The Lowdown

Alright folks, Rusty here. Gotta be straight with you – looking at the 16-day window for Trez Hir, it's a real mixed bag, and mostly a quiet one. There’s a bit of a wait on our hands.

Right now, we've got a bit of a gap to start. The first sign of life comes in on Thursday, August 13th. For Thursday morning, Trez Hir is showing a clean 4ft swell from the W, with a period of 11 seconds and a light NW offshore breeze. The water temp is sitting at 65°, which is pretty much normal for this time of year. The combined swell energy is moderate at 277, so there's some push there. Honestly, this Thursday morning session is the standout of the entire forecast – it's the only real clean, rideable window we get early on. It'll be small but fun, a real glassy morning for a sneaky session.

After that Thursday morning high point, things go downhill fast. Thursday afternoon, the wind picks up, and from Friday the 14th all the way through to Saturday, August 22nd, it's just a long stretch of tiny, weak, or messy conditions. There are days with cross-offshore winds, but the swell is just too small and weak – mostly under 3ft with combined energy in the double digits or low triple digits. That's barely enough to get your fins wet. For over a week, it's pretty much a flat spell. Don't bother checking the cam.

Now, hold on, because the pattern looks like it might try to change towards the end of the window. On Sunday, August 23rd, we see a spike in size – 7ft to 8ft from the WNW, with energy jumping way up to 866. That's a lot of water moving, but the winds are messy, coming cross or cross-on, and conditions are labelled as marginal. Monday the 24th of August morning looks a little cleaner with a cross-offshore wind and a 7ft WNW swell (combined energy of 752), but there's a risk of thunderstorms in the forecast. That 7ft is getting into the size range where it's not for beginners, and with that kind of energy, it could be a beast.

Further out, Friday, August 28th sees another pulse – 6ft from the WNW with a 10-second period and energy at 855, but it's blowing a strong breeze from the NNE. So, while there might be size, the quality is a real question mark. Those later pulses are promising but very uncertain this far out.

For a break that rarely breaks, this blank run is actually pretty normal for Trez Hir. You have to be patient here. The one clear call, the best on offer, is that Thursday, August 13th morning session – it's your only shot at clean, surfable waves in the near term.

Rusty, signing off.

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.
