The Lowdown
Alright, grab your board and listen up. Rusty here, and I’ve got to be straight with you – this outlook for Kaolins (Big Island) is a tough one. We’re looking at a 16-day window that starts with a whole lot of nothing. The truth is, for the first ten days, from now right through to around the 26th of August, the surf is just not there. We’re talking tiny, weak scraps – nothing worth paddling out for. It’s a long, flat stretch, and honestly, that’s just how it goes here sometimes; the ocean shuts the door for a spell.
But don’t give up hope yet. There is a light at the end of this tunnel. The one and only real standout in this whole forecast lands on Saturday the 29th of August. The morning session is looking promising. We’ve got a solid 6ft swell rolling in from the WNW, with a moderate 9-second period. The wave energy is strong, clocking in at 910, which is the most juice we’ll see all period. What’s got me excited is the wind: a clean, cross-off breeze from the east. That should groom that reef nicely for the advanced crew. Saturday the 29th is your day.
Keep in mind, Kaolins is an advanced reef break that’s inconsistent, so it doesn’t fire every day. When it does, it can get a bit of a crowd, so don’t expect to have it to yourself. The water temperature is running at a touch warmer than normal for this time of year, around 69°F, but that’s neither here nor there when the waves are good.
After that Saturday morning peak, things drop off again. There’s a brief chance on Sunday the 30th afternoon with glassy conditions and 4ft of swell, but the energy is weak (123), and the forecast isn’t calling it a classic.
So, to wrap it up: save your energy for the 29th. The rest of the time, you might as well wax your board and wait.
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.
