The Lowdown
G’day, Rusty here. Look, let’s be straight with each other. For the next week or so, Trez Hir is going to be a flat, frustrating affair. Tiny waves, wrong wind, and just not worth paddling out for. We’re looking at a solid stretch of nothing from now through to the 25th of July. That’s a long gap with no real recommendations. You’ll be tempted to look at the ocean, but it’s a waste of time.
Then things start to get interesting. The real story here is the end of the month and the start of August. The standout window is the 27th and 28th of July. That’s where the magic is.
For the morning of Monday the 27th of July, we’ve got a 6ft swell from the WNW, with a period of 8 seconds. The wind is offshore from the WNW at 9 mph. This is going to be clean, with moderate wave energy (831), and it’s shaping up to be something special. This is the best on offer.
The morning of Tuesday the 28th of July is also a ripper, with a 7ft WNW swell, a period of 9 seconds, and strong wave energy (1264). The wind is offshore from the NW at 12 mph. This is big, powerful, and clean. But heads up – at 7ft, this is pushing into expert territory. Not for the beginners.
The wind stays offshore through the 29th, but the swell starts to drop. The 30th and beyond, it’s back to small and ordinary.
So, if you’ve got a board, you’re waiting for that Monday the 27th. That’s the one.
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.
