The Lowdown
Alright, crew, Rusty here with the long-range look. And I gotta tell ya, it's mostly flat, flat, flat out here for Trez Hir. The next sixteen days start with a big ol' empty ocean. We're looking at a long stretch of no-good, flat conditions from the start all the way through the middle of next week.
The water temp is about normal for the season at 65°F, so no surprises there. But the swell is just not there. We're talking ankle-biters in the 0.3ft to 2ft range. Don't even bother waxing up.
The first sign of anything with a pulse arrives Wednesday afternoon, the 19th. A WNW swell rolls in with waves around 5ft, and the energy is moderate at 443. With a light cross-off breeze, it should be clean. It's not gonna blow you away, but it's a start.
But the real show is on Thursday the 20th. The swell fills in nicely to a solid 6ft with a period of 9-10 seconds. The energy is strong, hitting 531 in the morning and a very hefty 1000 by the afternoon. With offshore WNW winds, this is the day. Clean lines, some power behind 'em. This is your stand-out session. It's a bit chunky for the beginners, but for the rest of us, it's the best we're gonna get for a while.
Then, just as quick as it came, it's gone. Friday the 21st drops to 2ft, and we're back to the drawing board. There's a messy attempt at a swell on the 28th with 5ft WNW waves, but the onshore winds will chop it up and ruin it.
The final glimmer of hope is on Monday the 31st. Another WNW pulse, with 5ft to 5ft waves and a longer 11-second period. The energy is solid at 450-620, and the offshore winds will keep it clean. It's a promising look, but it's a long way off, so keep your expectations in check.
Bottom line: If you want waves, circle Thursday the 20th on your calendar. That's the one. The 31st is a distant second.
Rusty out.

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.

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.
