The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a bit of a slow start, but there’s some glassy windows to hunt for. The first few days are pretty ordinary with onshore winds and marginal surf, so you'll want to be patient. The best of the lot is shaping up to be Wednesday morning.
Cibratel is the only spot on the radar. It’s a very consistent, beginner-plus friendly beach break, exposed to the swell. The water is sitting at 70°, which is a touch warmer than normal for this time of year.
Sunday, August 9th is a write-off. Cloudy with a light cross-on S wind and only 3ft of SSE swell, poor conditions. The afternoon is no better with marginal surf and questionable tides.
Monday, August 10th sees a bump in size but the wind is still messy. The morning has light rain and onshore SE wind, with 4ft SSE swell (moderate energy at 408). By the afternoon, the wind picks up to 9 mph from the S, making it cross-on and choppy with 6ft swell (strong energy at 1696). That’s too big for beginners and the quality is poor.
Tuesday, August 11th stays marginal. Light rain and onshore winds all day with 4ft SSE swell (moderate energy around 550-560). Nothing to write home about.
Wednesday, August 12th is the standout. The morning is looking mint – some clouds, a glassy NW breeze at 3 mph, and 4ft of SSE swell (moderate energy at 383). This is your window. Clean, glassy conditions with a solid 12-second period. It’s the best on offer, no question. The afternoon turns cross-on again, so morning is the move.
Thursday, August 13th morning has another glassy window with a calm SW wind, 3ft SSE swell (moderate energy at 236), and a 12-second period. Clean surf, but smaller. The afternoon brings onshore wind and a longer 15-second period, but the quality drops.
Friday, August 14th morning is glassy again with a calm ENE wind, 3ft SSE swell (moderate energy at 251). Clean, small, and fun for the longboard or a fish. The afternoon goes cross-on.
Saturday, August 15th is back to poor surf with light cross-on winds and 3ft SSE swell. Not worth paddling out.
Sunday, August 16th morning has a glassy ENE breeze with 3ft SSE swell (low energy at 156). Surfable but ordinary. The afternoon fades.
Monday, August 17th through Tuesday, August 18th sees a shift. Swell direction moves to SE and then ESE, with periods dropping to 9-10 seconds. Heights around 4ft (moderate energy around 240-270). Winds are cross to cross-on, so it’s marginal.
Wednesday, August 19th afternoon brings a pulse of 5ft ESE swell (moderate energy at 557), but the wind is onshore from the SE. Marginal.
Thursday, August 20th morning is glassy again with a calm SSW wind, 3ft ESE swell (low energy at 187). Clean but small and ordinary.
Friday, August 21st through Sunday, August 24th is a long stretch of poor conditions. Swell drops to 2ft to 3ft with very short periods (5-8 seconds), weak energy (40-128), and onshore or cross-on winds. The sea is mostly choppy and messy. The glassy morning on Saturday, August 22nd has only 2ft of S swell – barely worth a splash.
Monday, August 24th afternoon brings a clean cross-off wind from the WSW with 2ft ESE swell, but it’s very ordinary.
So, to wrap it up: Wednesday morning, August 12th is the one to circle. Glassy, clean, 4ft SSE swell with a good 12-second period. Thursday morning, August 13th and Friday morning, August 14th are also worth a look for clean, smaller waves. After that, it’s a long wait for anything decent.
Stay patient, keep an eye on the wind, and I’ll see you out there.

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.
