The Lowdown
Alright, let’s talk surf. This area is in a flat spell. The first real chance of a wave doesn’t show up until Thursday, July 30th, and even then it’s a marginal call. There’s more than a week of tiny, weak surf to sit through before that. So, don’t be in a hurry.
The only break we’re looking at is Kaolins, an advanced reef that doesn’t break often. It’s inconsistent, so this blank run is normal. The water temp is 69°F, which is a solid 5°F warmer than usual for this time of year – that’s very unusual, so a spring suit or a shorty will be fine.
For the first week, from Saturday, July 18th through Wednesday, July 29th, it’s a write-off. Swell is tiny, around 0.7ft to 1.0ft, with combined wave energy barely registering (9 to 12). The wind is mostly offshore or clean, but there’s no water moving. It’s a total flat spell.
Now, a glimmer of hope. On Thursday, July 30th, the morning shows a pulse of 4ft swell from the WNW, with a period of 9 seconds. The combined energy jumps to a moderate 315. The wind is light from the north, making it cross-off and clean. For a rare-breaking reef like Kaolins, this is the standout window. The swell direction is from the west-northwest, close to its optimum southwest, so it might just wrap in. It’s not huge, but it’s the only time we see a "good surf conditions" note. Thursday morning is the pick.
After that, Friday, July 31st morning has moderate offshore winds and a 3ft west swell (158 energy), but it’s a downgrade from Thursday. The weekend into early August drops back to weak, inconsistent waves in the 2ft to 2ft range.
So, here’s the bottom line: if you’re an advanced surfer and you’re itching for a wave, mark Thursday, July 30th for a dawn session at Kaolins. It’s not a classic, but it’s the only real game in town. The rest of the 16 days is a waiting game.

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.
