The Lowdown

Alright folks, Rusty here. Let’s break down what’s on the table for the next couple of weeks.

We’re looking at a real mixed bag, with a nice pulse of solid swell kicking off the first week but then it fades into a long, quiet spell. The standout is definitely Monday the 31st of August, which is the clear highlight of the whole forecast period.

Starting off, we’ve got a bit of a fizzer. Sunday the 30th of August is a write-off – messy, stormy, and a strong cross-breeze. The combined energy of all swells is only 482, so it’s moderate at best, but the wind and wave quality are just poor. Water temp is sitting at 64°, which is about average for this time of year – nothing unusual there.

Then we get the goods. Monday the 31st of August is the one to circle. The morning brings a solid 10ft groundswell from the west, with a period of 10 seconds and a combined energy of 1545 – that’s strong energy. The wind is offshore from the WNW, which means clean, well-shaped waves. This is excellent surf, but it’s 10ft, so this is strictly for experienced surfers only. That afternoon, the swell drops a touch to 8ft, still clean and offshore, with energy at 1138. Still a strong session for those who know what they’re doing.

Tuesday the 1st of September, we settle down. Morning is small, 4ft, with a light cross-onshore breeze. The afternoon is smaller at 3ft, clean but nothing special. The energy drops to 295 and 173 – weak to moderate.

From Wednesday the 2nd through to Thursday the 3rd of September, it’s pretty flat and ordinary. Swell stays under 5ft, winds are mostly cross or cross-off, and the energy is weak – down around 77 to 273. Not worth paddling out for.

Friday the 4th of September, a little bump comes through. Swell builds to 6ft from the WNW, with a longer period of 11 seconds, and the energy jumps to 958 and 1121 – moderate to strong. The wind is cross-off, so it’s clean. But the forecast notes it’s marginal – maybe tricky tides or conditions. Worth a look if you’re keen, but keep expectations in check.

Saturday the 5th of September is a decent option. Morning brings 6ft WNW swell, 11-second period, energy at 780, and a light cross-off breeze. The afternoon is a bit smaller at 6ft, but the wind swings offshore from the NNW, keeping it clean. Both sessions are rated as very good surf conditions. This is a solid day for intermediate to experienced surfers.

After that, it’s a long, slow fade. From Sunday the 6th of September right through to Monday the 14th of September, the swell drops and stays small. Most days are under 3ft, with weak energy (sometimes below 100), and the winds are often cross-on or variable. There’s a brief moment on Wednesday the 9th of September morning with glassy conditions and 3ft, but it’s tiny. Then on the 11th of September, we see a small bump to 5ft, but the energy is moderate and the conditions are marginal. Honestly, after the first week, it’s a pretty quiet run. The breaks are rarely consistent here, so that blank stretch isn’t too surprising.

Now, talking about Trez Hir itself – it’s a spot that rarely breaks, so when it does, it’s a bit of an event. It’s fairly exposed to the swell, and the optimum direction is from the SSW. The main standout on Monday the 31st of August comes from the west, which is a bit off its perfect angle, but the size and clean offshore wind more than make up for it.

So, to wrap it up: if you’re an experienced surfer, Monday the 31st of August is the absolute best on offer. Saturday the 5th of September is also a good one. After that, it’s pretty quiet. The breaks are inconsistent, and that’s just the way it goes here sometimes.

Rusty out.

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.
