The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a tough stretch ahead for Rest Bay. We’re lookin’ at a long, long dry spell. The first week of September is a write-off, honestly. The first sign of any kind of life, and I’m bein’ generous here, doesn’t show up until Monday the 14th, and it’s barely a pulse.
We’ve got flat, messy conditions, onshore winds, and tiny swell for days on end. The water temp is a notable 67°F with a massive anomaly of 6°F warmer than normal at Rest Bay, so it’s very unusual and feels like a bath.
Monday the 14th morning is the only window where we might see a wave. The swell is a weak 2ft from the WSW, with a gentle cross-offshore breeze from the ESE. It’s clean, but the combined energy is a measly 59 (weak energy). It’s surfable, but just barely. Don’t get your hopes up.
After that, it’s back to tiny, weak, and mostly choppy for the rest of the forecast. There are some glassy mornings on the 17th and 20th of September, but with swell heights of 2ft and 1.0ft, and combined energy readings in the teens, you’d be better off takin’ a nap.
Honestly, this is a proper blank run. There’s no standout session, no big swell to get excited about. For this area, unfortunately, a stretch like this is more normal than you’d hope. It’s just one of those times to clean your gear, watch the cams, and wait for the next forecast to change.
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.
