The Lowdown
Alright, let me break it down in feet for you. This is Rusty with the surf for Polihale, West Kaua’i.
Overall, the next couple of weeks are pretty sleepy. We’ve got a slow first half with some tiny, weak swell and only a few clean windows worth thinking about. The latter part of the second week looks a bit more interesting, but don’t expect a pulse.
Polihale is looking pretty sad to start. Tuesday afternoon we’ve got a messy 5ft NW swell with a short 8-second period and cross-off winds. The energy is low and it’s a write-off. Wednesday sees a tiny 4ft swell from the NNW with okay period (9s) but by Thursday morning it’s down to 2ft with very low energy. There is a lovely glassy session Wednesday afternoon with a 4ft, 10-second NW swell and dead calm wind, but it’s just not much wave. The water is a normal 80°.
From Friday the 11th right through to the middle of the next week, it’s flat. The swell drops to 2ft to 3ft with weak energy almost every day. Not worth the drive.
The standout window shows up on Thursday the 17th and Friday the 18th of September. Thursday morning gives us a 3ft NW groundswell at 10 seconds with moderate energy and glassy conditions. That’s a clean, workable longboard wave. It gets even better Thursday afternoon with a 3ft NW swell and low wind – still glassy with decent energy. The wind direction aligns with the optimum NW for this sandbar break. It will be clean and uncrowded. That’s your shot.
After that, the 21st of September shows a tiny blip, but with next to no energy. Not even close to decent.
So, the only real option in the next 16 days is Polihale on the 17th and 18th of September. Small but glassy and clean – a proper session for a mellow board.
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.
