The Lowdown

Alright, Rusty here again. Let’s break it down for the imperial crew.

The next couple weeks are looking pretty slim, with a big gap of nothing worth chasing early on. Starting from the 14th of September through to about the 25th, we’ve got a whole lot of flatness and mediocrity. The first few days – Monday the 14th through Wednesday the 16th – are technically surfable with 3 ft of NE swell and glassy conditions, but the combined energy is only 139, which is weak, and the period is 8 seconds, so it’s just mushy and uninspiring.

From Wednesday afternoon the 16th onward, the swell vanishes and the wind turns bad, leaving us with blown-out dribble and zero recommendations. That’s over a week of nothing.

Then, around the 27th of September, we finally see a pulse. Sunday morning brings a 6 ft N swell with the combined energy jumping to 853 – that’s strong and punchy. The period is 10 seconds, so there’s some power there. The catch is the wind: cross-onshore from the north at 6 mph. It’s not a total write-off, but it’ll mess with the face. Polihale is an exposed sandbar on the west side (Kauai), so it’s wide open to that north swell. That 6 ft is pushing into advanced territory, so beginners should sit this one out. Crowds can pop up there, so keep your eyes open.

Monday the 28th drops back to around 4 ft but the energy stays high at 760. The period drops to 9 seconds, so it’s a little less clean. The wind is onshore from the NW at 6 mph, which is going to mess things up again.

Later on the 28th, a 15-second NW groundswell sneaks in, but it’s only about 2 ft and the wind is cross-onshore, so it’s more of a tease than anything. That long period would be better at a reef or point, but with the wind and size, it’s not worth the drive.

The real standout here is the early Sunday session on the 27th of September at Polihale. 6 ft of N swell with serious energy, but you’ll be dealing with that cross-onshore breeze. If the wind eases, it’s your best chance in two weeks. Otherwise, it’s a lot of waiting around.

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.
