The Lowdown
Alright, this is Rusty. Let’s have a look at the surf prospects for PKs, a reef break that’s beginner-friendly and fairly consistent, with a preference for swell from the south.
Right now, the water temp is sitting at 80°, which is right where it should be for this time of year – nothing unusual there, just your standard warm bath.
The overall picture is a bit of a slow burn. We’ve got a lot of days ahead where the surf is small and the conditions are just kind of *there*. The first real standout, and the best on offer, is shaping up to be Thursday the 13th of August. Morning session brings a clean 4 ft S swell at a long 16 seconds, packing moderate wave energy (1061). That’s proper groundswell, and for a reef, those long lines should wrap in nicely. The wind is a cross-off from the ENE at 15 mph, which will keep the faces clean. It’s not huge, but it’s the most promising window in the near term.
The afternoon of the 13th drops off a little in quality, and from Friday the 14th through the weekend, the swell fades and the wind picks up. By Saturday the 15th and Sunday the 16th, we’re looking at fresh breezes from the NE at 19 mph, with weak, short-period swell. The surf is basically a write-off—small, bumpy, and messy. The one bright spot late Sunday the 16th is a brief offshore wind from the NE at 22 mph, but the swell is only 2 ft, so it’s not really worth paddling out for.
Next week stays pretty quiet. Monday the 17th and Tuesday the 18th have a risk of thunderstorms and the swell stays small. On Tuesday morning the 18th, there’s a weird spike of 6 ft WNW swell, but it’s only 6 seconds period—that’s pure wind chop, not worth a second look for a reef.
Then we hit a dry spell. From Wednesday the 19th all the way through to Sunday the 23rd, the swell is tiny, mostly under 3 ft, with weak energy numbers (under 400). The wind is a steady cross-off, but the ocean is just flat. The crowd factor at PKs is “sometimes,” but with waves this small, you’ll have the place to yourself.
Finally, the long-range starts to flicker with some promise. Monday the 24th of August sees a bump in S swell, 3 ft to 3 ft, with a long 18-second period and moderate energy (672 to 780). It’s still marginal, but the direction is right. The real hope comes on Tuesday the 25th and Wednesday the 26th. Tuesday morning delivers 4 ft S swell at 16 seconds, strong energy (1210), and Tuesday afternoon hits 3 ft S swell with a very long 20-second period and very strong energy (1476). Wednesday the 26th peaks with 4 ft to 5 ft S swell, 17 to 18 seconds, and energy readings in the strong range (1775). That’s a proper groundswell pulse. The catch: it’s a long way out, so keep an eye on it. The wind stays cross-off, which is clean, but for an expert reef, that long-period S swell will be delivering some solid, well-shaped lines.
Overall, don’t get your hopes up for the next week. The standout is Thursday the 13th for a fun, clean session, and the end of the month (the 25th and 26th) looks like the real deal if the forecasts hold. For now, the board stays in the car.
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.
