The Lowdown
Alright folks, Rusty here. Let's talk about what's coming down the line for this stretch of coast. We've got a slow start, but the back half of the forecast is where the magic could happen. There's a solid run starting on the 25th of August that's got some real potential.
To start, the first proper window is this coming Sunday morning, the 16th of August, at Cibratel. The water's sitting at about 69°F, which feels a touch warmer than normal for this time of year. We've got a clean 6ft swell rolling in from the east with a period of 8 seconds. The energy's moderate (646), but with zero wind and a glassy surface, the setup is going to be super clean. This is a solid beginner-plus wave size, but it's not too heavy for anyone.
After that, things go quiet for a good long stretch. From Sunday afternoon right through to the 24th of August, it's pretty much a write-off. We're talking mostly small, weak swell under 3ft and almost always with some cross-onshore wind. There's a small window on the morning of Saturday the 22nd with some glassy conditions and a 3ft swell, but it's pretty ordinary. Save your energy.
Now, the real standout comes on Monday the 24th of August. The afternoon sees a pulse of swell pushing 5ft from the SSE with a solid 14-second period, and the energy is building strong at 715. It's onshore wind that day, so it's a bit messy, but it sets the stage.
The absolute best on offer is the following morning, Tuesday the 25th of August. We get a clean 4ft groundswell from the SSE with a long 13-second period. The wind is offshore from the WNW at just 3 mph, so the lines will be clean and well-shaped. The energy is pumping at 473. This is a classic point-break style swell, perfect for Cibratel's exposed setup. It won't be too big for intermediates but is a great wave. Expect some crowds though, as this spot can get 'often' busy when the conditions align.
That quality continues through Wednesday the 26th of August. The morning is glassy with a 3ft SSE swell on a 14-second period. The combined energy is very strong at 748. There's a little rain around, but with light offshore winds, the surf will be near-perfect. This stretch from the 25th to the 27th is your window.
There is a final, promising pulse on the last day of the month, Monday the 31st of August. We get a punchy 6ft swell from the south at 8 seconds, with clean cross-offshore winds. The energy is solid at 640. It's a bit of a long-range call, so keep an eye on it, but it looks like a fun way to close out August.
All in all, mark your calendar for the 25th and 26th of August. Those are the days with the best combination of clean conditions and proper swell energy. The rest of the week is a gamble until then.
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.
