The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
Honestly, it’s a grim start. We’re looking at a long, dry spell with barely a ripple. The first few days are a write-off – poor conditions, small weak swell, and onshore or cross-shore winds. You’d be better off cleaning the wax off your board than getting wet. This quiet patch runs from now all the way through to the end of July and into the first few days of August.
The first real glimmer of hope shows up on Monday morning, the 3rd of August. Portreath Beach wakes up with a clean, gentle offshore breeze from the SE and a little 4ft swell from the north. The energy is still modest (129), and the period is short, so it’s not going to be a classic, but it’s rideable. The water is a touch warmer than normal for this time of year, sitting around 66°, which is a nice bonus.
But the real standout, and I mean the only one worth getting excited about, is that Sunday and Monday the 9th and 10th of August. We’ve got a proper pulse of energy showing up. On Sunday the 9th, the swell bumps up to 6ft from the SW (moderate energy at 435), but the wind is messy. It gets big on Monday the 10th though – a solid 8ft from the WSW with very strong energy (2957). That’s a lot of water moving. The period is 10 seconds, so it’s a decent groundswell, but it’s going to be powerful. The wind is onshore, so it’s going to be a bumpy, expert-only affair. This is not a beginner wave. At 8ft, it’s pushing into the big stuff, and with that onshore wind, it’s going to be a heavy, challenging paddle.
For the rest of the run, the swell drops off quickly after that Monday peak, and the wind stays on it. The 11th of August still has some size (5ft), but the wind is cross-onshore, so it’ll be choppy and messy.
So, if you’re an experienced surfer and you want to charge, mark your calendar for Monday the 10th of August. It’s the only real size on offer, but it’s not going to be clean. For everyone else, keep an eye on the forecasts – it tends not to stay this poor for long.
Rusty.
