The Lowdown

G'day, I'm Rusty, and I've got the lowdown on the surf at 13th Ave South Surfside. It's a bit of a quiet stretch ahead, so let's get straight into it.

Right off the bat, the water temp is sitting at 84°, which is notably warmer than average for this time of year—a solid 2° above the norm, so you might not even need a spring suit for the dawn patrols.

The forecast is pretty flat for the first ten days, from Tuesday, August 11th, right through to the end of the following week. There's a string of days with tiny, weak waves and poor surf conditions, so you can basically leave the boards in the car. The combined wave energy is mostly under 50 (weak energy), with swells barely scraping 1 ft to 3 ft and short periods. The wind isn't doing us any favours either, mostly cross-on or onshore during the afternoons, keeping things choppy and messy.

The first real flicker of hope shows up on Saturday, August 22nd, in the morning. It's not a standout, but it's the best of a bad bunch. We've got a glassy, clean surface with a light breeze from the SW, and a small 3 ft swell from the south with a short period of 5 seconds. The combined energy is still only 50 (weak energy), so it's not going to be pumping, but for a beginner spot like this, it's the most surfable it'll be across the whole outlook. The south swell direction is a bit off from the optimum SE direction, but it's clean enough to get a few dribbly rides.

A couple of days later, on Tuesday, August 25th, the morning shows a bump in swell to 3 ft from the east, with a period of 8 seconds and combined energy hitting 116 (moderate wave energy). The wind is cross-shore from the northeast at 16 mph, which will put a bit of a chop on the face. It's still not great, and the conditions are poor, but it's the biggest swell of the run. For a beginner break, this could be a bit too much, and the onshore chop will make it a challenge.

Honestly, this is a flat spell that stretches over a week and a half with no real surf to speak of. The spot is inconsistent, and that's showing here. The only real window is that glassy morning on the 22nd, or perhaps the bigger but messier swell on the 25th. For the rest, it's a write-off. If the wind picks up, the setup might be more interesting for kite surfing than paddle surfing, given the small, choppy waves.

Rusty.
