The Lowdown
Alright, surfers, Rusty here. Let’s be straight with you about the next couple of weeks. It’s not going to be a wild ride, but there are a few moments where it’ll be worth paddling out. We’re looking at a stretch that starts pretty weak, builds into something decent for a morning or two, and then fades back out. The water’s running a touch warmer than normal for this time of year, so that’s a little bonus.
The Opening Days (August 15-16)
The first couple of days are pretty ordinary. Saturday the 15th is a write-off – light rain and cross-shore wind making a mess of the small, weak swell. Not worth your time. Sunday the 16th is where things pick up. It’s still early in the morning, but the wind goes glassy and we get a bump of east-southeast swell at 6 ft. The period is short, only 8 seconds, so it’ll be a bit crumbly, but the clean conditions will make it rideable. The energy is moderate at 564. It’s a good chance to get some soft, fun waves before the wind turns onshore and chops it up by the afternoon.
A Glimpse of Cleanliness (August 17-19)
Monday the 17th and Tuesday the 18th see the swell drop a bit, down to around 4 ft and 3 ft. The glassy mornings are the only time to go as the afternoons get cross-onshore and messy. These are small, weak days with moderate to weak energy. Wednesday the 19th is smaller again, maybe 2 ft – really just ankle-biters for the longboarders. There’s a clean window, but the swell is just too weak to get excited about.
The Mid-Range Slump (August 20-28)
From the 20th through the 28th, it’s a real struggle. We’re looking at a long stretch of weak surf, mostly under 3 ft, with a lot of onshore wind and poor conditions. The energy drops hard, dipping below 100 at times. You’ll see a few morning glass-offs, but the waves will be small and gutless. From the 21st to the 23rd, there’s a brief pulse of southern swell that pushes the energy back up, but it’s accompanied by light rain and cross-shore winds, and the period is short, so it just looks lumpy and uninviting. By the 24th and 25th, the wind picks up and blows onshore, making things properly ugly. The 26th and 27th are slightly better with some glassy mornings, but the swells are still tiny. This is the part of the forecast where you catch up on other things.
The Final Standout (August 29)
Now, this is the one to keep an eye on. Saturday morning, August 29th, we get a more significant pulse of east swell, pushing 6 ft. The wind goes glassy early, which is huge for a beach break like this. The energy jumps to a strong 538, and it looks like the most promising surf of the whole window. The period is short at 8 seconds, so it might be a bit sectiony, but with that size and no wind, it should be fun and punchy. This is the standout morning to try and get out – it’s a week and a half away, so keep your fingers crossed the forecast holds. The afternoon sees the wind shift onshore and the swell drop, so it really is a morning mission.
The Fade Out (August 30)
The last day of the forecast, Sunday the 30th, shows the swell dropping back down to 4 ft with a short, weak period. Another glassy morning, but the energy is fading fast. It’s a poor reflection of the day before.
So, there you have it. The best bet is clearly the 29th. The rest is a waiting game with a few small, clean morning windows if you’re desperate. Be patient, and keep an eye on that wind.
Rusty.

Information about the Cibratel Surf forecast
The above surf forecast table for Cibratel provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cibratel can be found by selecting the local surf guide option on the grey menu. Our Cibratel 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 (Cibratel) 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 Cibratel 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.
