The Lowdown
Alright, let’s get this out there. The water’s sitting at about 80° right now, which is pretty much spot on for this time of year. No crazy warm or cold blips to worry about. And for a place like Polihale, that consistency is part of the charm.
Right now, things are pretty flat out at Polihale. We're looking at a poor start to the week with a cross-off wind screaming at 31 mph on Monday afternoon and only 1ft of swell. That’s a write-off. You're better off doing anything else. We've got a real gap here for a few days. Nothing to ride.
Tuesday morning is a whole different story, but not a good one. We’ve got a big 13ft WSW swell with a 10-second period, but the wind is a fresh cross-shore and it’s lumpy as all get out. The energy is strong, reading 2746, but it's messy. This is expert-only, and even then, it’s a gamble. The afternoon cleans up a bit to 7ft and the energy drops to 637, but it’s still pretty average. A bit more organised, but nothing to write home about.
Wednesday morning drops to 4ft from the NNW, still pretty weak with 193 energy. By the afternoon, we finally get a bit of glass. The wind goes slight, the sea is glassy, and we have 4ft of NW swell with a 10-second period. That’s a small step in the right direction, but it’s still just surfable, nothing special.
Thursday morning is down again, 2ft and weak. The afternoon gets glassy but it’s only 2ft. That’s not surf, that’s just a ripple. Friday’s the same story – tiny waves, glassy but gutless. Saturday and Sunday are still small, ankle to knee high at best. We're in a real flat spell here. A long gap with absolutely nothing to get excited about.
Then, things start to shift. Thursday the 17th is where the magic starts. The morning is a bit iffy, but that afternoon we see a proper pulse. 5ft of NNW swell, 12 seconds, and clean glassy conditions. The energy jumps to 759, which is a solid, moderate push. That’s the first real standout of the whole period. This is the one you want to be out for.
Friday morning the 18th keeps it going. 4ft from the NNW, 12 seconds, calm and glassy with an energy of 491. Good surf, no doubt. The rest of that weekend is rideable but nothing crazy. The swell backs off a bit, the energy drops, but it stays clean.
Then we look further out, and there’s another bright spot. On Sunday the 20th, we get a very good forecast again. 4ft NNW groundswell at 12 seconds, glassy conditions, and a significant energy reading of 579. This is the second true standout. It’s a long way off, so don’t book your flights yet, but it’s promising. The following Monday and Tuesday stay good, with 5ft and 4ft waves and clean conditions, but that Sunday is the pick of the second week.
So, for the near term, it’s a waiting game. That Thursday the 17th afternoon is the one to circle on the calendar. Long-period groundswell like this is best at a point or reef, but Polihale is a sandbar. With 12 seconds, it might be a little straight, but when it’s glassy and 5ft, you take it. The energy is there, and the wind will be right. And for the long range, the 20th looks like another cracker, but we’ll see how it shapes up.
Keep the faith.

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.
