The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for Rest Bay over the next couple of weeks.
To be honest, it's a bleak picture for the majority of the forecast. We're looking at a long, dry spell with barely a ripple for the first two weeks. From now until late in the month, it's almost all flat, gutless conditions. There are a few days with light offshore or glassy winds, but with tiny swell, it's just not worth paddling out.
The only real glimmer of hope comes right at the very end of the period. On Monday, August 24th, we finally see a pulse of energy. The morning kicks off with a 4.3ft swell from the WSW, with a period of 7 seconds and a combined energy of (157). That's the most energy we've seen all forecast. The wind is light and offshore from the east, which will keep the surface clean. The afternoon glass off is even better with zero wind, but the swell drops slightly to 3.6ft. It's still just ordinary conditions, but it's the best shot we get. This swell is a bit short-period, so it won't be the most powerful, but it's rideable.
For the rest of the time, you're looking at either flat calm or messy onshore junk. The water temperature is a toasty 68.2°, which is 7.0° warmer than normal for this time of year, so at least you won't be cold waiting for a wave. But honestly, this setup looks more interesting for a kite surfer than a paddle surfer for most of the period.
The 24th is the one to circle. Everything else is a write-off.

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.
