The Lowdown
Alright, let’s break this down. We’re lookin’ at the Dumps, a sandbar that don’t always fire but when it does, it’s worth the wait. Mostly for experienced surfers with the size comin’ through.
Sunday the 19th, you’re lookin’ at chest to head-high waves, around 6 to 7 feet, but the wind’s cross-on, makin’ things choppy. Not the best start. Monday’s similar with lighter wind but still not great. Not worth paddlin’ for the trouble.
Tuesday the 21st, that’s where it gets real. You got a solid 7 to 8 foot southwest groundswell with a long 14-second period. Wind’s south, cross-off, so it’s clean. The energy is strong. This is a session for the confident surfer only. The long period means it might run a bit straight, but there’ll be some good ones.
Wednesday the 22nd, wind shifts onshore again. But hold up for Thursday the 23rd. Thursday morning is clean with 5 to 6 foot waves and light northeast breeze. Then Thursday afternoon? Glassy, clean, 8 foot of southwest swell. That’s the best we got in the first week. No wind, solid size, clean lines.
Friday the 24th, the swell maxes out at 11 to 12 feet in the morning. That’s way too big for this spot and the forecast says it’s too big. The afternoon drops to 10 foot but still massive. Experts only, and even then, it’s sketchy. Saturday the 25th stays big with clean conditions but strong winds, keepin’ it clean but heavy.
From Sunday the 26th through early August, the waves settle into a consistent 4 to 6 foot range, mostly from the southwest, with light offshore or glassy winds. That’s a good run of clean waves, but remember, this spot is inconsistent—so treat each day as a bonus.
A standout there is Thursday the 30th of July: glassy morning, around 4 to 5 foot, clean. And Saturday the 1st of August morning is clean too, 4 to 5 foot with east offshore wind. The afternoon jumps to 16-second period, which is real long—better for points, but the Dumps will have some strong, walled-up sets.
The best of the whole run is Thursday the 23rd afternoon: glassy, 8 feet, southwest swell, clean. Tuesday the 21st is a close second with clean cross-off winds and similar size. Both are for experienced surfers only.

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.
