The Lowdown
Alright, Rusty here, let's talk about PKs. This forecast is a real rollercoaster, so brace yourselves. The next week is basically a write-off, with a big stormy swell early on that's totally unsurfable. After that, we've got a long wait for things to clean up.
We're starting off Monday the 7th with a proper dud. A massive 10ft SSW groundswell is on the way, with a long 15-second period, and it's packing some serious energy (6664). But it's blowing 31 mph from the east, so it's a total mess. This one's for the kite crew, not paddle surfers.
Tuesday the 8th is still no good. Swell drops to 8ft but it's cross-on with fresh SW winds, making it lumpy and choppy. The water temp is a normal 81°, but you won't be in it long enough to care.
Wednesday the 9th through to Saturday the 12th is a real flat spell. Swell drops below 3ft, and while the winds start to clean up, there's just no energy. The combined energy falls to between 84 and 410, which is weak. You'll be looking at small, weak lines, if anything.
Then, finally, things start to look up. From Sunday the 13th onward, the swell is tiny and inconsistent. But hold on.
The real standout, the one worth marking on your calendar, is a two-day window starting Thursday the 17th of September and Friday the 18th of September. On Thursday afternoon, we see a pulse of 2ft SSW groundswell with a 20-second period, but it's the energy that's the real story – 556, and it's building. The wind is a light, offshore 6 mph from the east, meaning clean conditions. Then Friday the 18th is the best day. Swell pushes up to a clean 3ft from the SSW, with a 17 to 18-second period. The combined energy jumps to 677 on Friday morning, and by Friday afternoon the wind goes glassy. That's a magic window for PKs. This is a reef break, and with that long-period swell, expect proper lines and better shape, but be mindful of the gaps between sets. For a beginner-friendly spot like this, the size is perfect.
The second week has a few other clean but small days around the 19th and 20th of September, but nothing beats that Friday session. Saturday the 19th and Sunday the 20th stay clean with 3ft and 3ft swell, but the energy drops off. It's still worth a paddle if you missed the best day.
After that, the forecast fades into very small, ordinary conditions again through the 22nd, with the swell dipping to 2ft and 2ft. It's a long wait for that one good shot, but that Friday the 18th looks like the real deal.

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.
