The Lowdown
Alright folks, Rusty here. Let’s get straight into what’s happening with the surf over the next couple of weeks.
Well, to be honest, it’s a pretty bleak stretch on the whole. For the first ten days, we’re looking at a whole lot of nothing. There’s a long gap from the start all the way through to the 20th of August where the waves are just too small or flat to get excited about. You’ll see a few days with tiny little bumps, but nothing that’s worth paddling out for. It’s just one of those quiet runs.
Then, finally, things start to show a little pulse around the 20th of August. Our best bet, and really the only standout in this whole 16-day window, is Polihale on the morning of the 20th of August. That Thursday morning, we’ve got a clean 2 ft swell rolling in from the southwest with a very long period of 18 seconds. That’s proper groundswell energy, and the combined energy reading is 168 (moderate), which is a solid step up from the flat spell. The wind is glassy from the ENE at just 3 mph, so it’ll be butter-smooth. The water temperature is about average for this time of year, so nothing out of the ordinary there. This is a sandbar setup so it’s exposed, but that long period (over 15 seconds) can make it a bit straight at times, though the glassy conditions will make it clean. It’s a fairly consistent spot, but it can get crowded sometimes, so keep that in mind.
The other little pulse comes in the afternoon of the 22nd of August with a 2 ft southwest swell at 15 seconds and clean cross-off winds. The energy is moderate (113), but it’s not as strong as the 20th. It’s surfable, but nothing that’ll blow your mind.
So to wrap it up: if you’re patient, the morning of the 20th of August is the one to aim for. It’s not huge, but it’s clean and has some grunt. Everything else is a write-off or too far out to rely on. Keep an eye on it, but don’t hold your breath.
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.
