The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Right off the bat, I’ll be straight with you – it’s a grim start. The forecast is a long, dry stretch with no real surf to get excited about. We’re looking at over a week of tiny, weak, or messy conditions. The first glimmer of anything half-decent doesn’t show up until the morning of Sunday, September 13th, at Whitesand Bay.
For that Sunday morning, we’ve got a small 3 ft swell coming from the SW, with a period of 7 seconds. It’s not going to be the biggest or best shaped wave, but here’s the kicker: the wind is forecast to be light and glassy, from the SSE. That’s a major positive. For a break that faces the wind from the east, that glassy condition is going to make the most of the weak energy (104). It’s the only time in the whole 16-day window that conditions look clean enough to be worth a paddle. The water temperature is sitting at 62°, which is about normal for this time of year, so no need to worry about a cold shock.
After that brief window, the forecast goes back to being poor. The wind swings around, the swell drops off, and by the middle of the following week we’re looking at tiny 1.0 ft to 1 ft waves with onshore and cross-onshore winds. That’s your lot for the second week – nothing to write home about. The only real standout in the entire outlook is that Sunday morning session. It’s not going to be epic, but with the wind dropping out, it’s the only chance to get a clean line in for a while.
Stay patient, lads. It’s a long wait for a small, clean window.
Rusty.
