The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' over the next couple of weeks.
Right off the bat, it's a bit of a slow start. The first few days are pretty much a write-off for any real surf. We've got a gap from now until Tuesday the 8th of September where there's just nothing worth paddling out for. Hold your horses.
The first real action kicks off Tuesday the 8th of September at Polihale (Kauai). This is an exposed sandbar break that's fairly consistent, and it's about to light up. We're looking at a solid 7ft of swell coming from the W, wrapping in with a period of 10 seconds. The combined energy is strong (808), so there's plenty of grunt behind it. The morning starts with rain showers and a cross-off breeze, but by the afternoon it clears up with a gentle cross-off wind. This is a big one, and with chest-to-head high waves, it's for the advanced crew only. The water temperature is pretty standard for this time of year, nothing unusual to report.
Wednesday the 9th of September is the standout. The morning is absolutely glassy – zero wind, calm as a lake. The swell drops a touch to 4ft from the NW, still with a 10-second period, and moderate energy (273). This is clean, perfect, overhead surf. The crowd factor is "sometimes" here, so you might have a few friends out, but with conditions this good, it's a no-brainer. Get a dawn patrol session in.
After that, Thursday the 10th and Friday the 11th see the swell drop off dramatically. The 2ft to 2ft waves are just not enough to get excited about, even if the wind is light. There's a long-period (15-16 second) groundswell showing on Friday and Saturday the 11th and 12th of September, but it's tiny (2ft), so it's just a tease. That long period will make the little waves stand up a bit, but it's not going to be a proper session.
From the 13th of September through the 20th, it's a pretty sad run. The swell stays tiny, mostly under 3ft, with poor conditions and cross-off winds. There's a brief moment on the afternoon of the 16th with a 4ft NE swell and a glassy surface, but at 7 seconds period, it's weak and messy (140 energy). It's surfable, but just barely.
The bottom line: the first week holds the gold. That window from Tuesday afternoon through Wednesday is your best bet. After that, it's a long, flat stretch. Don't hold your breath for the second week.
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.
