The Lowdown
Alright, Rusty here again. Let's break down what's cookin' for this stretch of coast.
Gotta be honest, the next two weeks are looking pretty flat. There's a long dry spell right at the start with nothing to surf. The first real chance to get wet is Monday the 31st of August in the morning. A small 5ft NE swell shows up, but it's got a short period around 7 seconds, so it won't have much grunt. The wind is light and cross-off, so it'll be clean. The wave energy is moderate at 268. After that, it's back to nada for days.
The following week is a bust until we get to the 12th of September. On Saturday the 12th in the afternoon, we see a tiny 2ft SW groundswell with a very long period of 17 seconds. The wind is glassy, and the wave energy is moderate at 138. Sunday the 13th is similar, with a 2ft SW swell at 15 seconds, also glassy, and energy at 171. These are surfable, but very ordinary. The long period will make them better for a point or reef, but Polihale is a sandbar, so those long-period swells might just close out. The water temp is a normal 81° for this time of year.
Honestly, there's no standout here. If you're desperate, the Monday morning (31st) with that 5ft NE swell is the biggest we'll see, but it's not good. The best quality is probably the glassy conditions on the 12th and 13th, but the swell is tiny. For a sandbar like Polihale, this is a standard blank run for the area. Don't hold your breath.

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.
