Right, settle down, grab a coffee, let’s have a look at what’s on the cards for Rest Bay over the next couple of weeks.
Honestly, it’s a tough start. We’ve got a long, flat, and gutless run ahead. From Friday the 3rd of July right through to the morning of Saturday the 18th of July, there’s just nothing worth paddling out for. Day after day of tiny, weak waves with onshore or cross-onshore winds messing them up. The swell energy is mostly pitiful, with readings like 104 (weak) to as low as 5. You’d be better off cleaning the wax off your board than trying to get a ride.
There’s a bit of a tease on the afternoon of Tuesday the 14th of July, with a 2ft, 10-second swell out of the west, combined energy of 86 – still weak – but the wind is light and cross-shore, so it might look tidy, but the wave height is just too small to get any real drive. Don’t get your hopes up.
The first real glimmer of hope arrives on the morning of Saturday the 18th of July. The swell starts to show some life: a 4ft, 7-second west swell, combined energy of 158 – that’s moderate wave energy – and the wind? Glassy. Absolutely glassy. That’s a rare gift. The water here is running at a very unusual 65°, which is much warmer than normal for the time of year, so it’s like a summer bath. The wave period is short, under 8 seconds, so it’ll be a bit lumpy and won't have the real grunt of a groundswell, but for a beach and point break like Rest Bay, with clean glassy conditions, it’ll be the best we’ve seen in a fortnight.
The afternoon of the 18th gets messy again with a cross-onshore wind, so your window is that Saturday morning. Paddle out early. Crowds are likely at Rest Bay, so get there before the masses realise it’s the only game in town. This is the standout – not a classic, but the only real chance for a wave.
So, to sum it up: a long, dead first two weeks, then a brief, clean, and rideable moment on the morning of the 18th of July. Keep an eye on the charts for that one, but don’t book a day off work for the rest.

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.
