The Lowdown
Alright, Rusty here, lookin’ at the forecast for Piha. We got some big, powerful south-west groundswells on the docket, but the wind’s gonna throw a wrench in things for most of the next two weeks. The water temp is about normal for this time of year, so no need to dig out that extra thick wetsuit just yet.
The first week is a bit of a letdown. That Friday the 4th is a right mess, with 10ft (3.0m) swell and onshore winds at 19 mph. The energy reading is a chunky 3669, but it’s just blown out slop. Saturday the 5th brings 12ft to 13ft (3.5m to 4.0m) swell from the WSW, but 12 mph cross-shore winds and chop make it lumpy and hard work. You’d be battling the conditions, not surfing the wave.
Now, listen close, because Wednesday the 9th is our one true shot. The swell eases off to a clean 6ft (1.9m) from the WSW, still with some good 12-second period groundswell. The kicker is the wind. It goes glassy, with just a whisper from the east at 3mph. The combined energy is a moderate 1171, meaning there’s enough push for a good ride but not a world-beater. That morning window is golden for a few clean lines at this advanced spot.
After that, it all goes sideways. Thursday the 10th is back to slop, and then Friday the 11th... hold onto your board. We’re looking at a massive 21ft (6.5m) swell from the WSW with a staggering 20-second period and a combined energy of 34549. The forecast says it’s predicted to be too big for the break. That kind of long-period energy is gonna be howling, with 31 mph cross-shore winds. It’s for the true extremists only. That oversized swell sticks around through the weekend and into the next week, with 16ft to 15ft (5.0m to 4.5m) swells, but the wind is relentless and the conditions are poor.
Honestly, the whole 16-day run is mostly a waiting game. The standout is clear and simple: Wednesday, September 9th, early morning at Piha-The Bar. The 6ft (1.9m) WSW swell with the glassed-out conditions is the only time we’ll see any real quality. For the rest of it, it’s a rough and rowdy ocean that’s better off watched from the beach.
Rusty.
