The Lowdown
Alright, let’s get into it. I’m looking at the charts for Rest Bay and, frankly, it’s a pretty quiet spell ahead. We’ve got over a week of tiny, weak surf on the cards before anything gets interesting.
Wednesday 22nd through to Friday 1st August is a long, flat stretch. For the first several days, we’re looking at waves barely above 0.3 ft – 0.3 ft, with combined energy values as low as 1 or 2 (very weak). The wind is mostly onshore or cross-onshore, so conditions are messy. It’s not a good time to paddle out. From Saturday 25th afternoon, we see a tiny bump to 2 ft–4 ft, but the period is short (4–7 seconds) and the wind is still cross-onshore, making for choppy and poorly-shaped surf. The combined energy picks up to 283 (moderate) on Sunday 26th afternoon, but the quality isn’t there.
Things start to liven up around Saturday 1st August. We get a pulse of 4 ft swell from the WSW with a period of 10 seconds and combined energy around 245 (moderate). But the wind is straight onshore from the WSW at 15 mph, so it’ll be bumpy and hard to get a clean ride. Not a standout day for the average surfer.
Sunday 2nd August brings the biggest swell of the whole run – 5 ft from the WSW, period 7 seconds, and combined energy at 249 (moderate). The wind swings to a light cross-shore from the NNW in the afternoon, only 3 mph, so there’s a window for relatively clean conditions. This is the best on offer. For intermediate surfers, it’s manageable but short period might make it a bit lumpy.
Then from Monday 3rd August onward, the swell eases back to 3 ft and the wind goes onshore again. A small window on Wednesday 5th August morning looks clean with a light cross-offshore breeze from the SE, but the swell is tiny at 1.0 ft. Not worth the trip.
Overall, I’d say hold your fire. The best chance to get wet is Sunday 2nd August afternoon at Rest Bay – it’s not perfect, but it’s the closest thing to a session we’ve got. After that, it’s back to small and windy.

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.
