The Lowdown
Right, let's have a look at what's on offer. To be straight with you, it’s a pretty grim stretch ahead for Rest Bay. I’ve scanned the whole 16-day window, and there’s not a single standout session that gets me excited. The first week is a write-off, with barely a ripple and mostly onshore or cross-off winds messing with what little there is. We’re looking at a solid gap of over a week with nothing worthwhile before we see any real potential.
The only time the swell shows any serious life is right at the end. On Thursday morning, the 3rd of September, a big chunk of energy rolls in – combined energy hits 1173, which is strong to very strong. The swell is 7ft from the WSW at 11 seconds, which is a proper groundswell. That size and period will make for powerful, lined-up waves, but it’s big enough that it’s really only for experienced surfers. The morning is clean with a cross-off wind from the SE, which is a big plus for Rest Bay, but that onshore wind forecast for the afternoon will chop it up. It’s a promising blip, but with the wind shifting, you’d need to be out there early.
The water temperature is about average for this time of year.
Because there’s nothing else that comes close, that Thursday morning on the 3rd is the best on offer, but don’t get your hopes up too high; it’s still a long way out and forecasts can shift.

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.
