The Lowdown
Alright, folks, Rusty here. Let's be straight with you. The next couple of weeks are looking pretty bleak for a proper surf, so don't get your hopes up too high. We've got a long stretch of small, weak swell and less-than-ideal conditions, but there are a couple of windows where we might snag a fun one.
The first week is a grind. From Saturday the 15th through to Thursday the 20th, it’s mostly knee-to-waist-high slop. The swell is coming from the WNW but it's weak. The wind is a constant cross-off from the north, which keeps the surface clean but there just isn't any push. Monday afternoon the 17th does show a small pulse of 3ft, but it's not enough to get excited about. We're looking at a lot of paddling for not much return.
Things start to perk up a little on Friday the 21st. The morning looks like the pick of the week: the swell bumps up to 4ft from the WNW with a period of 10 seconds and the energy jumps. It's still not huge, but there's finally some push in it. The offshore wind from the NW is a major plus, so it should be clean and lined up. That's your best bet for the first week, and it’s more about getting out there than scoring anything epic.
After that, it kind of drops off again. Saturday the 22nd and into the following week we're back to small, inconsistent surf with weak energy. The wind swings around a bit more, sometimes cross-shore, which chops things up. There's no real consistency to talk about.
Around Saturday the 29th, the swell direction shifts to the southwest. Late Saturday afternoon, we see 5ft of SW swell with a period of 7 seconds. That short period will make it lumpy, and while it's clean, it's not going to be great. By Sunday the 30th, the swell is up a bit more to 5ft and 5ft from the WSW, but again, the period stays short at 7-8 seconds. These are the biggest waves of the whole 16-day stretch, but the short period means they'll be disorganized. It looks like a better prospect for the experts, and honestly, with that clean but messy texture, it might be more interesting for a kite surfer than a paddle surfer.
So, to sum it up: there’s nothing huge on the horizon. The standout is Friday morning (August 21st) at Trez Hir, with that 4ft WNW swell and offshore wind. Keep your expectations in check, and if you're desperate for a wave, that’s your window. The rest is a waiting game.
Stay salty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Trez Hir may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
