The Lowdown
Alright folks, Rusty here. Let's break down the outlook for Trez Hir in the old measurements. This spot doesn't come alive often, so when it does, you gotta listen up. Water temp is running pretty average for this time of year.
The next couple of days are a mix. Friday the 4th afternoon is where things kick off. We've got a 6ft WNW swell rolling in with a clean 9-second period, and the wind is going offshore from the NW. That's a solid look for Trez Hir, giving us clean, surfable waves with moderate energy (485). For a spot that rarely breaks, you take that. Expect some company in the water.
Saturday the 5th afternoon is the clear standout. The swell jumps to 6ft from the WNW with a 12-second period, packing good power (1034 energy). The wind is offshore from the NW again, promising clean, glassy conditions. This is the best window of the whole outlook. Sunday and Monday drop off fast with poor conditions, so don't miss it.
For the more experienced surfers, circle Monday the 7th morning. The swell hits 7ft from the west with a long 13-second period, creating very strong energy (1487). Winds are offshore from the WNW, giving excellent, clean waves. This is big, powerful stuff. The long period means it'll hold up well here, but at this size, it's for experts only.
After that, the swell hangs around but gets trickier. Tuesday the 8th still has clean 6ft waves with offshore winds, but the energy is weaker. By Thursday the 10th, the wind fouls up and the swell drops to a short 8-second period, making it lumpy – better suited for kite gear than a surfboard. The weekend of the 13th and 14th is a flat spell, with tiny, weak swell.
Further out, there's a hopeful sign on Tuesday the 15th morning with a 7ft WNW swell, but the cross-shore wind makes it only marginal. The 17th of September brings back clean conditions with 5ft west swell, offering one last chance. Bottom line: Saturday the 5th afternoon and Monday the 7th morning are your best bets. Get after it.
Rusty.

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.
