The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what Rest Bay has lined up for us. Gotta be straight with you – this is a tough outlook. The whole 16-day window is one long, flat stretch. There is no surfable swell on offer for the entire period, from now through to the 17th of August.
Rest Bay (Rest Bay) is a beach and point setup that’s fairly exposed to the west-southwest. But the swell energy coming in is just pathetic. We’re looking at combined energy values that barely tickle 100 (13 on Sunday the 2nd), with most days sitting in the weak zone. The highest we see is 163 on Wednesday the 5th, but even that’s just moderate energy and it’s paired with a stiff onshore wind. The wave comment is consistently “poor surf conditions” – there’s no way around it.
Water temps are running about average for this time of year, but you won’t be worrying about that because you won’t be in the water.
Sunday 2nd August: Tiny 1 ft swell from the west-southwest, period a weak 8 seconds. Cross-off wind keeps it clean, but there’s just no power. Combined energy is only 13.
Monday 3rd: Still tiny, 2 ft in the morning, same direction, period 9 seconds. Energy climbs to 43, but by afternoon the wind swings onshore from the west and chops it up.
Tuesday 4th: Small kick to 2 ft, but the period drops to 8 seconds and the onshore wind picks up to 16 mph. Combined energy reaches 95, but it’s messy. By afternoon, wind hits 16 mph from the west-southwest and it’s all blown out.
Wednesday 5th: The biggest swell we’ll see: 5 ft from the west-southwest, period a short 7 seconds, with a fresh onshore breeze at 19 mph. Combined energy hits 163, but the conditions are poor. This one is for the kites, not your longboard.
Thursday 6th: Swell drops back to 3 ft, period only 6 seconds, and the wind is howling onshore at 22 mph from the west. Choppy and ugly.
Friday 7th through Monday 17th: The rest of the run is a real drag. Swell heights hover between 0.3 ft and 3 ft, periods are short, and wind is almost always onshore or cross-onshore. A couple of glassy moments on Saturday the 8th and Sunday the 9th, but the swell is only 0.3 ft to 1 ft – basically a lake. Combined energy stays in the single digits or low tens for most of that.
There are no standout days here. Don’t bother paddling out for the next two weeks. Leave the board in the shed and check back with me later.
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.
