The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at what’s on the table for Cibratel over the next couple of weeks. First thing to note, the water here is sitting at 70°, which is a touch warmer than normal for this time of year – that’s a nice little bonus.
The forecast kicks off with a real gem. Thursday morning, August 27th, is the standout of the whole run. It’s dead glassy with zero wind, and we’ve got a clean 4ft swell rolling in from the SSE with a long 14-second period. The combined swell energy is solid at 722, and the report is calling for very good surf. This is the one to circle on the calendar if you can get out there.
After that, things get a bit sleepy for a stretch. We’ve got a few mornings on Friday and Saturday that are glassy, but the swell drops right off to 2ft to 3ft with short period windswell (7-8 seconds). The energy numbers dip way down, like 72 and 60 – it’s surfable but nothing to write home about. Sunday through to the middle of the following week is mostly small and poor, with a lot of onshore or cross-shore wind and choppy conditions. A few clean moments here and there, but the wave heights are tiny, mostly 1ft to 2ft. Not worth paddling out for unless you’re desperate.
Then, after a long flat spell, we get a second window. Thursday morning, September 10th, looks promising again. It’s glassy, calm wind, and we’ve got a punchy 6ft swell from the SSE. The period is short at 7 seconds though, so it’ll be a bit lumpy and fat, but the energy is solid at 586. That one might be a bit much for beginners – over 5ft – but for anyone with a bit of experience, it could be a fun session. The afternoon of the 10th is also good, with 4ft and glassy conditions.
The last bit of the run, around September 11th, has some clean 2ft SSE swell with a long 12-second period on the Friday afternoon, but the energy is moderate at 427. It’s not a standout, but it’s a solid option for a small-wave board.
Overall, the real winner here is Thursday morning, August 27th – glassy, chest-high, long-period groundswell, and the water’s a bit warmer than usual. That’s your session. The second half of the forecast has a few decent moments, but nothing that beats that first day. Keep an eye on that September 10th morning for a bigger, lumpier option if you’re after something with more push.
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.
