The Lowdown
Alright folks, Rusty here. Let’s dig into what we’ve got on the horizon for the next couple of weeks.
Right off the bat, there’s a big hole of nothing. We’re looking at a stretch of flat, poor conditions that kicks off from now all the way through to the end of August and into the first week of September. Nothing doing at all for the paddle crew. You’d need a kite to get any fun out of this, but even then, the wind isn’t clean enough.
The real story starts to shift around Monday, the 31st of August. We get a little pulse of swell showing up, a clean 5 ft from the NE with a short period of 7 seconds. The energy’s moderate, sitting at 268. Winds are light and cross-offshore from the ENE, which should keep things tidy. It’s a small window, though, because by Tuesday afternoon it’s already fading into the dirt.
After that we hit another dry spell for several days. The ocean just goes quiet again. Not much to report until Monday the 7th of September. That afternoon a little 3 ft NNE swell rolls in, 8-second period, moderate energy at 117. It’s surfable but pretty average, with a light breeze keeping the surface clean.
Now, the one that stands out, the one you want to pencil in: Friday the 11th of September. This is the pick of the run. Polihale should wake up to a clean 4 ft NNE swell, period still short at 8 seconds, but the energy jumps up to a solid 323 – that’s moderate to strong. Morning winds are absolutely glassy – dead calm. That means perfect, clean lines peeling down the sandbar. The swell direction isn’t the perfect NW the spot likes best, but with those conditions and that energy, it’s going to be fun for an advanced crew. Crowds are sometimes an issue here, so don’t expect to have it all to yourself, but the quality will make it worth it.
A few days after that, things look ordinary again. The 12th and 13th of September offer some marginal 3 to 4 ft waves from the NE, but the comment says "very ordinary". It’ll be rideable but nothing to write home about. The 14th of September has a tiny 3 ft NNE swell with weak energy – barely a ripple.
So, bottom line: the best on offer is without a doubt the morning of Friday the 11th of September at Polihale. Glassy, clean, decent energy. For now, enjoy the time off, because the swell is taking its sweet time.
Rusty.

Information about the Polihale Surf forecast
The above surf forecast table for Polihale provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Polihale can be found by selecting the local surf guide option on the grey menu. Our Polihale 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 (Polihale) 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 Polihale 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.
