The Lowdown

Alright, let’s talk Dumps (Brandon Bay) in feet and miles per hour.

First week’s a mess. From Monday September 7th through Sunday the 13th morning, the wind is all over the place—onshore, cross-onshore—and the surf is just chopped up and lumpy. You might see some size like 10ft (3.0m) on the 12th with a 14-second period, a big groundswell, but the wind from the S and SSW at 18-19 mph is ruining it. That heavy energy reading of 3,520 tells you there’s power; it’s just not clean paddle surfing—more like kite conditions.

The turn comes on Wednesday the 16th morning. A light cross-offshore wind from the SSE at 6 mph, swell around 6ft (1.8m) from the WNW, 10-second period, and clean lines. Energy is moderate at 615. The afternoon glass-off is even better: west wind at 3 mph, glassy, with a 4ft (1.3m) west swell. Perfect for intermediates. Water temp is about 62°, a touch warmer than average.

Thursday the 17th and Friday the 18th build with clean cross-offshore breezes. Thursday afternoon sees 8ft (2.3m) west swell with a clean moderate breeze. Friday morning jumps to 12ft (3.5m) from the WNW at 12 seconds—that’s expert-only territory, with energy at 3,576. Too big for most, but the long-period groundswell will line up nicely on the reef/point.

The standout is Saturday the 19th, morning. Clean 8ft (2.5m) west swell with 10-second period, fresh cross-offshore wind from the SE at 9 mph. Energy is moderate-strong at 1,373 and it’s called excellent for experienced surfers. Crowds are *sometimes*. That’s the session to aim for.

Into the second week, Monday the 21st morning offers clean 5ft (1.6m) NW swell with a cross-offshore NNE breeze. Tuesday the 22nd morning goes offshore from the east, same 5ft NW swell, glassy. Less size but clean.

Summary: first week is a wash. Best on offer is Saturday the 19th of September morning. Wednesday the 16th is a nice clean warmup. Don’t bother before that unless you like chop.

Rusty.
