The Lowdown
Alright folks, Rusty here. Let’s get into it. The next couple of weeks are looking like a real mixed bag for us, with a solid pulse of energy coming through, but we’ve got to wait for the right windows.
The first real action kicks off on Monday the 20th, but it’s a bit of a write-off with a 5ft SSE swell and a cross-shore wind, leaving things a bit messy.
Tuesday the 21st is where we start to see some hope. The morning session is the standout for the early part of the week. We’ve got a clean 5ft swell from the SSE, with a 16-second period, and a light offshore breeze from the west. The water is sitting at 55°, which is a bit colder than normal for this time of year, so don’t forget the thermals. The combined energy is strong at 1379, and the waves are going to have some real power for an experienced surfer. This is for advanced crew only, as it’s got some push to it.
The swell drops off quickly after that, with Wednesday the 22nd offering a glassy 3ft on the SSE, but it’s small. The end of the week is flat, with a poor run of tiny surf all the way through until Saturday the 25th.
Saturday the 25th afternoon sees a jump back up to 7ft from the SSW, but it’s blown out by a 19 mph cross-offshore wind. It’s clean, but the quality is marginal. Then Sunday the 26th afternoon brings a big 10ft SSW swell, but again, the wind is a problem, making it more of a kite-surfing show than a paddle session.
Now, the real gold is coming in the second week. Monday the 27th and Tuesday the 28th are absolute crackers. On Monday, we have a 6ft ESE groundswell with a 13-second period in the morning, clean with a light offshore. By Monday afternoon, the wind goes glassy, the swell is 6ft from the ESE, and the combined energy is a massive 1473. This is the best on offer for the entire forecast. The break is Wainui Beach - Stockroute, an exposed beach and reef setup, and the swell is coming from the direction it loves (SSE optimum). However, it’s a bit of a beast at over 5ft, so it’s for the advanced crew. Expect crowds, as it’s a spot that can get busy.
Tuesday the 28th morning is also a standout, with a 5ft ESE swell and a clean offshore wind. The energy is still high at 1193. The afternoon gets a bit cross-on, so stick to the morning.
The swell eases through the rest of the week, but Wednesday the 29th and Thursday the 30th still offer clean, glassy conditions with 4ft to 4ft ESE swell. The period stays long, so the waves will have shape.
Friday the 31st is still surfable, though the wind picks up a bit. Then, the second week closes with a massive pulse on Sunday the 2nd of August. A 10ft SSE swell in the morning is marginal, but the afternoon is a monster 16ft from the south with a 12-second period. The combined energy is a ridiculous 9374. This is for experts only, and honestly, the wind is strong and cross-shore, making it lumpy. It’s more of a big-wave spectacle than a clean session.
The forecast then fades again, with a small 3ft SSE groundswell on Tuesday the 4th of August offering a clean, long-period option to wrap things up.
The absolute best bet is Monday the 27th and Tuesday the 28th of July. Get on it.
