The Lowdown
Alright, Rusty here. Let’s talk about what’s cookin’ for the next couple of weeks. We’ve got a bit of a slow start, but a couple of days are gonna light up.
First up, the swell that shows on Thursday the 20th is a tough one. Sure, it’s 8ft, but that wind is a messy cross-off at 15 mph, and the wave energy is only moderate at 856. It’s a lot of work for not much. The water is 64°, which is totally normal for this time of year, so no worries there.
Then we hit a huge dry spell. From Friday afternoon until the 28th, it’s all poor conditions. There’s a bump on the 27th, but the wind is onshore and choppy, making it a total mess. That stretch is way more fun for the kite surfers than for us, especially with that 7ft cross-shore chop.
The first real standout is Saturday, August 29th. The morning is the call. Trez Hir is pumping with a solid 8ft from the WNW, and the wind is a fresh offshore at 19 mph. The wave energy is strong at 1556, so it’s got plenty of punch. The period is 9 seconds, so it’s a punchy, short-period wave that’ll jack up on the bank. This is a solid heavy day for the experienced crew, but at 8ft, it’s generally too big for beginners. Crowds are possible, so you’ll wanna be early.
Another one to circle is Monday, September 1st. This is a pure glassy morning, my friend. The wind is dead calm at 3 mph from the NW. We’ve got a 6ft groundswell from the WNW, a 10-second period, and a combined energy of 690. It’s a bit smaller than the 29th, but with that glassy surface, this is the pick for the best, cleanest waves. The lines will be way more fun and easier to get into for the intermediate crew.
After that, the swell drops off. The 2nd and 3rd are small and ordinary, with the 3rd being a total write-off with onshore wind. The last few days are tiny, with 2ft to 2ft waves and offshore wind, but just not enough to bother with.
So, bottom line: August 29th for the size and power if you’re feeling brave. For the cleanest, most enjoyable waves, you’re looking at September 1st with that glassy morning.
Keep your wetsuit zipped and your eyes on the horizon.
Rusty.

Information about the Trez Hir Surf forecast
The above surf forecast table for Trez Hir provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trez Hir can be found by selecting the local surf guide option on the grey menu. Our Trez Hir surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Trez Hir) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
