The Lowdown
Hey, it's Rusty. Let's talk about the next couple of weeks at Dumps. This is a sandbar break, and it's inconsistent – it doesn't fire often, so when it does you've gotta be on it. Water temp is sitting around 58.6°, which is about average for this time of year. The first few days are pretty average, but there are a couple of real windows that'll get your blood pumping.
Sunday 19 July – forget it. Cloudy, cross-on wind, 6.2 ft of weak-ish WSW swell (combined energy 1925) but it's choppy and messy. Monday 20 July – smaller, onshore, not worth a look. Then Tuesday 21 July morning – bingo. Glassy conditions, 7.2 ft of SW swell with a long 14-second period, energy reading 2005 – that's a proper groundswell. The interval is long so at a sandbar it might break a little straight, but the glassy surface will make it clean. Good for intermediate surfers. The crowds are sometimes here,

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.
