The Lowdown

Alright, Rusty here again. Let's break down the same outlook in feet and miles per hour.

The first rideable surf doesn't show up until Wednesday afternoon, July 22nd. For the rest of this week and into the next, it’s going to be a quiet stretch with tiny, weak waves and poor conditions. A bit of a dry spell, but these things never last forever.

The real standout is shaping up for Monday morning, August 3rd at Little Austi and Main Beach. We’re looking at a solid 5ft swell from the east, with moderate wave energy (380). The wind is a light westerly at 6 mph, cross-offshore, which means it’ll be glassy and clean. The water temp is around 65°, which is average for the season. This is the one to get excited about.

Before that, Sunday morning, August 2nd is worth a look. The swell picks up to 5ft from the east-southeast, with a light cross-offshore breeze from the west-southwest at 9 mph. The energy is moderate (269), and it’ll be clean. A solid warm-up for that Monday.

The long-range stuff gets a bit choppy. Tuesday afternoon, August 4th, brings a bigger, punchier 5ft swell from the east-northeast, with a strong wave energy (632), but the wind is crossing up, making the conditions only marginal. Worth noting, but not the cleanest.

For the beginners, that 5ft to 5ft swell is getting big. The earlier window on July 22nd, with a 4ft swell (231 energy), is a much safer bet. The wind is a light cross-offshore, so it’ll be clean.

Best bet: Monday morning, August 3rd. The rest of the run is a waiting game.

Rusty.
