The Lowdown
Alright, Rusty here. Let’s talk about what’s going on with the surf around here.
The 16-day window kicks off, but honestly, it’s a grim start. We’ve got a real rough patch ahead, with no surf worth paddling out for until around Thursday the 10th of September, and even then it’s marginal. The weather is just not playing ball, with strong winds and messy conditions dominating the forecast. There’s a big gap of nothing good at the beginning, which is a real shame.
The only spot on the radar is Ersary beach (Barra). It’s a consistent, beginner-friendly beach break, exposed to the NW. The water temperature is about average for the time of year, nothing unusual there.
The first real chance of a wave comes on Thursday, September 10th, in the afternoon. We’re looking at a 7ft swell from the WSW, with a period of 9 seconds, and the combined energy hits 1221 (moderate wave energy). The wind is cross-shore, but it’s a fresh breeze, so it’s going to be lumpy and choppy. It’s a marginal call at best, honestly. The swell is pushing 7ft, which is getting a bit big for the beginners this break usually suits, and the wind won’t do it any favours.
After that, the forecast is a real mess. The rest of the period is plagued by strong, onshore, and cross-offshore winds, with near gale-force gusts. Swell sizes range from 3ft to 15ft, but the wind just ruins everything. For example, Monday the 7th has a 12ft SW swell, but it’s cross-shore and messy. The 15ft swell on the 7th afternoon is a joke. The 13ft west swell on Tuesday the 8th is blown out by a near gale. It’s all just one big, windy, blown-out mess.
There is a lot of energy in the water, with combined energy readings regularly hitting three and four-digit figures (2893, 4981, 3713), but it’s all for nothing. The wind is just too strong. Given the beach-break setup and the size of the swell, this would be a much more interesting prospect for the kite surfers than for anyone on a paddle board.
For the second week, from the 14th onward, it’s more of the same story. Strong winds, cross-onshore, and messy conditions. The swell is there, but it’s not rideable. Keep your gear in the shed and wait for the next proper window.
Rusty.
