The Lowdown
Alright, Rusty here. Let's talk about what PKs has in store for you.
Right from the start, the water's sitting pretty at about 80°F, which is totally normal for this time of year – feels like a warm bath. For the first week, the pattern is pretty flat. The wind is holding steady out of the ENE, blowing cross-offshore, so the surface will be clean as a whistle. But the swell, man, it's tiny. Wednesday morning through to Friday afternoon we've got waves around 1 to 2ft from the SSW, with a nice long period of 14 to 18 seconds, but there's no grunt behind them. The combined swell energy is weak, reading as low as (96). It's a reef break here, so those small waves just aren't going to show up with any shape. Unless you're on a log, you're better off waiting.
Don't even think about calling a standout until the second week. The real deal starts to build on Wednesday, August 12th. Wednesday morning we see 3ft of S swell, 18-second period, and the energy kicks up to (790). By Wednesday afternoon, it's hitting 4ft from the south, still with that juicy 18-second period, and the energy is reading (996). That's moderate to strong energy, and the cross-off wind is still blowing clean. For PKs, a long-period S swell like that is exactly what gets this reef working. That window carries into Thursday the 13th, pushing 4ft of S swell with energy around (909). That Wednesday and Thursday are your absolute best bet. The waves will have proper power and shape, but that long period will make the sets a bit more spaced out. It's too big for beginners at that size.
After that, things get weird. Friday the 14th drops back down to 4ft with a shorter period. Then Saturday the 15th of August throws in a 6ft pulse from the east, but with a shocking 7-second period and a fresh 30 km/h cross-off wind. That'll be bumpy and crumbly – no good for a paddle board. That setup, with that wind, is honestly more of a kite-surfing day. The final week from the 17th onward is all small, inconsistent, and weak again. Nothing worth paddling out for there.
So here's the short of it: the first week is tiny and clean but a flat spell. The one and only standout window is Wednesday the 12th and Thursday the 13th of August. That S swell is your chance for the best waves of this whole outlook.
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.
