The Lowdown
Alright folks, Rusty here. Let’s get into it.
Right off the bat, we’ve got a window of rough conditions to start. The first week is a bit of a write-off with strong onshore winds and messy, blown-out surf. The real action doesn’t kick in until the tail end of the first week, but there’s a solid run of cleaner waves building from the 12th of September onwards.
The standout window is shaping up to be Saturday the 12th and Sunday the 13th of September. Saturday morning at Dumps (Brandon Bay) is looking really good with a 6 ft swell from the WNW and a 10-second period, and the real kicker is the light offshore wind from the east. That’s clean, lined-up surf. The combined swell energy is moderate (800), and it’ll feel solid and punchy. Saturday afternoon keeps the offshore flow, with a 6 ft swell, glassy conditions, and a gentle offshore breeze – perfect for a long session. Then Sunday the 13th, we’ve got another clean morning with the wind shifting light cross-off, a 5 ft NW swell, and the afternoon goes completely glassy with a 4 ft NW swell. That afternoon session on Sunday is the pick of the bunch – light winds, clean faces, and a 10-second period. The water temp is 63°, which is a touch warmer than normal for this time of year, so comfort is on your side.
Beware the first week though. From the 4th right through to the 11th, it’s largely poor surf conditions with strong winds and choppy seas. The swell is big, hitting 13 ft on the 4th and 8th, but the wind is straight onshore and strong, around 22 to 25 mph. That’s a mess. The combined energy on those days is very high (4961 and 4441), but it’s unfiltered, brutal energy – more for the kites than the paddlers. The 5th of September has a cleaner morning with a 7 ft WNW swell and cross-off winds, but the score is only a 3 out of 10, so it’s a gamble.
If you’re looking further ahead, the 18th and 19th of September offer some promise. The 18th of September, Friday morning, is a big one for experienced surfers: an 12 ft WNW swell with a 11-second period, light offshore wind, and clean conditions. The energy is strong (2574), but this is a big, powerful swell that’s not for the faint-hearted. The 19th of September, Saturday morning, is another glassy gem with a 7 ft WNW swell and zero wind. That’s a great way to finish the run.
So, overall, the first week is a gap of rough, poor surf from the 4th to the 11th. The best bet is the clean, offshore weekend of the 12th and 13th, with the glassy afternoon on the 13th being the true standout. The following week has some bigger, more powerful swells for the experienced crew.
Stay safe out there, and get on it when the wind goes light.
Rusty.
