The Lowdown
Alright, let’s talk this out in feet and miles per hour.
This is Rusty, and I’m looking at what’s in store for Trez Hir over the next 16 days. It starts off a little scratchy, but there are some gems if you’re patient.
Tuesday morning, September 1st, the water temp is a comfortable 17°, right around average for the year. You’ve got clean, glassy conditions with a 4ft swell out of the WNW, period around 9 seconds and moderate energy. It’s a good start. By the afternoon, the swell drops to about 3ft, wind goes cross-off from the WSW. It’s surfable, but nothing to write home about.
Wednesday the 2nd and Thursday the 3rd are a wash. Onshore wind, messy conditions. Don’t bother.
Friday the 4th morning is still a bit lumpy, but the afternoon cleans right up. Offshore wind from the NW at 12 mph, swell hits 5ft from the WNW, energy strong. That’s a solid afternoon session.
Saturday the 5th has some size—around 5ft in the morning—but the wind is cross-on from the ENE. The period stretches to 11 seconds, energy is heavy, but the wind kills it for paddle surfing. If you’re into kite surfing, this might be your window. The afternoon is marginal.
Sunday the 6th is small and onshore. Skip it.
Now Monday the 7th is the real standout. Morning starts clear, light cross-off wind from the NNW, 4ft swell but with a 12-second groundswell period. Clean waves. The afternoon is even better: offshore wind from the NW at 12 mph, 4ft swell at 11 seconds, energy pumping. Trez Hir will be clean, lined up, and well worth the paddle.
Tuesday the 8th is another cracker. Morning has a slight offshore from the WNW, swell around 5ft. The afternoon picks up to 6ft with a cross-off wind from the W. Good surf both sessions.
Wednesday the 9th is a no-go. Strong cross-on wind at 19 mph, swell hits 7ft, energy is huge, but it’s blown out and lumpy.
The rest of the first week is small or marginal at best.
Into the second week, it’s patchy. Saturday the 12th morning has a 6ft swell from the WNW, but the wind is cross-off and the conditions are just okay. Sunday through Tuesday is poor, with onshore winds and small surf. The last decent session comes on Wednesday the 16th afternoon: glassy conditions, a clean 3ft swell from the WSW with an 11-second period, and good energy. It’s small but clean.
The best days are Monday the 7th and Tuesday the 8th. Offshore winds, real groundswell, and clean lines. That’s where you want to be.
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.
