The Lowdown
Alright, folks, Rusty here. Let’s talk about the stretch ahead at Polihale. It’s a bit of a mixed bag, with a long flat spell to start, but there’s some life in the second week.
We’re looking at a real slow start. From Thursday afternoon, July 29th, all the way through to the morning of Friday, August 7th, there’s basically nothing worth paddling out for. That’s a solid nine-day gap with no decent surf on offer. The data shows waves are too small or the conditions are just ordinary, so you’re better off saving your wax for later.
The first real glimmer of hope comes on Friday, August 7th. The afternoon shapes up with a clean 3 ft swell rolling in from the west, with a period of 13 seconds. That’s a long-period groundswell, which will bring in some nice lines. The wind is light and cross-offshore from the east, keeping things tidy. The combined energy is a solid 225 (moderate wave energy), so there’s some push behind it. This is a good option for the advanced crew out at Polihale (sandbar). It’s a fairly consistent spot, though it can be a bit inconsistent, and the crowds are sometimes an issue. Worth noting, the water temp is sitting at a normal 80° for this time of year.
But the real standout window is Sunday, August 9th. Both the morning and afternoon sessions are looking prime. We’re seeing a consistent 3 ft swell from the west, with a period holding steady at 12-13 seconds. The wind is light and cross-offshore from the east-northeast, keeping the surface clean. The combined energy jumps up to 259 in the morning and 239 in the afternoon (moderate wave energy). This is the best on offer. It’s a true shoulder-hopper for the experienced surfers, and the conditions are as good as we’re going to get.
Moving into the second week, things get a bit more inconsistent but still have potential. The afternoon of Monday, August 10th, looks glassy with a 3 ft west swell and a long period of 13 seconds. The energy is up there at 358 (moderate wave energy), which is promising. Then Wednesday, August 12th, has a morning session with a 3 ft short-period swell from the northeast (8 seconds) and a clean offshore wind from the southeast. The afternoon on the 12th brings a 2 ft west swell with a very long period of 16 seconds, and the energy is 345 (moderate wave energy). That’s a serious groundswell, but it might be a bit too straight for the sandbar, so keep that in mind. It’s all a bit less certain out that far, but the signs are there.
Overall, the best call is to pencil in Sunday, August 9th, and keep an eye on the afternoon of August 10th and 12th. The rest of the time, you’re waiting it out.
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.
