The Lowdown
Alright crew, Rusty here. Let’s talk PKs and what’s coming down the pipe for the next couple of weeks. We’ve got a slow start, so don’t be in a hurry.
We’re looking at a real quiet spell to begin with. From now through about the 17th of September, it’s pretty much flat or close to it. Swell is tiny, 1ft to 3ft, with a steady cross-off breeze. The wave energy is weak to moderate, reading in the low hundreds (66 to 476), and every report is calling it poor or marginal. Not worth the wet suit.
Things perk up a little around Friday the 18th. The swell jumps to 6ft on Friday morning, but it’s short-period stuff at 9 seconds from the east. The energy climbs to 996, which is solid, but the quality is still just marginal. It’s a bit of a messy setup.
The real standout window, the one you’ve been waiting for, starts on Friday the 25th of September. Friday afternoon is where it’s at. The swell drops back to a clean 3ft from the SSW, and the wind goes completely glassy. That’s the key. The combined energy is a healthy 517, so there’s enough push. It’s going to be glassy, clean, and beautiful. That’s your best session of the whole forecast.
That glassy, clean trend holds right through the weekend and into the next week. Saturday the 26th and Sunday the 27th both have glassy conditions with a 2ft to 3ft SSW swell and periods stretching out to 14 to 18 seconds. That’s real groundswell. The energy sits in the moderate range (306 to 418), but the quality is good. It’s not big, but for PKs, a reef break that breaks fairly consistently, these are the days to be out. The water is a warm 80°, which is about average for this time of year.
If you can only pick one, make it Friday the 25th afternoon. That glassy wind and clean 3ft SSW swell with that long period are a dream. It’ll be perfect for a beginner-friendly wave. Just be aware PKs can get a bit crowded sometimes.
After that, the conditions hold into Monday the 28th and Tuesday the 29th. More glassy, clean conditions with similar SSW swell. The energy actually peaks a bit on Tuesday (597), so that’s a strong backup plan. It’s all about clean, lined-up waves on a reef.
So here’s the deal: the first week and a half is a skip. Then a spike on the 18th, but the real magic is from the 25th onward. Glassy winds, long-period SSW groundswell, and clean surf. That’s your window.
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.
