The Lowdown
Alright folks, Rusty here. Let's break down the next couple of weeks.
It’s going to be a real quiet stretch, I won’t lie. There’s a long gap of grotty surf and bad wind right through the first weekend and into the start of the week. The 25th, 26th, and 27th of July are all a washout – onshore winds and tiny, weak swell. Don't bother.
Your first real chance to paddle out is on Tuesday the 28th of July. Portreath Harbour Wall (United Kingdom) will have a clean little wave. It’s only 2ft from the WNW, but the period is a solid 9 seconds, so it’ll have some shape. The big win is the wind: Tuesday morning there’s a light offshore from the SE, and by the afternoon it goes dead glassy. The water temp is about what you'd expect for this time of year. The combined energy is weak (84-86), but it’ll be clean and rideable. For a little reef, this could be a fun, uncrowded session if you’re an advanced surfer looking for a few proper turns.
The one that’s promising but further out lands on Friday the 31st of July. The afternoon shows a clean, cross-off breeze with a jump in size to 7ft from the SW, with a 7-second period and combined energy of 407. That’s a moderate punch, but the short period will make it feel a bit bumpy and walled. It’s a marginal call, but the clean wind is the only real highlight.
After that, it’s flat and sloppy again until a big, raw pulse shows up on Wednesday the 5th of August. We’re talking 8ft to 10ft from the W, with a 9-second period and combined energy reading over 1000 – that’s very powerful. But the wind is nasty and cross-onshore, so on a reef like this, it’s going to be a mess. Honestly, with that heavy cross-shore wind and big, lumpy swell, this looks more interesting for kite surfing than a paddle session. Only for the experts, and even then, it’s a gamble.
So, the pick of the bunch is that clean, tiny window on Tuesday the 28th. The rest is a long, quiet grind.
Rusty.
