The Lowdown
Alright, Rusty here. Let's have a look at what's coming down the pipe for the next couple of weeks.
Right off the bat, we’ve got something to get excited about. Thursday morning the 27th of August, Wainui Beach - Stockroute is looking like a real treat. We’ve got a 3 ft SSE swell rolling in with a very long period of 18 seconds – that’s proper groundswell energy, and the combined energy is sitting at a solid 673 (moderate energy). The wind is a light cross-off from the SW, so the face is going to be clean. This is a beach and reef setup, so with that long period, it might be a bit straight at times on the beach, but the reef should offer up some nice lines. The water is sitting at 55°, which is a bit colder than normal for this time of year, so don't forget the booties. This is the standout of the whole window.
Friday the 28th keeps the fun going. Morning brings a 4 ft SE swell, 14-second period, and a light cross-off from the north. The energy drops a touch to 595 (moderate), but it’s still clean and very surfable. The afternoon drops off a bit in size and quality, but the morning is a solid session.
The weekend is a bit of a letdown. Saturday and Sunday are small, with the swell dropping to 2 ft and then 2 ft. The energy is weak (176 and 77). Sunday morning does have a clean, offshore wind, but there just isn't enough push for anything exciting. It's a couple of days of small, ordinary surf.
Now, hold on to your board, because Monday the 31st of August is a big one. The morning sees an 8 ft SSW swell, 10-second period, with a clean offshore wind from the NW. The combined energy is pumping at 1788 (strong energy). This is a serious swell, but it's big enough that it's only for experienced surfers. The period is a bit shorter, so it might be a bit of a lumpy, powerful beast. The morning is the call here, as the afternoon gets a bit cross. Then Tuesday the 1st of September morning is even bigger, with an 8 ft SSW swell and 12-second period, hitting 2393 (strong energy) on the energy scale, but the wind is cross-on, making it messy. The real gem on Tuesday is the afternoon - it goes glassy as the wind drops to an easterly 3 mph, and the swell drops to a still-chunky 6 ft from the SSE. That's a magic window.
Wednesday the 2nd of September continues the run with a clean 4 ft SSE swell and a solid offshore breeze from the NW. The energy is a moderate 520. It’s clean, it’s consistent, and it’s a great day for a paddle.
After that, it’s a slow fade. The rest of the first week of September and into the second week is small. The swell drops to under 3 ft, and while the winds are often offshore, there just isn't the energy. There’s a bit of a pulse on the 9th of September, with a 3 ft SSE swell and a clean morning, but it’s nothing to write home about. The last few days of the forecast are almost flat, with tiny waves and poor conditions.
Overall, the week is a classic Spring pattern. A couple of absolute crackers, a few days of ordinary, and then a long, flat spell. The best bet is Thursday morning the 27th of August for the quality, or Monday morning the 31st of August for the size and power, but that one is for the experts only.
Rusty.
