The Lowdown

Alright, folks, it’s Rusty here. Let’s be straight with you: the next two weeks and change are looking pretty bleak at Polihale. We’ve got a long dry spell ahead, with a few tiny windows of something rideable, but nothing to get the heart racing. This is one of those periods where you might be better off checking the forecast again later.

The water’s sitting at 81°, which is just about spot-on for this time of year, so you won’t need a thick suit. The issue is the swell, not the temps.

We start things off on Monday the 17th with absolutely nothing. No swell to speak of, and the wind is a cross-off breeze, which is a shame because it would be clean. That’s a wasted day. Tuesday isn't much better, with tiny WNW swell around 1ft and a short 13-second period, and the energy is weak (57). Just not worth getting wet.

The middle of the week remains flat to almost flat. Wednesday and Thursday have a bit of NE wind swell in the 2ft range, but the period is way too short, under 8 seconds. Thursday morning is glassy, but there’s just no push to it. The combined energy is weak (60). It’s just a tease.

Friday the 21st is another dud. By Saturday the 22nd, we start to see a slight pulse. Saturday afternoon a WNW swell shows up at 3ft with a more decent 13-second period, and the energy jumps to a moderate 269. That could be the first real chance, but overall it’s still just ordinary. Sunday’s got a cross wind which will chop it up a bit, and the swell drops back.

Now, here’s the one small standout: Monday the 24th in the morning. We get a push of NE swell up to 5ft, the energy is a moderate 243, and the wind is a light cross-off from the ENE, which should keep it reasonably clean. It’s not big, but it’s the most surfable we’ve seen. After that, we fall right back into the doldrums. Tuesday and Wednesday are back to nothing, and the rest of the week is a mix of tiny swells and flat spells. There's a bit of WNW groundswell trying to show up around the 29th, but it's just not enough.

The following week is more of the same. A small W swell pops up on Sunday the 30th at around 4ft, but the wind kicks up and the period drops to 9 seconds. It’s another ‘maybe if you’re desperate’ kind of day. The run continues to look poor, with low energy and short-period swell. The last day of the forecast period on Tuesday, September 1st does have a longer period W swell at 14 seconds, but it’s only 2ft. That’s a lot of period for no power.

So, overall, don’t plan your life around this. The only day that even comes close to a green light is the morning of Monday the 24th for a slightly better wave. Otherwise, this is a good time to get the gear serviced or find another hobby for a couple of weeks. It’s a flat spell, but that’s how it goes sometimes. Keep the hope alive; it won't be like this forever.

Rusty, out.

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.
