The Lowdown
Alright folks, Rusty here. Let’s have a look at what Polihale’s got cookin’ over the next couple of weeks.
Right off the bat, I gotta be straight with you – the first week is a real struggle. We’re lookin’ at a massive dry spell. From now until Friday the 14th, the surf is basically flat or close to it, with weak, un-rideable energy. The combined energy is barely registering (0 to 52). There’s nothing to get excited about. You’d be better off stringin’ up a hammock.
Things finally start to stir on Friday morning, August 14th. We get a pulse of 4ft from the NE with a short, crumbly 7-second period. The combined energy jumps to a moderate 142, and the wind is light cross-off, keepin’ it clean. But honestly, it’s not great – the period is short, so it’s gonna be a bit fat and weak. It’s just enough to wet your wetsuit, but I wouldn't call it a standout.
The real glimmer of hope comes on Tuesday morning, August 18th. That’s our standout. We’ve got a clean 3ft swell from the NNE with a 9-second period and a combined energy of 257 – that’s proper moderate energy pushin’ in. The wind is light and offshore from the SSW, which is perfect for Polihale’s sandbar setup. It’s a fairly consistent spot, so you should score a few waves. Water temps are about average for this time of year, so no surprises there.
After that, the rest of the window is pretty ordinary. We get a few more small pulses, like a 2ft long-period swell from the SW on the 21st (127 energy), but it’s not enough to really light up the break. The end of the window on the 24th shows a bit of 4ft NE swell again, but it’s the same short-period story.
So, bottom line: suffer through the first week of flatness, then circle Tuesday, August 18th on your calendar. That’s your best shot for a decent session. Otherwise, it’s a quiet outlook for Polihale.
Stay salty,
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.
