The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’re looking at a pretty quiet stretch for Polihale. The first real surfable waves don't show up until mid-August, so there’s a long gap of flat or near-flat conditions from the start of the forecast right through the first week. Nothing worth paddling out for until Friday the 14th.
The first hint of something rideable comes on the morning of Friday the 14th. We’ve got a small 2ft swell rolling in from the west with a period of 12 seconds and wave energy sitting at 100 (moderate). The wind is light and cross-off, keeping things clean. It’s pretty ordinary though – small, but that’s the start of a little pulse. The afternoon picks up a touch to 2ft from the west, period drops to 11 seconds, energy down to 91, still clean. You can get a few fun little ones, but don’t expect anything special.
Saturday the 15th is a bit mushy, still 1ft to 2ft from the west-northwest and west, but the wind gets up to 9-12 mph in the afternoon, so it’s not as clean as Friday. The energy is moderate (95-103), but the quality is poor. Not a day to get excited about.
Into the second week, Sunday the 16th morning sees a slight bump to 2ft from the west, period 14 seconds, energy 138 (moderate). That’s a bit more energy, but the wind is up at 9-12 mph, so it’s messy. Monday the 17th morning is similar – 2ft from the west, 12 seconds, energy 110, with lighter 6 mph wind making it look cleaner. That’s probably the best on offer in the whole run: small, clean, but consistent enough for a longboard or a fun mid-length. The swell direction is west, which matches the guidance optimum, and the cross-off wind keeps the surface nice.
For the rest of the run, Tuesday the 18th through Thursday the 20th, the swell stays small, 1ft to 2ft, period dropping to 11-12 seconds, and energy fades fast. Thursday the 20th morning is glassy with 1ft, but it’s tiny.
Water temperature is 81°F, which is about average for this time of year – nothing unusual there.
The real standout? Monday the 17th morning. It’s not big, but it’s the cleanest, most consistent window with a west swell, light wind, and moderate energy. It’s a small, clean day for a quiet paddle. Not for beginners, but it’s not a big day either.
So, all in all, a flat start, then a small pulse mid-month, with Monday the 17th morning being the pick of the bunch. 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.
