The Lowdown

Alright, grab your wettie, let’s have a look at what Trez Hir is serving up over the next couple of weeks.

The outlook kicks off Monday the 14th, but don’t get too excited. The early part is pretty average. A little 3ft W swell (194 energy) is there on Monday afternoon with light cross-off winds, but it’s nothing to write home about. The water temp is 63° which is pretty normal for this time of year, so no surprises there.

Tuesday the 15th shows some promise. The morning has small 2ft WNW swell but with a clean offshore breeze, it’s rideable. The real turn comes Tuesday afternoon though – the swell jumps to 5ft from the WNW, period goes to 10 seconds, and the energy ramps up to 502. With a clean offshore wind, that’s a solid afternoon session for the average punter.

Wednesday the 16th is where it gets interesting. Morning brings a 7ft WNW swell (1093 energy), but the wind is cross-off, so it’s a bit lumpy. The afternoon though – 8ft WNW, 11-second period, 1368 energy, and a clean offshore wind. That’s proper. This is for experienced surfers only though; over 8ft is expert territory, and this is close. The wave comment says “excellent” and the score is high, so this is a standout.

Thursday the 17th is messy. Morning has a cross-off wind that’s a bit strong, and the 6ft swell (561 energy) looks poor. Afternoon is a bit better with a 6ft WNW swell and offshore wind, but the rain showers and moderate breeze take the shine off.

Friday the 18th is the absolute gem of the run. Morning sees an 8ft WNW groundswell with a very long 14-second period and a massive 3183 energy reading. The wind is a gentle offshore. That is world-class potential for the experienced crew. The wave comment calls it “excellent.” This is the best of the best, but remember – this is a beach break, and that long-period groundswell can make it a bit wonky and straight at times, so it’s not for everyone. Afternoon drops to 8ft but still clean with a cross-off wind and 2191 energy.

After that, the quality drops off. Saturday the 19th has a 6ft WNW swell with a cross-shore wind – not great. Sunday the 20th is marginal, with a cross-on breeze. The following week (21st to 29th) is mostly poor. There’s a small pulse on Thursday the 24th afternoon with 5ft WNW (673 energy) and clean winds, but that’s about it. The last few days of September see tiny, weak swells with energy readings under 100, and fresh cross-shore winds. Not worth paddling out for.

So, to wrap it up: the standout is Wednesday afternoon the 16th and Friday morning the 18th. Friday morning is the big one – that 8ft, 14-second groundswell with gentle offshore wind is the session to aim for. Get on it if you’ve got the skill. After that, the surf fades fast.

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.
