The Lowdown

Alright folks, Rusty here. Let's break down what we've got on the cards for Trez Hir over the next couple of weeks. It’s a bit of a mixed bag with some real gems hidden in there, so listen up.

Right now, the water temp is sitting at a pretty average 63° for the time of year, so nothing unusual there. The week kicks off with a bit of a slow start, but we've got a Friday morning session that's worth a paddle out. We're looking at a clean 5ft swell from the west, with a light cross-offshore breeze keeping things tidy. The wave energy is moderate at 408, so there's enough push to have some fun.

Saturday starts a bit messy with a small, onshore swell, but hang in there because Sunday the 13th is where it picks up. Sunday morning we’ve got a solid 6ft swell from the WNW with an 11-second period, and that cross-offshore wind is going to shape up some nice lines. The energy jumps right up to 740 (moderate), and it's looking very good. This is the standout for the first half of the week – get out there.

Monday and Tuesday are not worth bothering with; the swell drops off or gets blown out by strong offshore winds that will make it tricky even if it's clean. Then Wednesday the 16th morning looks really promising again. We've got a 8ft WNW swell with a 10-second period and a moderate offshore wind from the NNW. That's a powerful combo with energy at 943, and it's forecast to be very good. Keep in mind, at 8ft, this is pushing into expert territory for some. By Wednesday afternoon, the wind picks up and the forecast gets a bit questionable.

Looking into the second week, things get more interesting but also more uncertain. Thursday the 18th afternoon looks solid with a clean 6ft WNW swell and a 12-second period. The energy is strong at 1013, and the wind is sweet. Then we get to the big one. Sunday the 20th morning is looking mint – a 10ft WNW groundswell with a very long 15-second period and clean light winds. The energy is massive at 3319. This is pure, powerful groundswell. At this size, it's only for experienced surfers. That long period will mean long lulls between sets, but the waves will have serious punch. Trez Hir is a reef, so it should handle this long-period energy beautifully.

After that, Monday the 21st gets messy with strong cross-shore winds, and it looks like we hit a wall of nothing for a couple of days. The swell tries to come back around Friday the 25th and Saturday the 26th. Saturday afternoon the 26th sees a massive 12ft WNW swell with a 14-second period and very high energy at 4879. The wind is cross-offshore, keeping things clean. This is a huge, long-range forecast, so treat it as promising but definitely not set in stone. Again, only for the experts.

So, to sum it up: your best bets are this Sunday the 13th morning for a really fun, manageable swell, and then keep an eye on that Sunday the 20th morning for a big, clean groundswell session. The very end of the forecast window on the 26th could be insane if it holds.

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.
