The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for the next couple of weeks at Rest Bay.
Alright, I'm gonna be straight with you – the next week and a half is looking pretty grim. The wind is all over the shop and mostly onshore, making a mess of things. It's a tough run for surfers.
The only real glimmer of hope is a tiny window on Thursday the 24th of September. That morning, we've got a light southeast breeze coming offshore, which will clean things right up. The swell is small, coming in at about 3ft from the WSW, with a weak combined energy (93). It's not going to be big, but it'll be glassy and clean. If you're desperate for a paddle, that's your moment. Just be aware that the crowds at Rest Bay are often a factor, so you won't be alone.
The following week is a write-off. The wind stays strong and messy, and the swell is either too small or blown out. There's a bit of a spike on Sunday the 20th of September, with an 8ft swell from the WSW and a combined energy of 768, but with a strong 22 mph onshore wind, it's going to be a washing machine. Not for paddle surfing. If you've got a kite, that setup looks more interesting.
Further out, on Monday the 28th of September, the wind finally goes offshore from the ENE, but the swell is tiny at 1ft from the WSW. There's not enough push to ride anything, but it's a sign that things might be changing.
So, to sum it up: don't hold your breath. Thursday the 24th morning is the only decent option, and even that is a small, clean wave. Everything else is a battle with the wind.
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.
