The Lowdown
Right, folks, Rusty here. Let me tell you straight up: the next couple of weeks are looking pretty grim for a paddle. We've got a real wild stretch of weather and swell, but the conditions are just not playing ball for the most part.
Ersary beach (Barra) is our only spot on the list, and it's a consistent beginner-friendly beach break, so it's a shame the forecast is so messy. The wind is the main villain here. For the first week, from Saturday the 5th to Friday the 11th, it's a total write-off. We're talking near gale-force winds, cross-onshore, onshore, you name it. The swell is massive, hitting 16ft on Tuesday the 8th, with the combined energy of all swells at a whopping 7302 (very strong). But that's just for the kitesurfers, not for us. The water temperature is about average for the time of year, nothing to get excited about.
We finally get a little window of opportunity on the 12th of September, Saturday morning. The swell drops to a more manageable 7ft from the west, with a clean 11-second period. The wind is light and offshore (NNW), which is a major positive. The combined energy is still a moderate 1089, but the wave comment says "marginal surf forecast or questionable tide conditions." It's a glimmer, but not a standout. The surf quality is still a bit off.
After that, it's back to the same story. The wind picks up again, the swell gets messy, and the rest of the week is a washout. There's a moment on Monday the 14th, afternoon, where the swell is 10ft from the WSW, but the wind is a fresh cross-shore, and the forecast says it's "too big for this break." Even though it gets an 11/10 internal score, a 10ft beach break with a 7-second period and lumpy cross-chop is not a good time. It's a mess.
The last few days from the 15th to the 20th are a mix of strong cross-shore winds and large, messy swell. The only hint of anything is on Thursday morning the 17th, with a 8ft, 12-second period swell from the W, but again, the wind is a fresh cross-shore and the conditions are "marginal."
Honestly, this is a tough run. The swell is there, but the wind is relentless. The only real, *slight* possibility is that Saturday morning, the 12th. Keep an eye on the forecast, but don't hold your breath. For the rest of the time, the beach is blown out, the waves are too big and messy, or both. It's a blank run for the area, and it looks like it's gonna stay that way for a while.
Rusty.
