The Lowdown
Alright, mate, let's be real – it's a tough stretch on this coast. Water's a touch warmer than average for this time, sitting around 65°F, but the swell and wind just aren't cooperating.
The first real chance to get wet doesn't come until Saturday, September 5th. Before that, from Wednesday, August 26th all the way through Friday, September 4th, it's a write-off. Onshore winds, messy chop, and tiny, weak swell. There's a pulse on Friday, August 28th that hits 6 ft from the SW, but with a short 7-second period and 19 mph onshore winds, it's just a mess. Then Saturday, August 29th sees 8 ft SW swell but with 28 mph winds – that's kite-surfing stuff, not paddling. The energy is strong (1083), but the quality is zero.
The only true standout in the whole 16 days is the morning of Saturday, September 5th at Whitsand Bay and Tregantle. We get glassy conditions with a light NNW breeze – that's a big win. The swell is 4 ft from the SW with a short 5-second period, so it's not going to be epic, but it's the best we've got. The combined energy is weak (80), but the glassy wind will make it rideable for beginners and intermediates. The break is exposed to the SW, which is exactly where the swell's coming from, and it's inconsistent here, so don't expect a crowded lineup, though crowds are often around.
After that, Sunday, September 6th morning offers a clean 3 ft SW swell with a nice 10-second period and a light cross-off ESE breeze. The energy is moderate (165), and the shape should be better, but it's still small. The wind will be clean, so it's a solid backup.
The rest of the second week is flat. Swell drops to nothing – on September 10th, we're looking at 0.3 ft. So, if you're keen, the morning of September 5th is your window. It's not a classic, but it's the only one worth chasing.
