The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s cookin’ for Polihale. Gotta be straight with you – this stretch of sandbar is gonna be a tough one over the next 16 days. The waves are gonna be real quiet for a long while, and there’s only a couple of moments that might get the heart pumpin’.
We’re looking at a long, dry spell to kick things off. From the start, right through the first week, it’s flat. Tiny lumps and bumps, but nothing you’d paddle out for. The wind is light, sometimes glassy, but with no swell, it’s just a pretty day at the beach. The water temp is sittin’ around 81°F, which is about average for this time of year, so no worries there.
The first real sign of life doesn’t show up until Monday afternoon, August 17th. That’s a big one – a 8ft swell from the NE, but the wind is howling onshore from the NNW at 12 mph. The combined energy is a massive 1377 (very strong), but that wind is gonna chop it up real bad. It’s a no-go for paddle surfing; if you’ve got a kite, the setup might look more interesting.
Then, on Tuesday, August 18th, we get our best shot. The morning brings a clean 5ft swell from the NNE with a short period of 8 seconds, and a light offshore wind from the S at 9 mph. The combined energy is a solid 411 (moderate to strong). This is the standout for the whole window. The water will be clean, and the power is there. It’s a bit too big for the groms, but for the experienced crew, this is the one to circle. The afternoon backs off to 3ft, still clean, still good.
After that, it’s back to the slumber. The rest of the third week stays tiny, with a few small pulses of swell, but nothing that gets the score above ordinary. There’s a flash of a 7ft NE swell on Monday, August 24th, but with a cross-shore wind and a short period, it’s likely a messy, borderline situation.
So, to sum it up: you’ve got a whole lot of flat, a couple of days of promise, and one clear winner on Tuesday, August 18th. That’s the day to be on it.

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.
