The Lowdown
Right then, let’s have a look at what Trez Hir has got cooking for us over the next couple of weeks.
Alright, so we’re starting off a bit rough. The next few days are looking pretty average, to be honest. You’ve got some solid-looking swell numbers coming through, like Saturday morning with 8ft from the WSW, but it’s getting hammered by a strong cross-off wind at 28 mph. The water temp is sitting at 64°, which is pretty much normal for the time of year, so no surprises there. The energy in the water is moderate (910), but the wind is just ruining it. It’s a bit of a write-off until we get to Monday.
Now, Monday the 31st of August is where things start to look proper. Monday morning we’ve got a clean 8ft swell rolling in from the west, with a 10-second period. The wind has swung around to a light offshore from the NW at 12 mph, and the energy has jumped up to 1316 – that’s proper moderate to strong stuff. This is the standout window. The waves are going to be well-shaped, and that offshore breeze will keep things clean as a whistle. If you’ve got a free morning, that’s your call. Monday afternoon keeps the same quality with a 8ft west swell and even lighter offshore winds from the WNW. Honestly, Monday is the pick of the first week.
After that, things drop off again. Tuesday and Wednesday are small and messy, with lumpy cross-shore winds. Not worth paddling out for unless you’re desperate for a float.
Then, there’s a gap of a few quiet days until we hit Saturday the 5th of September. Saturday morning is a real dark horse. We’ve got a 6ft WNW swell, but the wind goes totally glassy from the south at just 3 mph. The energy is a solid 686, and the conditions are glassy. It’s a smaller wave, but it will be perfect for a longboard or a funboard. This is the second standout – a real gem for a relaxed, clean session.
The following week is mostly a dud. There’s a bit of swell around the 11th and 12th of September, but the wind is howling again. By the 13th of September we get a whisper of a very long-period groundswell at 16 seconds coming in from the west, but it’s only 2ft. The energy is a bit deceptive (410) because of that long period. That kind of swell can work nicely at a point, but Trez Hir is a beachie, so it might just close out or be too straight. It’s more of a curiosity than a solid bet.
So, the two standouts to mark on the calendar: Monday the 31st of August for a proper, punchy west swell with clean offshore winds, and Saturday the 5th of September for a glassy, smaller session when you just want the ocean to yourself.

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.
