The Lowdown
Alright, folks, Rusty here. Let’s talk about what’s goin’ down at Polihale. Gotta be honest – the next few days are lookin’ flat and quiet. We’re in for a long stretch of small, weak energy and pretty ordinary conditions. Don’t get your hopes up until the second week.
The first real bit of surf shows up on the afternoon of Tuesday, August 5th, but it’s just a tiny 1 ft swell from the west. The wind is glassy, which is a beauty, but the energy is weak (28) and the wave comment says it all – poor surf. The water is 81°, which is about average for this time of year, so no big deal.
Wednesday through to the weekend stays pretty lousy. We get a few tiny bumps from the NNW and NE, mostly under 1 ft, with periods around 7-8 seconds. The wind stays light or glassy, nice for the view, but the swell just isn’t there. The combined energy stays below 100 for most of it. On the 9th of August, the afternoon sees a bit of a lift with a 4 ft swell from the NE, period 8 seconds, and moderate energy (163). It’s still called “surfable but very ordinary” – not worth paddlin’ out for unless you’re really keen.
The real window starts to open up around the 12th of August. We start seein’ longer period swells from the west, with periods of 14-15 seconds. The energy builds into the low hundreds and then jumps. By the morning of the 19th, we’ve got a 3 ft swell from the west, period 14 seconds, and the combined energy hits 261 – that’s moderate to strong energy. The wind is light and cross-off, and the forecast says “expect good surf conditions.” This is the standout of the whole outlook. The swell direction is from the west, matchin’ the optimum direction for Polihale, and with a 14-second period, that’s a proper groundswell. It’ll be clean and lined up.
Now, if you’re a beginner, 3 ft is fine, but the long period (over 11 seconds) means the waves will have more push and longer gaps between sets. The break is a sandbar, so it might close out a bit, but the wind bein’ light and cross-off is a massive plus. Just keep in mind, crowds are possible here “sometimes,” so don’t expect to have it to yourself.
Take note: from the 4th to the 12th, it’s almost a full week of no real surf. The 19th is the day to circle. It’s far out, so treat it as a promising call, but the forecast confidence is decent for that range.
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.
