The Lowdown
Alright, let’s talk surf. Cibratel is the only break on the menu, so we’ll focus there.
The start is slow. Tuesday the 25th is a no-go – light cross-on breeze and marginal surf. Not worth it. The combined swell energy is moderate (534), but the wind has it messy.
Wednesday the 26th flips the script. Morning brings a clean cross-off wind from the WSW with a 3 ft SSE swell, but the period is 16 seconds – that’s proper groundswell. Energy is moderate (510) and the waves will have some push. By Wednesday afternoon, it goes glassy with a 4 ft SSE swell and a 15-second period, energy jumping to 755. That’s the real standout: glassy conditions, solid size for a beginner-plus spot, and long-period groundswell. Water temp is 70°, which is a touch warmer than normal for the time of year.
Thursday the 27th keeps it glassy in the morning with a 4 ft SSE swell, 14-second period, and energy at 620. Another clean session. But by afternoon, the wind swings east at 15 km/h, turning it cross-on and choppy – done.
Friday the 28th starts glassy but tiny – 2 ft – barely a ripple. Afternoon sees a bumpy 4 ft swell but with a short 7-second period and cross-on wind, so it’s messy.
From Saturday the 29th through the first week and into the second, it’s mostly small, weak, and poorly aligned. Combined energy drops into double digits and low triple digits, with periods under 10 seconds. There’s a brief window on Saturday the 5th of September and Sunday the 6th where glassy or clean conditions return with a 4 ft ESE swell and 9-second period – surfable but nothing special. After that, it fades.
The clear winners are Wednesday the 26th and Thursday the 27th. That’s where you want to be: clean, glassy, with a solid long-period groundswell. The rest of the 16-day run is mostly small, weak, or wind-affected. For beginners, the Wednesday afternoon glass-off with 4 ft waves is ideal. For experts, this is a quiet stretch.

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.
