The Lowdown
Right, grab a coffee, mate. Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
First up, the water’s sittin' at a balmy 80°, which is pretty much spot on for this time of year. No surprises there.
Now, the forecast. Look, I’m not gonna sugarcoat it – the first week is a bit of a write-off. We’ve got a long dry spell here from the start through to the 26th of July. There’s just nothing doing. Tiny lumps, no energy, and the wind is mostly cross or cross-off, which is fine for a flat day, but it ain’t gonna get you wet. It’s a bit of a bummer, but it happens.
The real action, what little there is, kicks off on Sunday the 26th of July. That’s the standout window. Polihale (Kauai) will finally see some life. We’re looking at a 5ft NE swell, with a period of 8 seconds. The wind is a light E cross-off, which should keep the surface clean. The combined energy of all swells directed here will be moderate (346). It’s a nice, honest little pulse. The wave comment says to expect good surf conditions, and I’d agree. It’s the best on offer.
That Sunday and Monday the 27th of July will be the pick. Monday morning sees the swell drop a touch to 5ft, still from the NE, with that same light E cross-off. Still clean, still surfable. The energy drops to 229, but it’s still a solid session.
After that, it fades out again. Tuesday the 28th of July is back to ordinary, with a 4ft NE swell but a cross-off wind that’s okay. The energy is down to 118. It’s surfable, but not exciting. Wednesday and Thursday see glassy conditions but the swell is tiny, between 3ft and 3ft, and the energy is very weak (under 100). The wave comment says “surfable waves but very ordinary conditions”, and that’s about the size of it.
The long-range stuff, like the 31st of July, has a little 3ft NE swell with a 10-second period and glassy conditions, which is promising but a long way off. The energy is moderate (188). It’s a maybe, but don’t bank on it.
So, the bottom line: if you’ve got a board and a bit of patience, point your car towards Polihale on the 26th. That’s your shot. The rest is a waiting game.
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.
