The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming down the line for this stretch of coast.
To be brutally honest, we’re looking at a pretty grim run for the next 16 days at Whitsand Bay and Tregantle. There are a couple of moments where the swell tries to get its act together, but the wind just won’t play ball, and that keeps things well off the pace for any kind of decent paddle.
Right now, Friday the 28th and moving into the weekend, we’ve got some swell on the cards, but it’s all onshore and messy. On Saturday the 29th, the swell jumps up with a SW swell pushing 7 ft to 10 ft, but with a strong cross-onshore wind at 28 mph, it’s a complete washing machine. Combined wave energy hits a strong 1366, but that’s more for the kites than us paddle guys. It’s the same story on Sunday and into Monday – some decent size in the water, but cross-onshore winds and moderate chop ruin it.
By Tuesday morning the 1st of September, it drops right off to a weak 1 ft, and the energy is down to just 51. Not worth getting wet for.
We then hit a long, flat, and windy spell. The middle of the first week of September is a write-off. The swell pops back up briefly on Monday the 7th with a SSW swell around 6 ft to 8 ft, but again, it’s cross-onshore and choppy. On Tuesday the 8th of September, we see the biggest surf of the period with a 10 ft SW groundswell arriving, and the energy reading is a very strong 1675. But with a fresh cross-onshore wind at 22 mph, it’s just lumpy and raw. That’s expert-only territory with the size, but the wind will make it a battle.
There is one tiny window that stands out as the best on offer. Wednesday morning the 9th of September is the closest we get to a clean-up. The swell is a modest 3 ft from the WSW with a 9-second period and a glassy wind. Combined energy is weak at 140, but that glassy surface is a major positive. It won’t be big, but for a beginner-plus spot like this, it’s the one time the wind isn’t ruining things. Expect it to be inconsistent, and crowds are likely.
Beyond that, it’s back to onshore winds and tiny waves for the rest of the second week. There’s nothing else to get excited about.
So, the standout is that glassy morning on Wednesday the 9th. Keep your expectations low, but you might snag a few clean, soft ones.
Stay patient.
Rusty.
