The Lowdown
Alright, Rusty here. Let’s talk about the next 16 days at Rest Bay. It’s a tough stretch, I’m not gonna lie. The surf is looking pretty flat for the foreseeable future, with a whole lot of nothing on the table. The first week is a bust, and the second week doesn’t bring much hope either. The combined swell energy is weak, often in the single digits or low double digits, so there’s just no power in the water.
Wednesday the 22nd kicks things off with a tiny 0.7 ft swell from the west at 9 seconds, and a light cross-on breeze. The water is a notable 68°, which is much warmer than normal for this time of year, so at least the water feels good, but the surf is poor. The next several days are all similar: tiny swells, mostly 0.3 ft to 1.0 ft, and cross-on or onshore wind. There’s a brief period of glassy conditions on Tuesday morning the 28th of July, but the swell is only 1.0 ft, so it’s barely a ripple. The combined energy is a measly 7, so it’s not worth paddling out for.
The dry spell continues all the way through the end of July and into the first few days of August. There is a moment of glassy conditions on the 31st of July with a 0.7 ft swell, and again on the 1st of August with a 0.3 ft swell, but it’s just too small. The best looking wind window is Sunday morning the 2nd of August, with a clean cross-off breeze and a 2 ft swell from the west-southwest at 8 seconds, but the combined energy is only 38. It’s still poor surf conditions.
The swell does pick up a touch on Thursday the 6th of August, with 3 ft to 3 ft from the west-southwest, but it’s onshore wind and short period of 6 seconds, making for messy, choppy conditions. The combined energy reaches 88, still on the low side. It’s not a day for a board, it’s a day for a kite.
Honestly, there’s no standout session here. The whole 16-day window is a washout. The surf just isn’t on offer. If you’re desperate for a paddle, maybe the glassy, tiny morning of the 28th of July gives you a chance to sit on a longboard, but you’ll be waiting for waves that never come. This is a good time to do some tidepooling or go for a swim.
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.
