The Lowdown
Right, listen up. Rusty here, and I’ve had a proper look at the charts for Kaolins. Gotta be straight with you – it’s a grim outlook for the next couple of weeks. This is a reef break that’s rated for advanced surfers only, and it’s inconsistent, so we don’t expect waves very often. Well, it seems the forecast is living up to that reputation.
We’ve got a long, long dry spell ahead. From now, through the end of August and into the first days of September, it’s basically a write-off. There’s no surf worth paddling for. We’re talking day after day of onshore or cross-onshore winds, mostly moderate to fresh, and lumpy, choppy conditions. The swell is small and weak, with the combined wave energy barely getting out of double digits for most of it – you’re looking at readings like 22, 38, 50, all in that poor bracket. The water temp is sitting about 68°, which is about average for this time of year.
Then around the 26th of August, the swell tries to kick up, with a 7ft SW swell showing moderate energy of 610, but it’s hammered by onshore winds. The same story continues through the end of the month – bigger swell, but completely blown out with cross-onshore winds. That 8ft swell on the 29th of August has energy over 1000 (994 and 1094), but with fresh cross-onshore winds, it’s not for paddling. If you’re a kite surfer, that setup might look interesting, but for a surfer, it’s junk.
We finally get a glimmer of hope right at the very end of the forecast. On Thursday the 3rd of September, we see the winds shift offshore from the NE. It’s a clean, moderate offshore breeze which is a big positive. The swell is only a 5ft SW swell with a short period of 7 seconds and weak energy of 213, so it’s not going to be pumping, but it’s surfable. The conditions will be clean for the advanced crew.
Honestly, that’s the only standout of the whole run, and it’s still a long way off. For the next week and a half, the only good news is that Kaolins is a reef break, so when the swell is this small and weak, the lack of waves just means the water’s flat. Don't hold your breath.
Rusty.

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