The Lowdown

Right then, let's have a look at what's coming up for Polihale over the next couple of weeks. I gotta be straight with you – this stretch is looking pretty flat and ordinary for the most part. There’s a big gap of days where you’d be better off doing something else.

We start off on the 16th of August with nothing doing, just a risk of thunderstorms and a fresh cross-off breeze. That theme carries on through the next few days. Monday the 17th sees a tiny 2ft SW swell with a short 7-second period and only weak wave energy (33). It's poor. Tuesday the 18th is more of the same, just a little bump from the WNW with a longer period (13 seconds) but still barely enough to ride, and the energy is weak (57). Wednesday the 19th is the first tiny glimmer – a glassy morning with a 2ft NE swell, and by the afternoon that swell bumps up to 3ft from the NE with the same glassy conditions. The waves are surfable but very ordinary, with low energy (80). Thursday and Friday follow the same script: small, weak, and nothing to get excited about. Saturday the 22nd is a total flat calm.

Now, if you're looking for the one bright spot in this entire run, it’s on the horizon. Monday the 31st of August is the standout. It’s still a way off, so treat it as promising but not locked in, but the models are showing a proper pulse of groundswell. The morning will see a 3ft swell rolling in from the west with a very long 17-second period. That’s the kind of period that puts real shape and power into the waves, especially here at Polihale, which is a sandbar setup. The combined wave energy is strong at 594, and with a light cross-off breeze, it should be clean. The afternoon holds at 3ft from the WNW with the same 17-second period, and the energy is still very strong (465). This is a day for the experienced crew – that long-period west swell will be working best for those who know the sandbar. The water temp is sitting around 81°F, which is about average for this time of year.

There is one other moment worth a mention: Sunday the 30th of August has a 2ft west swell with an even longer 18-second period, but the energy is much lower (160) and the wind is a light cross-off. It’s surfable but not in the same league as the 31st.

Overall, you’ve got a long blank run from now until the end of the month. Don't hold your breath for anything before that last few days of August. The 31st is your best shot – mark it in the calendar and hope the forecast holds.

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.
