The Lowdown
Alright folks, Rusty here. Let's take a look at what we've got coming down the pike for Polihale. It's a pretty quiet stretch ahead, to be honest. This spot is a sandbar setup that sees the most action when the swell comes out of the NW, which is its optimum direction. This 16-day window starts off with a whole lot of nothing, and we have to wait a while before the ocean really wakes up.
Right out of the gate, the first few days are a write-off. There are several days of flat to tiny, messy conditions with very low combined wave energy (reading in the low double digits or zero). The water temp is sitting at 80°F, which is basically right on the money for this time of year with an anomaly of just -0.2°F – nothing unusual there.
Things look like they might start to turn late on Monday the 8th, but don't get too excited. The combined energy jumps up to a moderate 1194 from a WSW swell, pushing wave heights to 8ft. That's a powerful pulse, but it's coming in with rain and fresh cross-off winds from the S. This makes it marginal at best – not the kind of clean session you want to paddle out for unless you're seasoned and don't mind a bit of a wrestle.
The first real standout – and honestly, the only one worth circling on the calendar – is Wednesday the 9th. We get a clean pulse from the WNW around 4ft to 4ft, with a period of 10 seconds. The wind is light and cross-off in the morning, shifting to a perfect offshore from the SSE in the afternoon, which will make for glassy faces. The combined energy is a solid 327 in the morning and 275 in the afternoon, so the ocean has some push behind it. For an advanced spot like this, that's the pick of the forecast. Get on it.
After that, the swell backs down through to the middle of the month. The other potential highlight, but a long way out, is from Wednesday 17th to Friday 18th. The finder shows a NE swell building with combined energy hitting 266 on the Thursday morning, and wave heights around 5ft. The wind is light cross-off from the ENE, so it’s looking clean. It’s not a massive swell, but for a long-range call, it's promising. Remember, though, this is an advanced break and a sandbar, so when it gets over 5ft it starts to push past the beginner comfort zone. Anything over 8ft here is expert-only territory. The rest of the days in that second week are just small, weak pulses of energy, mostly in the low hundreds or less, so don't bank on much else.
Signing off, 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.
