Topaz Street Surf Forecast and Surf Report

G’day, Rusty here. Let’s talk about what’s coming up at Topaz Street. This is a beach and jetty setup that’s exposed to the west, which matters because our best swell windows are from the SSW and SW. The guidance tells me it’s a fairly consistent spot and beginner-friendly, so good news for anyone just getting into it. Water temp is sitting at 72°, which is much warmer than normal for September, so you can leave the thick rubber at home.

We’ve got a quiet start. Right now, there’s nothing worth paddling out for. That first real chance comes Saturday afternoon, September 5th, with a small SSW swell of 3ft at a very long 16 seconds, but the wind is onshore from the west at 9 mph, so it’s messy. Combined swell energy is moderate at 567. I’d give that a miss.

Sunday the 6th is where things get interesting. The morning shows 3ft of SSW groundswell at 15 seconds, with a light cross-offshore breeze from the NE at only 3 mph. That’s clean. Then Sunday afternoon? Glass. Absolutely glass. The wind drops to zero from the NNE, the swell lifts to 4ft from the south at 14 seconds, and combined energy sits at 524. This is the standout window for the whole outlook. If you only surf one session, make it Sunday afternoon—clean, glassy, manageable size, and the swell direction is working well with the break. Crowds are possible, so get in early.

Monday morning the 7th sees 3ft from the SSW at 14 seconds, but the wind swings back onshore from the west at 6 mph. It’s marginal. Afternoon gets worse with 12 mph onshores. Tuesday is similar with onshore winds and dropping energy—322 on Tuesday morning, 327 in the arvo. Not worth it.

Wednesday morning September 9th is a gem though. Only 1ft of swell, but it’s a very long 19-second SW groundswell, and the wind is glassy from the WSW at 3 mph. That’s butter. Energy is low at 243, but for a longboard or a funboard in the glass, it’ll be clean little runners. The afternoon gets ruined by 12 mph onshores again.

Thursday and Friday, September 10th and 11th, bring back that SW groundswell at 16 to 17 seconds, with waves around 2 to 3ft. Friday morning has the best wind of that stretch—cross-offshore from the SSE at 9 mph—so expect clean little lines. Both Friday sessions are worth a look if you missed Sunday.

From Saturday September 12th onward, things drop off. Swell heights slip to 2ft, wind turns cross-on or onshore, and the energy falls below 200. There’s a couple of days of 7-second windswell from the west mid-month (13th to 14th), but with onshore winds and short period, it’s sloppy. The long period SW groundswell tries to poke through again on the 18th and 19th, but onshore wind messes it up. The only flicker of hope is Saturday morning September 19th, with 5ft of W windswell at just 7 seconds and onshore wind—that’s not surfable, that’s a kite day if anything.

All in, Sunday afternoon September 6th is your best bet by a long shot. The combination of glassy wind, solid 4ft south swell, and good energy makes it the pick. Friday morning the 11th is a solid backup if you missed it.

Rusty.
