The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Polihale over the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough stretch. We’re lookin’ at a long, dry spell that starts now and runs all the way through to the morning of Friday the 21st of August. That’s over a week with pretty much nothing worth paddling out for. The energy is flat, with the combined swell energy barely tickin’ over into double digits some days, like a weak 56 (moderate energy) on Wednesday the 12th, but the wave heights are tiny – 1ft to 1ft. It’s frustrating, but for this area, a blank run like this ain’t unusual. The water temp anomaly is about average for the time of year, so at least the dip won’t be a shock to the system.
Then, finally, on Friday morning the 21st of August, we get a little pulse. The northeast swell shows up at 4ft, but the period is a short 6 seconds. That’s windswell, and it’s not gonna have much shape or power behind it – the combined energy is 186, which is moderate. The wind though, oh boy, it’s glassy. Dead calm. That’s a major positive for Polihale (Kauai). That glassy surface will make even these ordinary waves look a bit more inviting. The swell direction is from the NE, which is the optimum direction for this spot. It’s a fairly consistent break, so you might get a few runners. Be aware, crowds are possible here sometimes.
The best of the whole outlook is that Friday morning. It’s the only real stand-out, even if it’s not a classic. The swell is clean, the wind is perfect, and it’s the only day with a score that isn’t a zero. The afternoon stays glassy, but the swell drops to 4ft. Saturday morning the 22nd is smaller again at 3ft and still glassy, but the energy is weak (81). After that, we’re back to flat, tiny waves and more onshore or cross-onshore winds through the end of the month.
So, if you’re desperate, mark your calendar for Friday the 21st of August. It’s not gonna be a day for the history books, but with glassy conditions and a little bit of NE swell, it’s your only real shot. Any other day, leave the board at home.
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.
