The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Polihale over the next couple of weeks. I gotta be straight with you – it's gonna be a real quiet stretch for a while.
We're starting off with a whole bunch of days where there's just nothing worth paddling out for. From Monday the 10th right through the weekend of the 16th, we're looking at tiny waves and poor conditions. Swell energy is almost non-existent (32 to just 611) and even when a little bump shows, the conditions are poor. There is a bit of a spike on Sunday the 16th with an 8ft swell from NNE, but that's coming in with 37 mph winds and moderate rain – that's a mess, not a session. The water temp is sitting at a warm 81°, which is pretty normal for this time of year.
Things start to look a little less grim from Monday the 17th. We get some waist-high waves pushing through, and importantly, the wind turns offshore from the SE. On Monday afternoon the swell bumps up to 5ft from WSW with a short period of 7 seconds and the combined energy climbs to 188. The wind is a gentle offshore, so the surface will be clean. It's not world-class, but it's surfable after a long wait. Tuesday the 18th morning is glassy with a 3ft swell from the west, but that'll be weak and pretty ordinary. Nothing to set the world on fire, but you'll get a few if you're keen.
Then we get to the standout. If you can wait, the real winner is Friday the 21st of August. That morning, the stars line up. We've got an offshore wind from the ENE at just 3 mph making it glassy, and a 2ft swell from the SW with a very long period of 16 seconds. This is groundswell, folks. The energy reading is a solid 218. That long period means the waves will have good shape and power for their size, and the glassy conditions will make it feel like a sheet of glass. This is the best session of the whole forecast by a long shot. After that it drops back to small, clean but ordinary surf through the rest of the period. So, if you're patient, the 21st is your day.
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.
