Table - best surf conditions forecast for Rest Bay over the next 16 days.
Alright, let me have a look at what we’ve got for the next couple of weeks here at Rest Bay.
Honestly, mate, I’m struggling to find a proper session in this whole 16-day window. The swell is tiny, barely a ripple most of the time, and the wind isn’t doing us any real favours. It’s a tough stretch for a paddle.
We start off on Wednesday, July 8th, with a weak 1 ft swell out of the WSW at 8 seconds, and a cross-on wind makes it messy. That sets the tone. Thursday isn’t any better, same tiny waves, cross-on again in the afternoon. The combined energy is barely a whisper, with readings like 14 and 19, just flat and weak.
Friday the 10th has a clean little cross-off wind, but the swell is still only 1 ft from the WSW, period 9 seconds. It’s clean, but you’d be scratching for a wave. The combined energy is only 29, which is very weak.
Saturday and Sunday are the same story – tiny, clean conditions but with hardly any swell. Sunday morning there’s a 22 mph offshore wind, but it’s blowing over a 0.3 ft wave. It’s clean, but there’s nothing to ride.
The water temperature is a standout oddity here – at 66°F, that’s a massive 7°F warmer than normal for this time of year. Very unusual, but it doesn’t help the wave count.
The whole first week is a write-off, nothing above 2 ft, and most days the combined energy is in the single digits or low teens. There’s a little bump on July 19th with a 2 ft swell from the NW, but the period is a pathetic 3 seconds – that’s windswash, not surf. And the wind’s onshore.
Towards the end of the run, like July 21st, we see a 2 ft swell from the WNW, but again, period of 4 seconds and strong onshore winds. The wave energy is still tiny, only 13. It’s not surfable in any meaningful way.
To be blunt, there isn’t a single standout session in this entire outlook. The best you can hope for is a clean, glassy morning on July 16th, but with a 0.3 ft, 14-second swell, it’s more of a flat spell than a surf. The long period suggests a groundswell, but there’s no height behind it.
It’s a blank run, plain and simple. For a beach and point setup like Rest Bay, this kind of flat spell is normal for the area in these conditions. Keep an eye on the forecasts, because it can’t stay this poor forever.

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.

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.
