The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s headed our way.
Straight up, this is a tough run for Whitsand Bay and Tregantle. The forecast is a long, drawn-out stretch of poor conditions with no real standout sessions. The first surfable day isn’t until Saturday, 10th of September, and even that is only a marginal call. Before that, we’re looking at a solid week-plus of messy, blown-out, or tiny surf.
The water is sitting at 66°F which is much warmer than you’d usually expect for this time of year, so that’s a bit of a novelty if you’re just having a paddle, but for surfing, it’s not helping.
The only day that even gets a whisper of a recommendation is the morning of Saturday, 10th September. We’ve got a 4ft swell coming from the WSW with a period of 8 seconds and a light SSE breeze keeping things cross-shore, producing small crossing wind ripples. The combined swell energy is moderate (228). It’s not going to be clean, but it’s the only window where the conditions aren’t completely trashed. The rest of the 16-day window is a write-off for any kind of decent wave.
Given the setup here is a beach break that’s exposed and often crowded, with a lot of strong cross-onshore winds and lumpy, choppy conditions, if you’re into kite surfing, some of those windy afternoons might look more interesting than paddle surfing. For the rest of us, it’s a waiting game. The good news is, this area tends to shift, so it won’t stay poor forever.
