The Lowdown
Alright folks, Rusty here. Let’s take a look at what Polihale has got cookin’ over the next couple of weeks.
Right now, we're in a bit of a flat spell. Friday the 17th kicks off with a tiny, clean 2ft W swell, but it’s barely a ripple. Saturday holds similar knee-high dribble. Then Sunday through the middle of the following week, it's pretty much flat with next to no energy. A real bummer – we're lookin' at a solid 10-day gap with nothing worth paddling out for.
Now, keep your eyes peeled on Monday, July 27th. That’s the standout. A solid NE swell pushes through, jumping to 7ft early and holding 6ft into the afternoon. The energy is proper – we're talkin' strong wave energy (553 in the morning). Winds go glassy, and that’s the secret sauce. For the experienced crew, this is gonna be the best run of the forecast. Tuesday the 28th still has decent 5ft NE swell with clean glassy conditions in the morning, but it backs off a notch. After that, the swell fades fast into ordinary waist-high stuff through the end of the month.
Water temp is 80° at the start – bang on average for July.
So, if you’re lookin' to score, pencil in July 27th at Polihale. That’s the 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.
