds, mostly offshore. Consistent fun for a good surfer.
Tuesday the 21st gets nasty – 10ft SW swell with 15 second period, but cross-wind at 15 mph. Afternoon has 13ft swell and onshore wind – that’s kite territory. Wednesday the 22nd is a complete mess with 25-28 mph winds.
Thursday the 23rd afternoon and all of Friday the 24th are excellent for experts. Swell drops to 7-8ft from the WSW, clean, light offshore wind. Top quality.
Saturday the 25th is the big winner. Morning has 4ft from the SW at a monster 19 second period, glassy. Perfect for a clean longboard session. Afternoon jumps to 8ft at 16 seconds, still glassy. An absolute standout.
Sunday the 26th stays solid but the wind picks up. Monday the 27th morning offers clean 5ft WSW swell with offshore breeze – a great way to finish. Tuesday and Wednesday the 28th-29th get blown out by strong winds and big lumpy swell.
Best calls: Wednesday morning the 15th for the glassy, long-period magic, and Saturday the 25th for back-to-back glassy perfection. Inconsistent spot, but when it’s on, it’s on.

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.
