The Lowdown

G’day, Rusty here. Look, I’m gonna be straight with you—this stretch for Rest Bay is a tough one to call a surf outlook. We’re looking at a flat spell that’s going to test your patience. From the start of the forecast right through to the middle of next week, it’s pretty much a write-off. There’s some small, weak energy but nothing rideable. The water’s sitting at a balmy 69°, which is a full 8° warmer than usual for this time of year—that’s properly weird, almost like bathwater.

For the first week, from Wednesday the 5th of August right through to Sunday the 17th, it’s all poor surf. We’ve got a mix of onshore and cross-onshore winds from the west and WNW, blowing 19 to 22 mph, making everything lumpy and choppy. Swell heights barely touch 3 ft and periods are short—mostly around 6 to 7 seconds. The combined energy is weak, staying in the double digits for most of it, nothing worth paddling for.

There is a blip on Monday the 17th of August, but it’s a messy one. A big pulse of WSW swell hits 10 ft with an 11-second period, and the combined energy rips up to 2049—that’s a lot of juice. But the wind is cross-on from the WNW at 16 mph, so expect lumpy, blown-out conditions. That size is too big for beginners, and with the wind on it, even experienced crew will be wrestling it. Honestly, it looks more like a day for kites than paddles.

After that, it drops fast. The rest of the second week is back to tiny, weak swell and more wind. There’s no stand-out session here. If you’re desperate, the cleanest windows come on the morning of Tuesday the 11th with light SE cross-off winds, or Wednesday the 12th with easterlies, but you’re looking at ankle-to-knee-high waves. It’s just not happening.

Take it easy, wait for the charts to change. This is a blank run that’s normal for the area when the wind gods aren’t playing ball.

Rusty.

Information about the Rest Bay Surf forecast

The above surf forecast table for Rest Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rest Bay can be found by selecting the local surf guide option on the grey menu. Our Rest Bay 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 (Rest Bay) 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 Rest Bay 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.
