The Lowdown

Alright, let’s get this one going. The start of this stretch is going to test your patience.

Friday (28 August) is a total dud. Swell is barely there, wind is all over the shop—just a mess. This mood carries through until Saturday (29 August) morning, when we finally see some size. That’s 8 ft from the southwest with a short, jumbled 8-second period. The wind is cross-off, energy is high (703), but it’s raw and unruly. It gets bigger in the afternoon—10 ft—with energy spiking (1726), but it’s still a battle. Beginners, stay on the beach. This is for the experienced only.

Monday (31 August) morning holds at 8 ft from the west with a 10-second period, cross-off wind, and the energy is still high (1375). But Monday afternoon is the one that catches my eye. Drops to 8 ft from the west-northwest, period still at 10 seconds, wind goes light and cross-off. Combined energy drops to a manageable moderate (959), and the wave comment says very good. That’s a solid, clean session.

After that, Tuesday (1 September) and Wednesday (2 September) fade to gutless dribble—knee-high or less. Not worth the wetsuit. Thursday (3 September) is a little better in the afternoon at 4 ft, but still poor.

Then Friday (4 September) arrives with a serious pulse. We’re talking 7 ft from the west-northwest with a very long 13-second period. Energy is strong (1416), and the wind is cross-off. This is pure groundswell—powerful, very long lulls, and that period is going to make it hard at a beach break. It’ll want a point, reef, or river mouth. Trez Hir is fairly exposed and sometimes crowded, so you’ll need to be sharp. It might be a bit marginal on tide, but the quality is there for those who can handle it.

Saturday (5 September) is the standout of the whole run. Swell sits at 6 ft in the morning, then 5 ft in the afternoon, both from the west-northwest with a 12-second period. The wind is almost glassy in the morning—just a whisper from the north-northwest—and then light from the west in the afternoon. Combined energy is moderate (926 and 665). The wave comment says very good and good. Crowds are possible, but it’s worth it. This is the cleanest, most fun surf of the forecast.

It then goes quiet again from Sunday (6 September) through Wednesday (9 September)—waist-high or smaller, with poor quality. A gap of several days with nothing to recommend.

Thursday (10 September) throws up another big one: 8 ft from the west-northwest with a 10-second period and energy at a massive 1961. But the wind is a fresh cross-off at 22 mph, and it’s marked as marginal—raw and choppy. After that, Friday (11 September) and Saturday (12 September) drop off into tiny, frustrated surf, with strong offshore winds that clean it up but make it nearly impossible to paddle into.

Water temp is about 64°, which is average for this time of year. Nothing unusual.

So, my picks: Monday afternoon (31 August) for a clean, manageable session, and Saturday (5 September) for the best overall quality. That Friday (4 September) is the big one, but it’s a test. Good luck.

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.
