The Lowdown
Alright folks, Rusty here. Let's have a look at the surf for Wainui Beach – Stockroute.
First off, this stretch is an exposed beach and reef setup, and when the right swell lines up, it can be a beauty. The water temp is running pretty average for this time of year, nothing too weird going on there.
The opening action on Sunday the 9th is a solid start. We've got a clean 3.3ft swell from the SSE, with that light cross-off breeze from the NNW making things tidy. The energy is moderate (346) and it's packing an 11-second period, which is decent groundswell – gives you some push. This is your go-to for the early part of the week. Sunday afternoon and Monday are a bit average, with the wind shifting around and the swell dropping off. Monday morning stays clean with light offshore winds, but it’s pretty small at 2ft.
Now, the real standout pops up on Tuesday the 11th. Tuesday morning is the pick of the first week. There's a jump in size to 6.2ft from the SSW, and the combined energy is cranking at a solid 765. It's a shorter period at 8 seconds, so it's more of a wind-swell pulse, but with that NW cross-off breeze, it will be clean and powerful. This is the session for the advanced crew – anything over 5ft starts to get serious, and this is solidly in that zone.
From there we get a mix of conditions. Wednesday the 12th morning looks good again with a clean 4.3ft from the SE and offshore winds, another clean window. The rest of the week is a bit messy with onshore winds and lumpy conditions, especially Thursday and Friday. Friday the 14th sees a jump to 6.6ft from the NE, but the wind is cross-shore and it’s a bit of a gamble. Saturday the 15th morning has some promise with a clean 4.9ft from the E and offshore winds – a solid option.
The second week gets a bit wild. From Sunday the 16th onwards, the swell builds considerably, but the wind goes nuts, mostly strong cross-shore breezes. We’re looking at 7.2ft, 8.2ft, and even 11.5ft on Wednesday the 19th, but the wind is tearing it apart. The combined energy gets massive, up to 3298, but for a standard paddle, it's going to be a battle. This setup looks more interesting for kite surfing than paddle surfing through the middle of that week. Things start to settle a bit towards the end of the week on the 20th, but it's still messy.
The tail end of the forecast period has a glimmer of hope. Sunday the 23rd morning is a clean option with a 4.6ft from the E and a cross-off breeze. Then, the absolute last call, Monday the 24th morning, looks like a good one. Clean 5.9ft from the E, with a solid offshore from the WNW. This is one to watch for the future, but it's a long way out.
Stay safe out there.
