The Lowdown
Right then, let’s have a look at what we’ve got for Rest Bay over the next couple of weeks. I’ll be straight with you – it’s a tough run for most of it. The water temp here is sitting at 67°, which is a solid 6° warmer than what’s normal for this time of year, so that’s very unusual for September.
The pattern starts with nothing worth paddling out for through Wednesday the 9th and all of Thursday. The wind is onshore or cross-onshore, and the swell is weak and messy. Friday the 11th morning has a bit more energy, combined swell energy up to (177), and a 3ft swell from the WSW, but that cross-on wind from the WNW kills it. Not clean enough to get excited about.
Saturday the 12th afternoon sees the swell bump up to 5ft from the WSW, but it’s getting thumped by a 22 mph onshore wind, which makes it rough. That’s more of a kite-surfing setup than a paddle session. The energy is moderate at (192), but the quality is poor.
Sunday the 13th morning offers a glimmer – a 3ft WSW swell with a longer 10-second period, and only a light breeze. The combined energy is solid at (255), and it’s cleanish, but the cross-on wind still keeps it from being a standout. Monday and Tuesday are tiny, with swell dropping to 2ft, so not worth the drive.
Now, here’s the one that catches my eye. Wednesday the 16th morning brings a jump to 7ft from the WSW with a 9-second period, and the combined energy hits a strong (645). The wind is cross-off from the NNE at 16 mph, so it’ll be clean. That’s a decent push of groundswell, but at over 7ft, it’s getting into expert territory – too big for beginners. The 9-second period means the sets won’t be too drawn out, which helps at a spot like Rest Bay (beach and point). It’s the biggest, cleanest wave in the whole outlook, and I’d say that’s the standout. Just be aware it can get busy – crowds are often here.
After that, Thursday the 17th drops off again, and from Friday the 18th onwards it’s back to tiny, weak surf with energy readings below 100. There’s nothing else worth mentioning until Thursday the 24th afternoon, when a glassy 2ft W swell creeps in with clean conditions. At least it’s surfable, but very ordinary. That’s over a week of flatness in the middle – a long dry spell for the area.
So, to wrap it up: if you’re a confident surfer, mark Wednesday the 16th morning on your calendar. That’s your best shot. Otherwise, it’s a waiting game. Forecasts can change, but right now, it’s a quiet run.

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.
