The Lowdown

G’day, this is Rusty. Alright, let’s be straight with it—looking at Polihale over the next couple of weeks, we’ve got a pretty flat and quiet run ahead. The first week especially is a write-off for any kind of decent paddle surfing. This exposed sandbar setup needs a solid pulse of NW swell and clean winds to fire, and for days on end, we’re just not seeing it. There’s a long gap with no proper recommendations right through the middle of the period, so don’t hold your breath.

The first sniff of anything worth mentioning comes on Wednesday the 19th in the afternoon. We get a tiny 2 ft swell from the NE with a short, junky 7-second period. Combined wave energy is weak at 73, and the water’s around 81°F with basically no temperature anomaly—average for this time of year. Winds go glassy though, which is a nice look, but the waves themselves are ordinary. Not enough push for a proper session.

Things stay small and mediocre through to the end of the week. Friday the 21st afternoon shows a little more hope with some swell building to 3 ft from the NE, period still short at 7 seconds, energy at 79, and again glassy winds. It’s surfable, but very ordinary.

Now, the one standout in this entire outlook lands on Monday the 24th. Morning brings a 3 ft swell from the WNW with a period bumping up to 11 seconds—a proper groundswell pulse. Combined energy hits 204, which is moderate. The wind is glassy, making for clean conditions. That’s the best on offer over the whole 16 days. For a sandbar like Polihale, long-period WNW groundswell can sometimes run straight, but with these small heights, it should offer tidy, rideable lines. Still, the swell direction is NW, which is the optimum for this spot, so it lines up nicely. Expect crowds sometimes, as it’s fairly consistent and the locals will be out for this one.

After that, Tuesday the 25th is messy with cross-shore winds and dropping energy. Then Wednesday the 26th afternoon shows another pulse: 3 ft from the NNW, 11-second period, and energy up to 250—moderate and punchy. Winds are clean, cross-off from the ENE at 9 mph. This is a solid secondary window. Might be worth a look if you missed Monday.

Beyond that, from Friday the 28th onward, we’re back to weak ankle-biters: 2 ft from the N at 10 seconds, energy dropping into the double digits. Winds stay light and mostly clean, but the swell just isn’t there. The last few days of August and into the 31st are more of the same—small, sleepy, and not going to get your heart racing.

If you’re chasing clean lines and a bit of punch, aim for Monday the 24th morning. The 26th afternoon is the backup. Otherwise, it’s a long flat spell in between. For now, I’d say keep an eye on the forecasts, because this kind of quiet run can turn around quick.

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.
