The Lowdown
Alright, folks, Rusty here with the lowdown on Polihale for the next 16 days.
It’s a dry spell at the start. From Monday, July 20th, right through Friday, July 24th, there’s no surf worth talkin’ about. Five days of flatness. The water’s about 80°F, which is normal for the season.
Then, on Saturday, July 25th, the afternoon brings a 6ft swell from the NE, period of 8 seconds, and the combined energy hits 371 (moderate). With a light cross-offshore breeze from the ENE at 6 mph, it’s clean and fun. Sunday, July 26th keeps that same energy, with 5ft from the NE, same clean wind. This is the best stretch. The swell is solid, not too big for most, and the wind is treatin’ it right. Polihale is a sandbar, so expect some peaks, but the light wind will keep it tidy. Crowds are possible, so get there early.
Monday, July 27th still has some 4ft to 5ft leftover NE swell, but the period drops to 7 seconds, so it’s a bit more jumbled. Still surfable, but not as crisp. By Tuesday, July 28th, the swell drops to 4ft and the wind turns cross-on, so quality goes downhill.
The rest of the week into early August is mostly small, weak, and inconsistent. A few glassy mornings, like Wednesday, July 29th, with a tiny 3ft from the NNE and zero wind, but it’s barely a bump. The second week is a total dud, with nothing over 3ft and lots of flat spells. The standout is definitely Saturday, July 25th and Sunday, July 26th. That’s your window.
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.
