The Lowdown
Alright folks, Rusty here. Let's have a look at what Polihale has in store for us over the next couple of weeks.
To be straight with you, it's a pretty quiet stretch ahead. For the first ten days, from August 8th right through to the 17th, the surf is gonna be almost non-existent. We're talking flat spells and tiny, weak waves that just aren't worth paddling out for. The combined energy is down in the low double digits for much of that, barely a ripple at times. You'll see a few little bumps here and there, like a 1ft swell from the NNW at 10 seconds on the 9th, but the wave comment pretty much says it all – "poor surf conditions." There's a long gap here with nothing to recommend, so save your wax and don't bother rushing down.
Things finally start to show a tiny pulse of life around the 18th of August. Tuesday morning on the 18th, we get a 2ft swell rolling in from the west with a period of 13 seconds. The combined energy is at 89, so it's still weak. Winds are light from the ENE, keeping it clean. It’s described as "surfable waves but very ordinary conditions," and I’d agree. It’s barely enough for a longboard, but at least you’re not staring at a mirror.
Now, the pick of the whole 16-day window, and the only real standout, is the morning of Thursday, August 20th. We see a bit of a lift. Swell height ticks up to 2ft from the north, with a solid 12-second period, and the combined energy jumps to 172 (moderate wave energy). The real winner here is the wind: glassy, with a slight air from the east. That means clean, smooth conditions at Polihale. Water temperature is a normal 81° for this time of year, so you’re in for a comfortable session. For a little wave, that's about as good as it's going to get in this outlook. The Thursday afternoon holds similar promise with glassy conditions and 2ft swell, but the energy drops a touch to 138.
After that, Friday the 21st and into the weekend, the energy fades back out. The swell drops off and the scores reflect it. So, to sum it up: it’s mostly a flat spell, with the only real chance to wet a line being the morning of Thursday, August 20th. Snag it if you can.

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.
