The Lowdown
Alright, crew, Rusty here. Let’s break down what Polihale is looking like. Water’s about average for the season at 80°F, so no drama there.
The first week and a half is a slow grind. From Sunday the 13th right through Thursday the 18th, we’ve got tiny, weak surf. You’ll see waves from 3ft to 3ft out of the northeast, but the energy is low (combined energy in the low hundreds at best). Winds aren’t bad – some glassy mornings and light cross-off breezes – but the waves just don’t have any punch. It’s a flat spell for the most part, with a lot of days where the swell is basically a non-event.
From Wednesday afternoon the 16th all the way to Thursday the 24th, it’s a barren stretch. Swell heights drop to near zero or just a foot or so from all sorts of directions (WNW, SW), and the energy is mostly below 100. Not worth paddling out for.
Then it flips. On Friday the 25th, a real groundswell arrives. The morning is the clear winner: a clean 3ft swell from the WNW with a very long period of 22 seconds. Combined energy jumps to 732 – strong stuff. That kind of period means proper, powerful waves with long gaps between sets. With light cross-off wind from the ENE, it’ll be clean and lined up. This is the best session of the whole outlook. Only for the experienced.
Saturday the 26th keeps the power going: 5ft from the WNW with a 17-second period in the morning. Energy hits over 1000 (1043). That’s big, serious surf – experts only. Light cross-off winds keep it clean, making for a raw, powerful day.
Sunday the 27th is still solid, dropping to 4ft from the NW, periods still long at 13 seconds. Energy remains high (406-362). Clean with light east winds. Good waves for those who can handle it.
By Monday the 28th, it’s back to small and ordinary, 2ft to 2ft and fading.
Bottom line: it’s a flat, frustrating start, but there’s a late burst of proper, powerful swell from the 25th to the 27th. The Friday the 25th morning is the one to circle on the calendar.
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.
