The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Rest Bay over the next couple of weeks.
Honestly, I’ve got to be straight with you—this is a grim run. The water is sitting at 69°, which is a staggering 8° warmer than what we’d usually expect for this area at this time of year. That’s very unusual, and it feels like summer has turned the dial up, but it’s not doing us any favours out the back.
The short-term outlook is a dead loss. The first few days of the period offer nothing rideable. Monday the 3rd and Tuesday the 4th have tiny, weak swell with poor winds, and the wave energy is barely registering (43 to 72). It’s totally flat for a good stretch here. The whole first week is a write-off, with very poor surf conditions across the board. The wind is mostly onshore or cross-onshore, often moderate to strong, and the swell heights are tiny. There’s a brief moment on Sunday the 9th morning where it’s glassy, but the swell is only 2ft – you’d be bobbing around on a lake.
This blank run continues right through until the middle of the month. From the 10th to the 15th, the swell is practically non-existent, with wave energy dropping to single digits or low double figures. It’s truly a quiet spell, and for this area, that’s a pretty normal, frustrating summer pattern.
Now, we do have a glimmer of hope right at the tail end. The standouts of the whole 16-day window are the mornings of Sunday the 16th and Monday the 17th. On Sunday the 16th morning, we’ve got a 4ft swell from the west, with a clean cross-offshore ESE wind at 12 mph. The combined energy pushes up to 178 (moderate). Then on Monday the 17th morning, it’s a similar story: 5ft from the west, again with that clean cross-offshore ESE breeze at 12 mph, and energy at 221 (moderate). These are the only two sessions that look genuinely worth a paddle. The swell is big enough to be fun, but not too big for an intermediate, and that wind direction should keep the surface tidy. The crowds are often here, so expect company, but the quality on offer makes it worth the squeeze.
The rest of the second week is a letdown, dropping back to tiny, weak waves. If you’re desperate for a splash, pin your hopes on that 16th and 17th, but don’t hold your breath for anything before that.
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.
