The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming our way for Polihale.
To be honest, it's a quiet start. For the first few days, right through the end of August and into the first days of September, there's barely a ripple. We're looking at a real dry spell with small, weak swell and nothing worth paddling out for. That gap stretches from now all the way to the end of the month.
The first hint of something happens on Monday, 31 August. There's a pulse of swell coming in at 5 ft from the NE, but the period is a short 7 seconds. The combined wave energy hits a moderate 261, so there's some push, but it's not going to be the cleanest. The wind is light and cross-off, so the surface should be alright, but it's only showing for the morning. After that, it drops right back off again.
We get another little blip on Thursday, 3 September. Swell is 3 ft from the NE with that same short 7-second period, and combined energy is 105. It's surfable, but it's ordinary. The best of this quiet spell actually looks like Friday, 4 September. The morning shows 4 ft from the NE, and the wind is glassy. That is clean. The water temp is 81°, which is about normal for this time of year, so no need for a winter suit.
Then things get a bit more interesting. On Thursday, 10 September, we start seeing a build, and then on Friday, 11 September is the standout. The morning shows 4 ft from the NE, and the period stretches to 10 seconds – that's proper groundswell energy. The combined energy jumps to 302. The wind is light and cross-off from the south, which should leave the face nice and clean. The afternoon builds a touch more to 4 ft from the NNE, with energy hitting a strong 378. Winds stay clean.
Friday, 11 September is the one to circle on the calendar. It's not huge, but for a spot that's been so flat, this is the best we've got. The swell direction from the NE and NNE is right in the wheelhouse for Polihale, and with that longer period, the waves should have some real shape and power. Just remember, this is a fairly consistent sandbar break, and crowds are sometimes an issue, so get there early. This is a promising window, but being over a week away, treat it with cautious optimism.
Stay patient, and keep an eye on that Friday.
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.
