The Lowdown
G’day, Rusty here, and I gotta be straight with you—this is a tough one for Polihale. The whole 16-day window is looking pretty flat, with only a few small windows where something might be rideable. We’re staring at a long stretch of days with barely a whisper of swell, and even when it does show up, it’s not exactly gonna get the heart racing. The first real chance of anything surfable doesn’t even pop up until Tuesday the 8th of September, and even then it’s marginal. Before that, we’re looking at a solid 5 days of nothing—just flat, clean conditions with no wave energy to speak of. The combined swell energy is a big fat zero (0) for most of those early days.
Now, for the first standout, you’ve got to look at Tuesday the 8th of September. A swell finally shows up from the NW, pushing 7 ft in the morning. That’s a solid size, but it’s also a short-period swell at 9 seconds, so it’s gonna be a bit lumpy and disorganised. The wind is coming from the SW at 12 mph, which is cross-shore, not ideal. The combined energy hits 711 (moderate to strong), but the conditions are described as marginal, with a cross-chop. This is more of a kite surfing setup than a clean paddle session, to be honest. The afternoon drops to 5 ft, still NW, but the wind picks up a cross-shore component.
The real highlight, the best of the lot, is Monday the 14th of September. We’ve got glassy conditions in the morning, with a 5 ft NE swell at 8 seconds. That’s not a big period, but the clean, glassy wind will make it a lot more user-friendly. The combined energy is 241 (moderate), and it’s the only day in the whole forecast that gets a “expect good surf conditions” label. The water temperature is about 80°F for the first mention, which is pretty normal for this time of year—no big anomaly there.
Other than that, the 16th and 17th of September offer some knee-to-waist high NE swell (4 ft to 4 ft), but with periods around 7-8 seconds and glassy conditions, they’re just average. The crowds at Polihale can be “sometimes” busy, but with this kind of lacklustre forecast, I wouldn’t expect many people out.
All in all, if you’re desperate, Monday the 14th is your best bet. Otherwise, wait for a better forecast.
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.
