The Lowdown
Hey, Rusty here. Let’s call it like it is: the next 16 days at Trez Hir are mostly a struggle. Water temp’s about 64°F, which is dead normal for this time of year.
First real movement comes Saturday, August 29th. Morning brings 8ft swell from the SW (8-second period) with a clean cross-off wind from the WSW at 25 mph, and the combined energy sits at 614 – that’s moderate. In the afternoon it jumps to 10ft from the WSW, still clean, but energy spikes to 1134 – strong stuff. At that size, it’s expert-only, and the short period means it’s gonna be a bit dumpy. Not for beginners.
Monday, August 31st, is the pick. Morning has 8ft from the west with an 11-second groundswell period, clean cross-off, and massive energy at 1626. Then Monday afternoon sees 8ft from the west, 10-second period, and glassy offshore wind from the WNW – clean, lined-up waves, energy at 1119. That’s the session you wait for. Trez Hir is a “rarely breaks” spot, so when it fires like this, you gotta go. Expect a crowd.
Tuesday, September 1st stays clean, 5ft from the WNW (9-second period) in the morning, energy at 345 – just okay. From September 2nd through 4th, it’s mostly small and poor – a real gap in quality.
Then Saturday, September 5th, offers a nice glassy morning: 5ft from the WNW, 11-second period, glassy wind from the SSW at 3 mph, energy at 484. Smooth and clean, but it’s over a week out, so keep tabs on it.
The rest from September 7th to 11th is mostly poor – small swell, sketchy wind, or onshore junk. Tuesday, September 8th morning shows 5ft from the WNW (10-second period), clean, energy at 472 – but the notes call it “poor surf conditions,” so don’t hold your breath.
Best bet: Monday, August 31st afternoon. Saturday, August 29th is worth a look for the brave. Everything else is a waiting game.
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.
