The Lowdown
Alright folks, Rusty here. Let's have a look at what the next couple of weeks are serving up for us.
Honestly, the start is a bit of a flat spell. We're looking at a few days with barely a ripple, so don't bother paddling out just yet. The first real pulse of energy arrives around Tuesday, September 8th, but it comes with some tricky conditions. By Wednesday morning, September 9th, things start to look a lot more promising.
The standout session for the whole period looks to be Wednesday morning, September 9th. Head to Polihale. We're looking at a clean 5ft swell coming out of the NW with a period of 10 seconds. The wind is dead glassy from the ESE at 6 mph, so expect smooth, clean faces. The combined wave energy is sitting at a decent 433 (moderate energy), so there's some push behind it. This is an exposed sandbar break that's fairly consistent, but be aware it can draw a crowd sometimes. The water temp feels about average for this time of year.
The glassy conditions hold into the afternoon, with the swell easing slightly to 4ft, still from the NW. Another solid window.
After that, the surf turns pretty ordinary again through the rest of the week and into the weekend. There are small, weak swells and mostly cross-off winds, making it tough to find a decent wave.
Looking further ahead, Monday, September 14th afternoon shows some promise again at Polihale. The swell is 4ft from the NE with a period of 8 seconds, and the wind is a clean cross-off from the NE at 6 mph. The combined energy is 205 (moderate). It's not the best of the window, but a solid option for a surf if you're keen.
Beyond that, the second week gets a bit more iffy. Tuesday morning, September 15th, offers glassy conditions and a 4ft NNE swell, but the period is a short 8 seconds, so it won't be holding much shape. After that, it drops off into small, weak surf again. There are no real standout days in that second week, just small, inconsistent pulses.
So, to wrap it up: if you want the best waves of the forecast, be on the water Wednesday morning, September 9th at Polihale. The rest of the window is mostly small and average, with a brief window on the 14th. Keep an eye on it, though; forecasts can change.
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.
