The Lowdown
Hey everyone, Rusty here. Let’s break down the next couple of weeks at Cibratel. It’s a mixed bag, but there are a few windows that’ll get your blood pumping if you time it right. The water is sitting at 70°, which is a touch warmer than normal for this time of year – not a bad thing at all.
We kick off on Wednesday, August 12, but honestly, don’t get too excited. The early days are a bit flat and messy. Wednesday morning has a small 4ft SSE swell, but it’s short period at 12 seconds and the wind is cross-on from the ENE at 6 mph. The wave energy is weak (360), and the conditions are just marginal. Thursday and Friday aren’t much better – the swell fluctuates between 3ft and 4ft, with light cross-on winds. The energy picks up a bit on Thursday afternoon (501), but it’s still not clean.
The first real glimmer comes on Saturday, August 15. The morning looks glassy with a calm wind and a 4ft SSE swell at a nice 13-second period. The combined energy is moderate (482), and for a moment, it’s clean. But don’t get too comfortable – by afternoon, the wind swings to the east at 12 mph and turns it into a choppy mess.
Sunday, August 16, is where it gets interesting. The morning is absolutely glassy with a solid 6ft easterly swell. The period is short at 8 seconds, so it’s a bit windswell-ish, but the energy is strong (576) and the conditions are pristine. That’s a standout session for the week – clean, punchy waves for anyone who’s comfortable in overhead surf. Afternoon gets messy again, so get out early.
Monday, August 17, offers a brief reprieve with a glassy morning and a 4ft ESE swell at 9 seconds – clean but small (219 energy). After that, things go quiet again from Tuesday through to the end of the week. The swell drops to 2ft to 3ft, winds are mostly cross-on, and the energy is pitiful (30 to 96). It’s a real lull.
Now, looking ahead to the second week: Sunday, August 23, shows a pulse of 5ft SSE swell but the wind is onshore from the ESE at 9 mph, making it a messy, marginal affair. The energy is strong (657), but it’s not clean.
The real highlight of the whole forecast is Wednesday, August 26. The morning is glassy, with a solid 8ft southerly swell at 10 seconds. The combined energy is massive (1876) – that’s powerful, serious surf. This is for experienced surfers only; it’s going to be heavy and clean. The wind is light from the SSW, so expect those long, glassy walls. That’s the day to circle on your calendar, but keep in mind it’s a week and a half away, so it’s a promising long-range call.
The next day, Thursday, August 27, cleans up again with a glassy morning and a smaller 3ft SSE swell at 11 seconds – a nice recovery session.
Overall, the best on offer is the Sunday morning the 16th for a fun, clean session, and the Wednesday the 26th for the big, powerful stuff. The rest of the time, you’ll be waiting for the wind to cooperate.
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.
