The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ at Polihale over the next couple of weeks. It’s a bit of a slow burn, so don't get too excited just yet.
Right off the bat, we’re looking at a stretch of very quiet days. Through Thursday the 10th and right into the middle of next week, the wave heights are tiny, mostly below 3 ft. The combined wave energy is weak, barely cracking 100 (maxing out around 145 on Sunday morning). The water temp here is about what you’d expect for this time of year, so a normal tropical bath. The saving grace is that the wind is mostly glassy or light, especially those mornings. But honestly, the surf is just too small and weak to get excited about – it’s a real flat spell lasting from now right through to about the 16th.
We start to see a little pulse on the 12th and 13th, with that swell nudging up to 3 ft from the NE, and the energy just touches 145 on Sunday the 13th morning. It’s “surfable but ordinary.” You might catch a knee-high wave on a longboard if you’re desperate, but there’s nothing to rush out for.
Then, after that, we hit another lull from the 18th through the 23rd. Swell drops back to 1 ft to 2 ft, energy figures in the teens and twenties – it’s basically a lake. You’d be better off with a paddleboard than a surfboard. It’s a pretty big gap of poor to no surf.
Now, here’s the standout – and it's a long-range promise, so keep an eye on the charts. On Thursday the 24th of September, things shift. The swell direction swings around to the WNW, and the period jumps to a lengthy 21 seconds. That’s proper groundswell. The energy ramps up to 291, and into Friday the 25th it hits 348. The wave height is still modest at 2 ft, but that long period will give it some real push and shape. The wind stays clean and light offshore or cross-off. It’s a classic Polihale combo: that NW swell lines up nicely for the sandbar, and with the wind out of the east, it’ll be glassy. This isn’t for beginners – the period is long, so the sets will be powerful for the size, and the rip can pull. But for the experienced crew, the 24th afternoon through the 25th morning looks like the only real window of fun in the whole 16 days. Crowds can be a thing out here, but on a Thursday and Friday with the swell this small in size, it shouldn't be too bad.
So, hang tight. The next week and a half is a write-off. The end of the forecast window is your shot.
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.
