The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming down the line for Trez Hir.
Honestly, it’s a pretty bleak stretch ahead. We’re looking at a long run of tiny, weak surf with hardly any energy to get excited about. The water temp is sitting around 65°, which is normal for this time of year, so no surprises there. But the swell? Barely a pulse.
The first few days are a write-off. Sunday the 9th through Tuesday the 11th are all flat or near-flat, with swell heights below 2 ft and combined energy barely hitting double digits (10). You’d be better off staying home and waxing your board.
Things start to nudge up a little on Wednesday the 12th. The morning sees a bit of a bump with 3 ft swell from the west, but the wind is onshore and messy. By the afternoon, the wind swings offshore from the NW at 15 km/h and the swell pushes to 3 ft with a period of 9 seconds. The combined energy climbs to 141 (moderate), but the wave quality is still described as ordinary. It’s surfable, but nothing to write home about.
Thursday the 13th morning is the best of a bad bunch. The swell is 4 ft from the west with a period of 11 seconds—that’s a groundswell with some real push. The wind is light and cross-offshore from the WNW at 10 km/h, which should keep things clean. Combined energy hits 287 (moderate), and the forecast actually says “expect good surf conditions.” That’s your standout window. If you’re going to paddle out, make it Thursday morning. The afternoon sees the wind pick up to 20 km/h offshore, still rideable but less clean.
After that, it fades fast. Friday the 14th and Saturday the 15th drop back into the 2 ft to 3 ft range with weak energy (133 down to 43). The wind is mostly cross-offshore, but the swell is just too small and weak.
Then we hit another dead zone. From Sunday the 16th through Tuesday the 18th, it’s back to tiny waves under 2 ft and combined energy in the single digits to low 20s. Not worth looking at.
Wednesday the 19th morning sees a slight uptick—3 ft from the WNW with a short period of 6 seconds and combined energy of 107 (moderate). The wind is light and cross-off from the north, so it’s clean, but that short period means the waves will be weak and crumbly.
Thursday the 20th morning brings the biggest swell of the whole forecast: 4 ft from the WNW at 10 seconds, with combined energy of 322 (moderate). But the wind is cross-off from the NE at 25 km/h, which will chop it up. The forecast calls it marginal. The afternoon is even worse with 35 km/h winds. Not a good call.
The weekend of the 22nd and 23rd is a mess—strong NE winds, chop, and dropping swell. By Monday the 24th, the swell is back to 3 ft from the WNW at 9 seconds, with energy in the 150s, and the wind is offshore or cross-off, so it’s clean but average.
Bottom line: the only real standout is Thursday the 13th morning. That’s your window. The rest is a long, drawn-out wait for nothing special.
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.
