The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on offer for the next couple of weeks.
Truth be told, it’s a pretty grim outlook for the entire 16-day window. We’re looking at a long stretch of poor surf conditions, with only a glimmer of something rideable right at the end. The first real chance of a wave that’s even worth a paddle comes on the morning of Thursday, August 13th at Rest Bay (beach and point). Even then, it’s just 0.5 ft of swell from the WSW with a period of 9 seconds, and the combined energy is a weak 67. The winds are light and cross-offshore though, which will keep it clean. But it’s hardly a standout.
The real story is the gap. After that Thursday, it’s back to poor or flat conditions for the rest of the month. The wind stays onshore or cross-on, and the swell is either tiny or messy. You’re looking at a solid week of nothing. A couple of afternoons around the 21st and 22nd of August will see the swell bump up to 4 ft from the WSW, but the wind is onshore and the period is a short 6 seconds, so you’re just getting lumpy, weak lines. The combined energy climbs to 104 and 130, which is firmly in the moderate range, but without the right wind, it’s a kite setup, not a surf one.
The one morning that might get your hopes up is the 23rd of August. The wind is light and cross-shore, which is promising, but again the swell is small and the period is short. It’s a tease.
Honestly, friends, this is a blank run. The break is fairly consistent, but the conditions are just not cooperating. It’s one of those stretches where you’d be better off checking the forecast again in a few days. I’ve got nothing to get excited about here.
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.
