The Lowdown
Alright, Rusty here, let’s talk about what’s happening at PKs over the next couple weeks.
The next stretch is looking pretty quiet. From now until about the 20th, we’re in a dry spell – mostly marginal or poor surf because of the conditions. A lot of that will be small or blown out. Things start to perk up a little around the 21st, but it's not until the 22nd that we get a proper clean window.
The date to have circled on your calendar is the morning of Thursday, 22nd August. That's where we get a 3ft S swell with a 14-second period and cross-off wind. The water temp is about 80°, right where it should be for the season. It’s not a huge swell, but it'll be really clean and fun, with only moderate energy (873). On a reef setup like PKs, that is your best session on offer.
Further out, the most promising day is Saturday afternoon, 29th August – and I say promising because it’s a long way off. The wind is going glassy, and we’re looking at a 4ft E swell. It’s not going to be pumping, but with those calm, clean conditions, the waves will have a proper shape. It is the best in terms of quality.
The rest is pretty average. Watch out for that Sunday, 16th August when it gets ugly. That’s a 15ft plus E swell with strong breeze and heavy rain. That’s way too big and messy for a normal paddle. That is kite territory. The other days are mostly 2ft to 3ft swells with moderate breezes coming out of the ENE, keeping the surface clean but the wave size small and the energy low.
Crowds can be an issue here sometimes, but on the smaller weekday mornings it should be quiet.
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.
