The Lowdown
Alright, Rusty here, let's break down the surf.
We're looking at a bit of a quiet spell ahead, with only one spot really on the radar for most of the next 16 days. It's going to be a lean run, but there are a couple of bright spots if you're patient.
The first decent chance comes this Friday the 17th at Haumoana River Mouth. It's an exposed river bar setup, which can be a bit fickle, and it's considered an advanced break, so this isn't for the grommets. The swell is a clean 4ft from the ESE, but the real story is the period – a very long 16 seconds. That's proper groundswell energy, and with 596 combined energy (moderate) behind it, there'll be some punch. The catch is that a long-period swell on a river bar can be shifty and walled-up, not always offering the best shape. You'll need to pick your sets carefully. Water temp is sitting at 55°, which is about a degree and a half colder than normal for this time of year, so a good 4/3 is a must. There's an early morning window on Saturday the 18th with a cross-offshore breeze from the W that could tidy things up as the swell drops to 3ft, but the real standout looks set for Monday the 27th of July... hold on, let me check the date – yes, Monday the 27th of July. After a long dry spell with hardly any rideable waves, that Monday afternoon looks mint. The wind is forecast to go glassy, with the swell coming in at 2ft from the SE and a solid 12-second period. The combined energy jumps to 309 (moderate), and the word is "expect good surf conditions". That's a proper window to get some clean, lined-up waves. The swell direction from the ESE matches the optimum for the spot, so it's worth marking that one on the calendar.
The rest of the period is pretty grim, with a gap of about 6 days in the middle where you'd be lucky to find anything worth paddling out for. There's a small spike on Tuesday the 28th of July with 5ft from the SE, but that's a short period of 7 seconds and the wind is from the NNW, creating a cross-shore chop. Not great. Another late entry on Saturday the 1st of August has a 3ft swell from the E with a 15 mph SW wind that's offshore and clean, but the wave energy is low (134) and the period is short (8 seconds), so it'll be a bit weak and wobbly. Overall, it's a waiting game for that Monday afternoon session.
Rusty, signing off.
