The Lowdown
Alright, Rusty here. Let’s break down what’s coming down the pipe.
Honestly, it’s a pretty bleak outlook for the next couple weeks. There’s a big gap of flat or poor conditions right from the start. The only real highlight is a full week out, on Tuesday the 18th of August. After that, it’s back to small, weak, and unexciting.
The one session to lock in is Tuesday morning, the 18th of August, at Haumoana River Mouth. We’re looking at a clean 7ft swell from the SE with a 10-second interval, and the wind is blowing offshore from the WSW at 16 mph. That’s going to give you some clean, well-formed waves with a good amount of power. The water temp is 53°, which is a bit colder than average for this time of year, so you’ll want a thick suit. The combined swell energy is strong at 773, so there’s plenty of juice. This spot is for advanced surfers only, and you might see a few others out there, but it should be worth the paddle.
Before that, the rest of the first week is pretty grim. There’s a short window on Thursday morning the 13th with glassy conditions, but it’s only a 2ft swell and really weak. Saturday the 15th brings a bump to 7ft, but the onshore wind and rain ruin it.
After the 18th, it drops off fast. Wednesday the 19th has a clean 3ft wave in the morning, but it’s nothing special. Then it’s a slow slide into tiny 0.7ft dribbles by the 24th and 25th – not worth getting wet for.
So, save your energy for Tuesday the 18th at Haumoana River Mouth. The rest of the run is a bust.
Rusty.
