The Lowdown
Alright folks, Rusty here. Let’s break down what Rest Bay is cooking up for the next couple of weeks. I’ll be honest, it’s a slow one—a long stretch of flat before we get anything worth paddling for.
We kick off with absolutely nothing. From Monday the 27th of July through Friday the 7th of August, it’s a ghost town. The swell is tiny, the wind is mostly onshore or cross-onshore, and the energy is pitiful—starting at 64 and just falling away. The water temperature on that first Monday was a very unusual 69°F, which is about 8°F warmer than normal for this time of year. That’s some seriously warm water, but it’s not doing a thing for the surf. The swell period is a weak, short 6 seconds—just messy wind chop. For a week and a half, don’t even bother.
There’s a tiny glimmer on Friday afternoon the 7th of August. The wind goes dead glassy, and we see a little 3ft swell pop up. The energy bumps to 46, but it’s still a short-period 5-second windswell. It’s glassy, but the quality is still listed as poor. A tease, really.
The one and only standout in this whole 16-day window is Saturday morning, the 8th of August. Get up early, because that’s your moment. We’ve got a solid 5ft swell rolling in from the west with an 8-second period. The combined energy hits a respectable 253, and the wind is glassy—that’s the golden word. Glassy conditions will make Rest Bay look its best, even if the swell is a little on the short side. Being a beach and point break, with that west swell and offshore wind from the north-northeast, it’ll be clean and fun. That 5ft is at the limit for beginners, so if you’re newer, have a look before you jump in. Crowds here can be ‘often,’ so expect some company.
After that Saturday morning, it fades fast. Sunday the 9th and Monday the 10th of August drop back down to under 3ft with clean but weak conditions, then it’s back to tiny, junky surf for the rest of the run.
So, the bottom line: one solid bet, and that’s Saturday the 8th of August. Get out early for the glass and the biggest push of the whole forecast. The rest is a flat spell you can sleep through.
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.
