The Lowdown
Alright folks, Rusty here with the full 16-day look for Cozies and Geeries. This is a reef and point set-up that works best with swell from the WSW, and it's fairly consistent once the energy shows up.
The pattern starts with a bang, but it's a short-lived, heavy-hitting window. Wednesday the 26th kicks things off with a massive pulse of groundswell. We're talking a solid 10ft to 12ft of raw west swell, with a very long period of 18 to 19 seconds. The combined energy is a massive 7425, showing just how much power is in the water. The morning is a write-off with heavy rain, but the afternoon turns glassy with a light southwesterly. This is a proper, expert-only session – the size and period means it'll be heaving, but it's going to be a clean, heavy wave. The water temp is about average for the time of year.
Thursday the 27th sees a drop in quality. The swell is still big at 10ft, but a strong southerly wind of 22 mph creates a messy cross-offshore breeze. The energy is still high, but the conditions are marginal. Friday the 28th cleans up a bit with a solid offshore from the southeast at 19 mph, but the swell has dropped to 6ft and the energy is down to 1020. It's small and clean, but not a standout.
There's a lull in the action for a few days. Saturday the 29th has a weak, long-period groundswell in the morning, but the afternoon offers a glimmer with 6ft of swell and a clean offshore breeze. The energy is 1947, so it's building. Sunday the 30th and Monday the 31st are average at best, with cross-shore winds and messy conditions.
The real standout in this outlook is Tuesday, September 1st. The morning session delivers a clean 8ft WSW swell, with a light offshore breeze from the SSE. The energy is over 2000, and the conditions are clean. This is the best quality window for experienced surfers. Wednesday, September 2nd is also a gem, with a completely glassy morning. No wind at all, 7ft of WSW swell, and a clean canvas. The energy is 1379, so it's a step down in size, but the lack of wind makes it a potential classic.
The second week is a bit of a mixed bag, but there are some promising signals. The morning of Thursday, September 3rd is a bit lumpy with a cross-onshore wind, but the swell is consistent. Friday the 4th and Saturday the 5th both offer clean, offshore winds, but the swell is smaller at 6ft to 6ft. The energy is moderate, and it's rideable but not spectacular.
Looking further out, the pattern picks up again. Monday, September 7th has a building swell with clean conditions, and Tuesday, September 8th looks like a real highlight. The afternoon is glassy, with a 8ft WSW groundswell and a period of 17 seconds. The energy is a strong 3568. This is a solid, powerful swell for the experts, and perfect conditions. After that, the energy fades into the end of the period.
So, to sum it up: the absolute best on offer is the glassy, powerful swell on Wednesday afternoon, August 26th, and the clean, manageable conditions on Tuesday, September 1st. The Tuesday, September 8th afternoon session is also looking like a cracker, but it's a bit further out, so keep an eye on it. Be patient through the flat spells, the waiting is worth it here.
Rusty.
