The Lowdown
Alright crew, Rusty here. Gotta level with you – the next couple of weeks are looking pretty flat for the most part at Polihale. There’s a real dry spell coming up, so if you’re itching to get wet, you’ll need to be patient.
For the first eight days, it’s a ghost town. From Thursday, August 6th, right through to Thursday, August 13th, we’ve got nothing but tiny, weak leftovers. We’re talking about surf that’s barely a ripple, with combined energy readings sitting in the low teens and single digits (13-36). The wind is mostly light, and there are a few glassy windows, but with no swell to speak of, it’s a flat calm. The water’s sitting at a warm 81°, which is pretty normal for this time of year.
Things start to look a little less hopeless from Saturday, August 15th. The swell finally shows a pulse, with a small 2ft groundswell rolling in from the West, with a period of 12 seconds. The combined energy is starting to climb into the double digits (98-116). It’s surfable, but the conditions are still described as ‘very ordinary’. The wind is a steady cross-off from the ENE, which is a bonus, but the waves are just too small to get excited about. For a spot like this, that’s more of a longboard or a log session.
Now, if you’ve got the patience of a saint, the real standout is peeking out on the horizon. Mark your calendars for Thursday, August 20th. We’ve got a proper spike in energy. The swell direction swings around to the SW, with a period of 15-16 seconds – that’s a long-period groundswell, folks. The combined energy jumps right up to 205-210. The forecast is calling for 2ft of swell, but with that kind of period and energy, it’ll have more push than the numbers suggest. The wind is light and cross-off, promising clean conditions. This is the one to wait for, but don’t hold your breath; it’s a long way out.
The following Friday, August 21st, the energy backs off a bit, but it’s still surfable. There’s a weird mix with a 3ft, 6-second windswell from the NE, but the period is too short to be any good. Stick with the 20th if you can.
Rusty, signing off.

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.
