The Lowdown
Alright, this is Rusty comin' at ya from the North Shore. Listen up, 'cause we've got a solid run of swell heading our way, but you gotta pick your moments.
The next few days are all about the big groundswell, but it's gonna take a little patience. The action kicks off proper on the morning of Tuesday, September 1st. Off The Wall is looking at a solid 10ft of SW groundswell with a 13-second period, and the wind is dead glass – flat calm. That's a recipe for perfection, but with that much power, this is strictly for the experienced crew. The combined energy is a massive 2639 – that's a lot of juice in the water. The water temp is sitting at 56°, which is a whopping 4° colder than usual for this time of year, so you're gonna want a thick wetsuit and maybe some booties for that first session.
Wednesday the 2nd keeps the size at 10ft from the SW with that same long 13-second period, and the wind stays light and cross-offshore. It's still a heavy, powerful wave for experts only. The energy is still pumping, around 3299 in the morning. This is the standout block of the whole forecast.
We get a bit of a break on Thursday the 3rd. The swell drops to 6ft, but the wind cranks up from the south, and by the afternoon a near gale from the SSE makes it a real battle to even get out. It's not worth the fight.
The weekend of the 5th and 6th of September sees the swell direction shift around to the SSE, with size still holding at 10ft. The wind is offshore, but it's strong – 25 mph gusts. The waves will be clean, but paddling into them will be a workout. The period drops to 8 seconds on Saturday, so it's a shorter, steeper, harder-to-paddle-into wave.
Now, look ahead to the second week. Monday the 7th of September offers a much more manageable 4ft SSW swell with a nice 12-second period. The wind is light, and the energy is moderate at 709. That's a sweet day for a wider range of surfers.
The swell fades out towards the 8th and 9th, with small, clean waves in the 2ft to 3ft range. Not a lot of push, but if you're on a longboard and the tide is right, you could have some fun on the glassy mornings.
We get a nice little pulse back on the 12th of September (Saturday) – a 6ft WSW swell with a 12-second period and a light offshore wind. The energy is 846, and it's looking clean. That's a solid, fun-sized wave.
The run ends messy on the 13th and 14th of September with onshore northerly winds and poor conditions. The swell is too big and the wind is wrong. There's a last chance of decent surf on the morning of Tuesday the 15th of September: 6ft of SSW swell with glassy conditions. That's a nice little window to close out the forecast.
So, for the best of the best, you're looking at Tuesday morning, September 1st, and Wednesday, September 2nd, at Off The Wall. That's the big, clean, powerful groundswell, but it's for experts only. For the rest of us, the morning of Monday the 7th and Saturday the 12th are the ones to circle.
Rusty.
