The Lowdown
Right, Rusty here again with the look-see for Cibratel. We’ve got a bit of a slow build ahead.
The first proper surf lands on Monday, August 10th, but it’s a mess. A strong 7ft swell from the S, with a 13-second period and a big combined energy reading of 1873, but it’s got a cross-on wind from the S at 15 km/h, so it’s choppy and ugly. The water’s sitting at about 70°, which is a touch warmer than usual for this time of year.
Tuesday the 11th and Wednesday the 12th are pretty flat and weak. Swell drops to 5ft and then 4ft, still from the SSE, but with onshore and cross-onshore winds, the waves will be bumpy.
Thursday morning the 13th is where we get our first real clean wave. A small 3ft swell from the SSE, but the wind is glassy calm. The combined energy is at 307. It’s not big, but it’ll be the cleanest you’ll find for a while. Friday morning the 14th looks similar, with glassy conditions and a 3ft SSE swell.
The weekend from the 15th sees the swell fade a bit, and the wind gets a little more tricky. Still surfable, but not great. Sunday the 16th has a glassy start with a tiny 3ft SE swell, but it fizzles out by the afternoon.
Then we hit a major lull from Monday the 17th through the end of the week. Swells are tiny, under 3ft, with very weak energy. There’s a couple of glassy periods on Tuesday the 18th, but the waves are only around 2ft to 2ft from the SSW and S, which is hardly worth the paddle.
The one true standout is way out at the end, on Tuesday morning, August 25th. That’s over two weeks off, so it’s a long shot, but it looks unreal. We’re looking at a solid 4ft swell from the S, with a 13-second period, and the combined energy is a strong 880. The wind is glassy calm. The forecast says "expect very good surf conditions". That morning window is the best on offer. It gets a little onshore by the afternoon, but that morning session is the one to hope for.
So, the next week and a half is for the small-wave carve board. The real highlight is that Tuesday morning the 25th – a long-range promise, but a great one.

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.
