The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for Polihale.
Honestly, the next week and a half is a bit of a slow burn for the sandbar here. We’ve got a long stretch of small, mostly unrideable surf from now until around the middle of the month. The best things to keep an eye on are two separate windows, one mid-month and another proper standout at the very end of the forecast period.
The first real glimmer comes on Sunday the 14th. The morning glass-off is looking magic with clean conditions as a 5ft swell rolls in from the NE. It’s only a short period (8 seconds), but with that clean glassy surface, it’ll be a fun one for a log or a mid-length. That afternoon the wind shifts cross-on, so get it while the getting’s good in the AM.
But the true standout, the one worth circling on the calendar, is the final two days of the run, Sunday the 20th and Monday the 21st. This is where it gets interesting. A solid, long-period groundswell fills in from the WSW with a period of 14 seconds, bringing a nice, clean 3ft wave. The wind is light and offshore from the SE, so Polihale should be clean and lined up. The wave energy is getting up there, clocking in at a solid (317–218) range, so it’ll have some push. Given the long period, this is a classic setup for a point or reef, and this sandbar should handle it just fine. Expect some proper shape and longer waits between sets. It’s an expert-friendly size, but because it’s not too tall and the wind is sweet, it’ll be user-friendly too.
Crowds are a possibility here, they can show up sometimes when it’s this clean. Water temp is sitting at about 80°, which is right on the money for this time of year.
So, get ready for a quiet start, a quick hit on Sunday the 14th morning, and a promising finish on the 20th and 21st. Keep your eye on those last two days.
Rusty.

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.
