The Lowdown
Righto, let’s have a look at what’s on the cards for Cimaja. It’s a reef break that’s very consistent, so there’s always something in the water, and it’s exposed to the swell. We’ve got a solid run of groundswell coming through over the next couple of weeks, but truth be told, the wind’s going to be a bit of a pest for most of it.
The water’s sitting at 28°, which is about average for this time of year, nothing too unusual there.
We start off on Monday the 10th with a decent 6ft to 7ft south-southwest groundswell, but it’s straight on-shore wind. That’s going to make it pretty gutless and messy, not worth paddling out for. Tuesday the 11th sees the swell push up to 8ft, but again, cross-on winds are going to chop it up, making for a rough afternoon.
Wednesday the 12th drops off a bit in size, still cross-on, still average. Look, the first stand-out in this whole run is Thursday morning the 13th. The swell holds at 8ft from the south with a very long period of 17 seconds, and we get glassy conditions. That’s a proper window. The combined wave energy is pumping at 3328, so there’s plenty of push. This is going to be the pick of the first week for experienced surfers, as 8ft is a solid size for a reef. It might be a touch much for beginners, but for anyone with a bit of time in the water, it’s going to be clean and powerful. It’s a Thursday, so the crowds shouldn’t be too heavy, though being consistent, expect a few locals out for sure.
Friday the 14th and Saturday the 15th are a bit of a let-down after that, with lighter swells and the cross-on wind creeping back in. Sunday the 16th through to Tuesday the 18th sees a real drop-off; the energy dips right down into the hundreds, barely any punch in the waves. There’s a bit of a gap there where it’s just too weak to get excited about.
Then we start looking at the second week. Wednesday the 19th of August looks big, with the swell jumping back up to a thumping 10ft from the south-southwest, but the wind is cross-on. That’s a lot of power, and combined energy is around 4583 to 4868, but the on-shore component is going to make it a real battle. That’s expert territory, or maybe even more interesting for kite surfing than a clean paddle session.
Now, the second true stand-out shows up on Thursday the 20th. The morning is glassy again, with a strong 8ft south-southwest swell and a period of 16 seconds. The energy is 2854, so it’s got grunt, and with no wind, it’s going to be clean. This is another top call for the experienced crew. Once that wind shifts cross-on in the afternoon, it will lose its shine, so the early session is the only one that matters that day.
From Friday the 21st onward, the runs are a bit more hit-and-miss. The swell drops a bit, and we get some cross-shore winds. There’s a decent push on Sunday the 23rd with 8ft and a long 18-second period, but again, the cross-on wind stops it from being a classic. It’ll still be worth a look if you’re hanging for a wave, but it won’t be the perfection of the Thursday mornings.
So, to sum it up: the best waves on offer are the Thursday mornings, the 13th and the 20th. Get up early for the glass-off and enjoy some solid, clean groundswell. The rest of the time, you’ll be fighting the wind.

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.

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.
