The Lowdown
Alright folks, Rusty here. Let’s be straight with you – if you’re looking to get wet around Rest Bay, you’re gonna be waiting a while. The whole 16-day window looks flat and quiet. We’ve got a long stretch of nothing until the 25th of July, where a bit of energy finally shows up. But even then, it’s a messy situation.
The first real sniff of something is on Saturday the 25th of July. We see a messy 4ft swell rolling in from the west, with a short period of 7 seconds. The wind is cross-onshore, making it choppy, and the combined energy is only moderate at 154. It’s not great. The water is much warmer than usual for this time of year, sitting at 67°, which is about 7° above average – that’s very unusual. Sunday the 26th drops off, with a 2ft to 3ft, short period swell, and the wind is onshore or cross-onshore, so it’s not worth the paddle.
The standout, if you can call it that, is Wednesday the 29th of July. We get a tiny 2ft to 2ft west swell, but the wind goes glassy in the afternoon. It’s clean, but the energy is weak at 19. It’s a small-wave day for a longboard or a foiler, but it’s the only time the wind is truly calm. The rest of the window into August is flat with 0.3ft to 0.7ft swells and clean offshore winds, but it’s just too small to surf.
Honestly, it’s a poor run for Rest Bay. The setup is a beach and point, but with this little swell and strong onshore wind on the 25th, it looks more like a kiteboarding session than a surf. Don’t hold your breath – forecasts can change, but right now, it’s a long blank run.
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.
