The Lowdown
Right then, let’s see what we’ve got for the next couple of weeks. Honestly, it’s a grim picture for the most part. We’re looking at a long stretch of very small, weak swell with a lot of funky cross-shore wind. The best we can hope for is a few fleeting moments of clean, glassy conditions, but the waves themselves will be tiny. There’s a real gap here with hardly anything worth paddling out for.
The standout window, if you can call it that, is Wednesday the 9th at Polihale. The morning starts clean with a light cross-off breeze from the SSW, and a small 4 ft NW swell, period of 8 seconds. That’s a short-period swell, so it won’t have much grunt, but the wind is light. The real gem is the afternoon. The wind goes completely glassy, calm with a 4 ft NW swell, period 9 seconds. The combined energy is moderate at 210. The water temperature is a balmy 80°, which is about average for this time of year. For a few hours, it’ll be as smooth as a lake. The break is a sandbar, so it’s not the most reliable, but with those conditions, it’s the best shot we’ve got.
The rest of the week is a write-off. Thursday the 10th drops to 2 ft, and by the afternoon a risk of thunderstorms rolls in. It’s all downhill from there, with tiny waves and poor surf conditions through the 11th, 12th, and 13th. There’s a little blip of a 2 ft, 16-second period groundswell on the morning of the 11th and 12th, but that’s a very long period for a tiny wave at a beach break like Polihale. It’ll likely break too straight, offering little shape.
The second week is the same story. The 14th, 15th, and 16th are all about knee-high dribble. The combined energy is mostly in the weak range, like 31 on the 14th afternoon, or 43 on the 16th. A few of these mornings are glassy, like the 15th and 23rd, but the swell is so small (2 ft, 2 ft) it’s barely surfable. The 17th of September sees a slight uptick in swell to 3 ft, period 11 seconds, with a combined energy of 228, but the wind is a cross-off at 9 mph, which is not ideal. By the 20th, there’s a 2 ft NW swell with a period of 11 seconds, but it’s just ordinary.
The 23rd of September, the last day in the window, shows a clean, glassy morning with a 2 ft NNW swell, period 10 seconds, and a combined energy of 97. It’s a weak, tiny wave, but it’s clean. For a long-range call, it’s promising but not a bet I’d take to the bank.
Alright, if you’re a beginner, the swell never gets above 5 ft, so you’re safe from anything too big, but there’s nothing to ride anyway. The whole setup is more interesting for a kite surfer than anyone with a paddle. We’ll just have to wait for the next system.

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.
