The Lowdown
Alright, Rusty back at it.
This stretch for Polihale is mostly a snoozer. The first week is tiny, weak, and flat. You’ll see knee-high dribbles with energy levels barely hitting 41, and a long dry spell from August 29th through September 4th with zero surf.
On September 6th, a pulse of long-period west swell shows up – 0.5m, 12-second period, combined energy at 73. Winds are light and cross-off, so it’ll be clean. It’s still just surfable but ordinary.
The best chance comes on September 10th. A bigger NW swell rolls in with combined energy of 414, waves around 1.1m, and a 12-second period. Winds are light cross-off from the south. This is the one window that’ll give you waist-high, clean, lined-up waves. It’s a week and a half out, so don’t book the trip yet, but it’s the only thing worth watching.
Crowds can pop up there sometimes, but with this surf, it’s a safe bet you’ll have the place mostly to yourself.
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.
