The Lowdown
Alright crew, Rusty here. Let’s talk about what’s cooking at Cimaja.
We’ve got a solid run of swell on the cards for the next two weeks, but the wind is gonna be the main character. Most days we’re looking at cross-onshore or cross-shore breezes, which will keep things a bit lumpy and chopped up. The water’s sitting around 82°F, which is pretty average for this time of year, so boardies or a spring suit will do you fine.
The first real standout window is Sunday, September 3rd. Thursday morning the conditions glass right off – we’re talking a light 5 km/h wind from the SSW, glassy surface, and a clean 4ft swell from the SSW with a 15-second period. That’s a proper groundswell with good energy (733 combined energy), and it’s gonna offer some well-shaped lines. For a reef break, that long period will really wrap in nicely and give you some proper walls. It’s not huge, perfect for intermediates, and the crowd factor here can be “sometimes”, so don’t be shocked if it’s not empty.
Another big mention has to be Tuesday, September 12th through Thursday, September 14th. We see the swell building back up solidly. Specifically, Thursday morning, September 14th, has that clean 8ft swell from the SW with a 17-second period and very light 5 km/h winds from the south (slight air). That’s serious power (3165 combined energy). That’s expert-level size, definitely not for beginners. That long period groundswell on a reef like this will be firing, but with that cross-onshore element and size, you’ll want your wits about you. The wind won’t be perfect but the swell quality will still be there.
The rest of the period, from late August right through to mid-September, sees a mix of waist-to-head-high swell but with those onshore and cross-shore winds making it choppy. Nothing to get too excited about.
So, the pick of the month? Without a doubt, that Thursday morning, September 3rd glass-off. But if you want more size and power, keep your eye on September 14th as the promising, if less certain, long-range standout.
Stay safe out there.
Rusty.

Information about the Cimaja Surf forecast
The above surf forecast table for Cimaja provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cimaja can be found by selecting the local surf guide option on the grey menu. Our Cimaja 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 (Cimaja) 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 Cimaja 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.
