Table - best surf conditions forecast for Dumps over the next 16 days.
Alright, Rusty here. Let’s break it down.
The water’s sitting at 59° — that’s about 2° cooler than usual, so it’s a bit fresh, nothing wild.
First real standout is Dumps on Friday July 10. That morning, we’ve got 10ft of SSW swell at 13 seconds, with a combined energy of 2763 — that’s serious power. Wind is cross-off from the SE at 9 mph, keeping it clean. This is a big wave — over 8ft, so experts only.
Saturday July 11 is still real good but smaller. Morning sees 6ft SSW swell, 12-second period, with light offshore ESE wind at 6 mph. Clean conditions, energy at 1161. Strong intermediates can handle this.
Sunday July 12 keeps it going with 6ft S swell, 11 seconds, and glassy offshore SE wind at 3 mph in the morning. Energy drops to 837, but quality is nice. Afternoon goes smaller and cross-off.
Then a lull. Monday July 13 and Tuesday July 14 are flat and weak — 3ft to 3ft, poor conditions. Not worth it.
Wednesday July 15 morning is interesting — only 2ft, but the period jumps to 16 seconds, energy 590. That’s a long-period groundswell, glassy conditions from NW at 3 mph. Points and reefs could see a clean, small wave. Afternoon gets bigger (5ft) but goes onshore.
Thursday July 16 is another highlight. 8ft SW swell at 13 seconds, cross-off SE wind at 3 mph in the morning. Clean, powerful, energy 2143. Expert territory.
Friday July 17 is messy — cross-on wind, chop, not good.
Saturday July 18 — 13ft SSW swell at 13 seconds, energy over 5200. Way too big for Dumps. Clean, but only for the absolute best.
From Sunday July 19, size drops. Monday July 20 morning has a tiny 2ft swell but a very long 19-second period — rare, clean, but barely breaking. Tuesday July 21 picks up to 7ft SSW at 14 seconds, clean cross-off wind, energy 1582.
Wednesday July 22 is another big one: 10ft SW at 15 seconds, energy 3720. Expert only. The rest of the week into July 24 and 25 is huge (11ft to 18ft) with often onshore or cross-on wind. That’s kite-surfing territory, not paddle surfing.
The two true standouts: Friday July 10 morning — big, clean, powerful — and Thursday July 16 morning — also big and clean. Experts only for both. Crowds at Dumps are “sometimes” busy, so not a total madhouse.
Rusty out.

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.
