The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
The outlook is a bit of a heartbreaker, to be honest. We’re looking at a long stretch of just… nothing much. The data kicks off on Monday, 3rd August, and for the first week and a half, it’s pretty grim. There’s a couple of windows where the conditions are "clean" but the swell is so tiny it’s barely a ripple. The first real chance of a wave doesn’t show up until Wednesday, 12th August.
The best of a bad bunch, and the only spot worth highlighting, is Portreath Harbour Wall. It’s a reef setup, tricky and for advanced surfers only, and it’s fairly consistent, though crowds are likely here. The optimum swell direction is from the NW, and the water temp is about average for the time of year.
On Wednesday, 12th August, the morning brings a clean, offshore breeze from the ESE at 22 mph. There’s a 5 ft swell from the north, with a short period of 6 seconds and a combined energy of 212 (moderate). It’s a clean, offshore setup, but the swell is a bit short-period and the size is starting to push into the range that’s more for the experienced crew. That afternoon, the wind eases to a moderate offshore from the SE at 16 mph, with a 5 ft north swell, period still at 6 seconds, and energy of 151. It’s "surfable but very ordinary," which is the best we get.
Other than that, it’s a long, flat, or blown-out run. From Monday, 3rd August all the way through to Tuesday, 11th August, and again after Thursday, 13th August, the scores are all zeros. The swell is either too small, too short-period, or the wind is onshore or cross-shore and making a mess. There’s a gap of about 8 days with no real surf on offer to start.
So, if you’re an advanced surfer and you’re desperate, you’ve got a small window on the morning of the 12th. Otherwise, this is a blank run for the area. The forecasts can change, but right now, it’s looking pretty quiet.
Rusty.
