Table - best surf conditions forecast for Rest Bay over the next 16 days.
Alright folks, it’s Rusty here, and I’ve gotta be straight with you – this is a tough one to write. Pull up a seat.
We’re looking at a long, long stretch of nothing. The next week and a half is basically a write-off. For the next 16 days, the only true surf recommendation doesn't arrive until Monday, July 27th, which is over two weeks away. Before that, from now right through to the afternoon of the 26th, the surf is just plain poor. There are days where the swell is basically non-existent – we’re talking 0.3ft to 1ft at best, with combined energy readings barely hitting double digits (like 1 to 24). On top of that, the wind is often strong and not in our favour, or it’s cross-on and choppy. There’s a brief moment on the 21st of July with glassy conditions, but with only 0.3ft of swell and an energy reading of 3, it’s not even worth paddling out for. It’s a cruel, flat spell for the first 15 days.
Now, I can see a glimmer of something on the horizon. On Monday, July 27th morning, Rest Bay finally gets a pulse. A 4ft swell from the WSW with a 9-second period will push through, bumping the combined energy up to a moderate 181. The wind is a gentle cross-onshore breeze, which will keep it a little bumpy but rideable. This is the only notable bump in the whole forecast, so it’s all we’ve got. It’s not a clean, perfect day, but after two weeks of flatness, it’s a welcome sight.
The water temp is about average for the time of year, so no need to worry about a wetsuit change just yet.
It’s a lean month, folks. But it tends not to stay this poor for long, and forecasts can change.
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.
