The Lowdown
Alright, let's have a look at what we’ve got on offer. This forecast covers the next 16 days, and believe me, there’s a bit of a wait, but some real gems if you’re patient.
Right now, and for the first few days, it’s pretty grim. Sunday the 30th is a write-off with strong cross-shore winds and messy, poor surf. Monday the 31st is where things start to look interesting. The standout window for the whole run is Monday morning at Trez Hir. We’re looking at a solid 10ft swell rolling in from the west, with a 10-second period and a moderate offshore wind. The water’s sitting at about 64°, which is about average for this time of year. The combined energy is cooking at 1545 (moderate to strong), and it’s clean. This is excellent surf for experienced surfers – that’s your best bet by a long shot. Monday afternoon is still very good, with 8ft and clean offshore winds, but the morning is the real hero.
After that, Tuesday and Wednesday drop right off into small, weak, and choppy conditions – not worth paddling out for. Thursday the 3rd is clean but only 6ft, still pretty ordinary.
Then on Friday the 4th of September, things fire up again. The morning has clean 8ft swell from the west-northwest with an 11-second period and offshore winds. The energy is big at 1245 (moderate to strong). It’s a little touchy for conditions, but very promising. Saturday the 5th has some clean 6ft swell with light winds, perfect for a fun session without the crowd pressure.
The big one to keep your eye on is Monday the 8th of September. We’ve got a massive 16ft west-northwest swell rolling in with a 12-second period. The combined energy is off the charts at 6411 (very strong). But – and this is a big but – the wind is cross-shore and choppy. This is not for beginners. This is big, powerful, and only for experts. It could be incredible if the wind plays ball, but right now it looks messy. The Tuesday the 11th and 12th of September also have strong, clean 8ft to 8ft swell with offshore winds, building into another great period for experienced surfers.
Keep in mind, Trez Hir is a spot that rarely breaks, so this run is a special treat. The best of the best: Monday the 31st of August morning – no question.

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.
