The Lowdown
Alright folks, Rusty here. Let's have a look at what PKs has in store for us. It’s a bit of a mixed bag for this stretch, with plenty of days where the ocean’s just not playing ball.
We kick things off with a bit of a slow start. The first surf worth mentioning is on Tuesday the 1st of September, but honestly, it’s a tough one to get excited about. We’ve got a tiny 0.7m south swell with a super long 18-second period. That kind of period on a reef can be tricky, and with the combined energy being weak at best (407), it’s not exactly packing a punch. The cross-off wind from the ENE at 25 km/h will mess with the shape a bit.
Wednesday the 2nd is much the same story – a little 0.9m south swell, still with that long period (16 secs) and moderate energy (479). The wind stays the same, keeping things messy. This stretch is just not delivering the goods.
Now, if you’re a beginner, you might want to be cautious. Swell sizes start to climb, and by the morning of Thursday the 3rd, we’re looking at 1.9m from the east, but the period drops right off to a short 8 seconds. The combined energy jumps up to a strong 1141, but short-period wind swell like this is usually pretty choppy and lacks punch. The wind is a fresh 30 km/h from the ENE, making it a cross-off, but it’s not clean. This run of average to poor conditions continues right through until about the 7th, with the swell fluctuating between 1.5m and 2.0m. The energy is moderate to strong, but the wind is always there, and the conditions are rated as marginal at best.
There is a big spike on the 8th of September. We’ve got a serious 3.0m to 3.5m southwest groundswell rolling in. This is big, powerful stuff. The combined energy is massive – over 4500 (4524 and 4856). That’s expert territory. For the average surfer, this is a heavy, dangerous day. Plus, we've got a cross-shore wind and the risk of thunderstorms, so it'll be a battle just to get out the back. This one’s really more for the big-wave chargers or the kite surfers, to be honest.
The surf drops back down after that, with a few marginal days until we hit a nice little window. Sunday the 13th looks promising. The morning shows a clean 1.7m east swell with an 11-second period and moderate energy (819). The wind is a light 15 km/h from the ENE, keeping the surface clean. This is the standout: the conditions are expected to be very good, and the size is manageable for a good range of surfers.
Tuesday the 15th is another highlight. The morning is a bit average, but the afternoon looks absolutely magic. The swell is a small 0.9m from the southwest, but the period is a very long 20 seconds, and the energy is a solid 600. The wind dies right off and goes glassy. That’s about as perfect as it gets for a reef like PKs when a long-period south swell sneaks in. Expect some beautiful, clean lines.
Wednesday the 16th also looks clean. The morning offers 0.9m from the SSW with a long 18-second period and light cross-off winds. The afternoon is similar, with 0.9m from the SW and light winds. The conditions are expected to be very good to good.
So, to wrap it up: the first week is mostly a write-off for good surf. The absolute best bets are the afternoon of Tuesday the 15th for that glassy, long-period treat, and the morning of Sunday the 13th for a cleaner, slightly bigger east swell. Keep an eye on the big swell on the 8th, but only if you’re an expert.
Rusty.

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