The Lowdown
Alright, grab a cuppa, let’s have a look at Rest Bay. This is a tricky one, mate. We’ve got a 16-day window stretched out ahead of us, but the honest truth is that for the first week and a half, it’s going to be a write-off. Honestly, for a long stretch from Monday the 24th of August right through to Thursday the 28th, the swell is tiny – we're talking knee-to-ankle high, and the energy is just pathetic, mostly hanging around the single digits (17 or lower). The wind is doing it no favours either, mostly cross-off or cross, but with no size to work with, it’s just flat and frustrating. You'd be better off doing anything else.
We do start to see a pulse of energy building towards the end of the first week, particularly around Friday the 28th. The morning brings a small 1.0 ft cross-on swell, and by the afternoon, the swell bumps up to 1 ft, but that comes with a full-on onshore howler (16 mph) and a short, choppy period of 6 seconds. The whole setup looks pretty average for paddling, honestly, and with that wind and a beach setup, this is looking more like a kite-surfing session than a paddle-surfing one.
The period from Saturday the 29th through to the 5th of September is a real mixed bag. We get some bursts of energy – on Monday the 31st of August, we see 2 ft from the west with a combined energy of 342, but it’s smothered by strong onshore winds (22 mph), making it lumpy and unrideable for a proper wave. There’s a noticeable spike on Wednesday the 2nd of September, with 2 ft of swell coming onshore, and the following days hold similar size, but the wind is always there to spoil the party. This whole block is just messy.
Now, let’s talk about a true standout, but you’ll have to be patient. The real magic shows up on Monday the 7th of September. The morning starts quiet, with a small 0.7 ft swell, but then the afternoon just fires up. We get a solid 2 ft of swell from the WSW, and the combined energy hits a massive 899, which is seriously powerful. This is a long-period groundswell too, with a period of 14 seconds, meaning it’ll have some serious shape and push, and is best suited for the point or reef sections of Rest Bay. Crucially, the morning of that day also has near-glassy conditions (slight air, 3 mph), which could clean things up nicely. This is the pick of the entire outlook for sure.
For beginners, anything above 2 ft is getting spicy, and that 2 ft with that power is for confident intermediates and above. The crowd situation at Rest Bay is often busy, so expect company on that best day.
The water temp is about average for the time of year, nothing unusual to report.
So, to sum it up: a long, flat, windy gap for the first week. Thursday the 3rd of September has some solid 2 ft swell, but it’s not clean. Your true best day is Monday afternoon the 7th of September with that big, clean, long-period groundswell. It’s a promise, but it’s a good one.

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.
