The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the menu for the next couple of weeks. Honestly, it’s a pretty grim picture for the most part. We’re looking at Trez Hir, and there’s a massive dry spell right out of the gate. From Friday July 17th all the way through to Monday July 27th, it’s basically a flat, frustrating run of tiny, poor surf. You’ll see a few slivers of swell in the 0.7ft to 1.3ft range, but combined wave energy is laughably low (mostly between 6 and 43), and the commentary is stuck on “poor surf conditions.” The water temperature is sitting at 64.4°, which is about average for the time of year, but that’s the only thing that’s normal here. There’s a couple of clean offshore windows, notably on the 18th and the 24th, but with nothing to ride, it doesn’t matter.
The only real glimmer in this whole outlook comes on Tuesday July 28th. Tuesday morning, the wind goes glassy, dead calm, and we get a sudden pulse of 3.3ft of WNW swell with a period of 8 seconds. The combined energy climbs to 126, which is moderate. It’s not a giant day, but for a spot that’s “rarely breaks,” this is the standout. The 3.3ft from the WNW is right in the zone for the optimum direction, and glassy conditions will make it silky smooth. That’s the window to move on. Tuesday afternoon drops off, and Wednesday July 29th afternoon sees a bigger 3.0ft WNW groundswell with a period of 10 seconds and strong offshore wind (12 mph), pushing energy up to 216. That’s a powerful, clean option for the more experienced, but it’s a bit more of a workhorse day. The glassy Tuesday morning is the pick of the litter.
From there, the end of July and into August 1st fades back into the dust. It’s a tough run for Trez Hir, but that Tuesday morning could be a real, rare treat.

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.

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.
