The Lowdown
Alright, let’s talk about the next couple of weeks at Polihale. Right now, things are flat. There’s nothing worth paddling out for on Monday or Tuesday. In fact, we’ve got a real dry spell on our hands. From August 31st all the way through to the morning of September 8th, it’s basically a write-off. Sure, there’s a tiny blip of 0.7 ft on Tuesday afternoon, but that’s not going to get anyone excited. The wind is mostly light and cross or cross-off, but with no swell to work with, it’s a non-starter. This is one of those stretches where you’d be better off checking the forecasts again tomorrow.
Now, things start to look a little more interesting on the morning of Wednesday, September 9th. We’ve got a 4 ft swell coming from the north, with a short, punchy 8-second period. The energy is moderate, and the wind is a clean cross-off from the south. It won’t be perfect, but it’s surfable. The afternoon cleans up with a 3 ft north swell and a light offshore from the southeast. The energy drops a bit, but the wind turns gentle offshore and the waves are clean. It’s not a standout session, but it’s the first real chance to get wet in over a week. Keep your expectations in check.
After that, we slip back into a quiet stretch. There’s a tiny 3 ft east-northeast swell on Friday, September 11th, but it’s weak and the period is a short 7 seconds. Just a dribbler.
The one that catches my eye is the morning of Sunday, September 13th. We get a 2 ft swell from the west-northwest, but here’s the kicker: that period is 15 seconds. That’s a long-period groundswell. The energy is moderate, and the wind is a light cross-off from the east. This is the kind of swell that can wrap in and offer some clean, lined-up waves, especially at a place like Polihale that’s exposed to the northwest. The water temperature is about average for this time of year. If you can get out in the morning, that glassy, clean surface with that long-period pulse could be the best of the whole outlook. Just remember, long-period swells can break a bit straight at beach breaks, but Polihale’s a sandbar setup, so there might be some fun ones.
The rest of that week is tiny and glassy, but with waves under 2 ft, it’s not really worth suiting up. So if you’re keen, aim for the 9th for a solid average day, or hold out for the 13th when that long-period groundswell pushes through. It’s not a blockbuster forecast, but there are a couple of windows.

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.
