The Lowdown
Alright, surfers, Rusty here with your full 16-day look at Trez Hir. Let's cut straight to it.
First up, the water's sitting at about 64 degrees, which is exactly average for this time of year – nothing weird going on there.
The next few days are a write-off. Tuesday through Thursday have surf in the water, but it's small, weak, and the wind's all wrong. You're looking at chest-high slop at best with cross or cross-onshore breezes messing it up. Not worth paddling out. Friday the 28th sees the swell jump up, but that fresh cross-shore wind will have it looking lumpy and ugly. The energy levels pick up though, hitting 418 (moderate) by Friday afternoon.
Saturday the 29th is still messy. Swell around 6 feet from the southwest, but a moderate cross-shore breeze is putting chop all over it. Not your day. Sunday the 30th is more of the same, with a fresh breeze ruining things.
Then we get a glimmer. Early Monday morning, August 31st, we've got a clean 7-foot swell from the west, period 8 seconds, and a moderate offshore wind from the WNW. The energy is moderate (545). It's still a bit raw, but that offshore breeze will clean it up nicely. It's a decent option if you're keen.
The real standout window opens up Tuesday afternoon, September 1st. The combined swell energy jumps to a strong 1490. The swell bumps to 8 feet from the west, period 9 seconds, with a clean cross-offshore wind. This is proper. Then Wednesday morning, September 2nd, might be the pick of the whole run. We've got 8 feet of west swell, 10-second period, and a light cross-offshore breeze. The energy is strong at 1147, and it's forecast for "very good surf conditions." This is the one to circle. Heads up though – Trez Hir rarely breaks, so it needs all the right pieces to fall into place. When it does, it's worth the wait.
After that, it gets a bit inconsistent. Thursday and Friday the 3rd and 4th drop off in size and energy, but we do get a clean 3-foot wave on Friday morning – small but clean for a cruiser session.
The second week has more promise. Saturday, September 5th starts building again, with 8 feet from the west, period 9 seconds, and clean conditions, though a moderate breeze. By Wednesday, September 9th, we're looking at a solid 7-foot west swell, with a long 11-second period, and a clean cross-offshore breeze. The energy is strong at 1144. Then Wednesday afternoon the swell peaks at a powerful 10 feet from the west, period 11 seconds, and energy at a massive 2302 (very strong). That's expert territory. For a wave of that size and period at a beach break, it might be better suited for the more experienced crew looking for a serious challenge.
So, to put a point on it: your best windows are the morning of Wednesday, September 2nd for a clean, powerful session, and then the morning of Wednesday, September 9th for a bigger, long-period groundswell. The crowds at Trez Hir can show up sometimes, so get in early.
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.
