The Lowdown

Alright, let’s get into it. We’re looking at Cibratel, and honestly, the first few days are a bit of a write-off. Friday the 21st and Saturday the 22nd are pretty average at best, with onshore winds and small, weak swell. The water is sitting at 71°, which is a solid 5° warmer than usual for this time of year – that’s a pretty notable anomaly, so you’ll be in for a warm one if you get in.
Things start to look a little more interesting on Sunday the 23rd. The morning goes glassy with a light 3ft swell from the SSE, but it’s a short period at 10 seconds, so it’s not going to have much grunt. The combined energy is weak (164). It’s surfable, but don’t expect fireworks.
Now, the first real standout appears on Tuesday the 25th. The morning looks absolutely pristine. We’ve got a 4ft swell from the SSE, a long period of 14 seconds, and glassy conditions with a light NW wind. The combined energy is moderate (509). This is a proper groundswell. The direction is right on the money for Cibratel, and with that offshore wind, it should be clean and lined up. It’s a solid call for the more experienced surfer.
Wednesday the 26th morning is also a good shout. The wind is dead calm, glassy, with a 3ft swell from the SSE and a 12-second period. The energy is moderate (307). It’s a smaller window, but it’ll be fun.
By the end of the month, things go quiet again. The 28th through the 31st see the swell drop to tiny 2ft or less, with weak energy. Not much to get excited about.
Then, we jump ahead. The next real highlight is a long way off, on Friday the 4th of September. The morning brings a 3ft swell from the SSE, but with a very long period of 14 seconds and a clean cross-off wind from the NNE. The combined energy is strong (721). This is another promising long-period groundswell. It’s far out, so keep an eye on the charts, but it could be a cracker.
A couple of things to note: Cibratel is exposed and very consistent, so it won’t stay flat forever. The Tuesday the 25th morning is the best of the first week, and the Friday the 4th of September morning is the best bet for the second week. The swell is over 5ft for a bit on Thursday the 3rd of September, with onshore winds, so that’s more for the experienced crew.

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.
