The Lowdown
Alright, Rusty here, checking in on the local surf outlook for the next couple of weeks.
Right off the bat, we’ve got a bit of a flat spell to start. The first real chance to paddle out is on Thursday, the 13th of August. Before that, there’s a couple of days of small, bumpy swells that aren't really worth a mention.
The standout for the whole period is shaping up to be Thursday morning, the 13th of August, down at Cibratel. We’re looking at a clean 3 ft swell from the SSE, but the real story is the period—13 seconds. That’s proper groundswell energy, and it’s pushing a solid 400 units of combined swell energy. The wind is glassy, absolute magic. That combo is about as good as it gets for a clean, workable wave. It’s a beginner-plus spot, so it’s a great time for an intermediate to get some clean lines.
Then there’s a promising pulse on Monday the 17th of August. The morning is looking solid again with glassy conditions. The swell bumps up a touch to 4 ft from the ESE with a 9-second period. The energy is moderate at 274, and with that glassy wind, it’s going to be a fun, clean session. The water temperature is about average for the time of year, so no need for a thick suit.
The rest of the week after that gets a bit messy. We get a few more glassy windows on the 18th and 19th, but the swell drops off hard. By the 19th, we’re down to 2 ft and the energy is weak (53). The 21st of August shows a spike in swell, hitting 5 ft from the SSE with a 10-second period and a strong energy reading of 527, but it’s coming in with light rain and a cross-on wind. The afternoon of that same day might clean up into a glassy 3 ft SSE swell, which could be a decent second wind.
From the 22nd of August onwards, it’s pretty much a write-off for quality surf. The swell gets tiny, the wind turns onshore, and the energy drops off. It’s a long stretch of poor conditions. You’d be looking at a full week of flat, choppy water before anything might show up again around the 25th. That Tuesday morning on the 25th has a whisper of hope with a glassy 3 ft, but the period is a short 7 seconds, so it’ll be a weak, crumbly affair.
Overall, your best bet is locked in for Thursday the 13th and Monday the 17th. Get out there and get it while the getting’s good.

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.
