The Lowdown
Alright, let’s get straight into it. Look, I’ll be honest with you—this is a tough stretch for Rest Bay. We’ve got a blank run here for the first week and a half. There’s nothing worth paddling out for from Tuesday the 11th all the way through to Sunday the 23rd of August. No recommendations at all. That’s a solid gap of around 12 days with nothing doing. The only tiny whisper of surf comes in around 0.3 ft to 2 ft, weak energy, and the wind is mostly onshore or cross-onshore, often fresh and lumpy. It’s a grim run, and the water temperature is about 68°F, which is much warmer than normal for this time of year, but that’s no comfort when there’s no waves.
The first real flicker of hope comes on Monday the 24th of August. Monday morning, we get a clean offshore from the NE at 35 km/h, and the swell starts to build, around 2 ft from the WSW, but the energy is still weak. That’s not the standout, though. Later that same Monday afternoon, things get interesting. The swell jumps to 5 ft from the WSW, period 7 seconds, and the combined energy hits 206 (moderate). The wind is a cross-offshore from the NNE at 35 km/h, so it’s clean. This is the best on offer, but it’s not perfect—short period swell can be a bit bumpy. Still, for a break that’s fairly consistent and fairly exposed to the SW, this is your window.
Then Tuesday the 25th morning, the swell drops back to 3 ft, energy down to 101, with a cross-shore wind and a chop. Not as good. But Wednesday the 26th morning brings another clean session with a cross-offshore wind from the ESE and 5 ft of swell from the WSW, energy at 194 (moderate). That’s the second best. The wind is light, so it should be tidy. The afternoon of the 26th sees the biggest swell of the run—6 ft from the WSW, period 7 seconds, energy 340—but the wind is a light cross-onshore, and it’s marginal. The short period will make it fat and a bit messy. This one’s only for the keeners who don’t mind a bit of chop.
So, the standout is Monday 24th afternoon: 5 ft, clean, and moderate energy. It’s the best you’ll get. Keep your eyes on the 26th morning too, but don’t expect perfection. The rest of the month is a write-off.

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.
