The Lowdown

Alright, Rusty here again. Let's break it down for you in feet, Fahrenheit, and miles per hour, mate.

We've got a run of decent to excellent surf lined up, especially for the more experienced amongst you. The first proper swell hits us on Monday, the 14th of September, with a solid, powerful groundswell. The energy levels are high – nearly 2000 units – and that means punchy, well-defined lines. The water temp is about average for this time of year, so nothin' too wild.

Monday morning, the 14th, is a standout. The groyne at City Beach is pumpin' with a 7ft WSW swell, a very long 14-second period, and a light offshore breeze from the east. It's glassy and clean, with excellent conditions for experienced surfers. This is proper groundswell, so expect long waits between sets, but when they come, you'll get some throaty, down-the-line waves. It's a bit of a heavy one at 7ft, so not one for the beginners.

Monday afternoon sees the wind shift to a cross-onshore from the SSW, and it gets a bit choppy. Not the pick of the sessions.

Tuesday morning, the 15th, is another solid call. The swell drops slightly to 7ft, but the offshore wind is back from the east at 12 mph, and the energy is still well over 1500. Clean and powerful again. The wind picks up a bit in the afternoon, but it stays offshore, so the quality remains good for the experienced crew.

The swell fades through Wednesday and Thursday, becoming smaller and cleaner. Wednesday afternoon is particularly glassy with a 4ft swell and no wind – a lovely, small, clean wave if you're on a longboard. Thursday morning is poor with a strong cross-onshore wind, so give it a miss.

Then, later in the week, the whole thing gets blown out. Friday the 18th and Saturday the 19th are a write-off for proper riding. Strong winds up to 28 mph, big choppy messy swell hitting 10ft on Friday. It's more of a kiter's paradise than a surfer's dream. The energy is huge but the quality is zero.

We get through a few more marginal days, but the real second standout hits on Wednesday the 23rd of September. A new, clean 7ft groundswell from the WSW with a solid 14-second period. Offshore wind from the east at 12 mph with moderate energy of 1805 units. It's clean and hollow again. Thursday the 24th holds similar promise, with a 7ft swell and clean east winds at 6 mph. This is another prime window.

The end of the forecast period, around Saturday the 26th and Sunday the 27th, is interesting but comes with a caveat. We've got a very long period swell building, hitting 19 seconds on Saturday afternoon. That's proper, deep ocean groundswell. At 7ft with clean conditions, it's a bonafide standout for experienced surfers on a point break or reef. On a beach break like City Beach groyne, that long period can make it break a bit too straight and dumpy. It's still excellent, but you'll want to be on your game or look for a more defined take-off zone.

So, to sum it up: Monday the 14th morning and Wednesday the 23rd are your best bets for clean, powerful, expert-only waves. The weekend of the 26th-27th has enormous potential, but it's a bit more of a wildcard with that ultra-long period.

Rusty.
