The Lowdown

Alright folks, Rusty here. Let’s break down what’s happening on our stretch of coast.

We’re starting off with a slow, weak grind. Wednesday morning brings a tiny bit of ankle to waist-high surf, around 3 feet, but it lacks any real punch. The wind is offshore and clean, which is nice, but the swell is short-period and weak. It’s a paddle, not a session. Wednesday afternoon is the same story, just a bit weaker.

Thursday and Friday are a wash. The winds turn cross-shore and chop things up, while the swell stays small and unorganized. You’ll find it hard to get a clean wave, and the energy is just not there. The water temp is sitting at 63°, which is about normal for this time of year.

Now, pay attention, because things get interesting soon.

Friday morning is our first real taste of action. The swell jumps to about 5 feet from the west with a 10-second period, and we've got light offshore winds. The energy jumps up to a strong 463, a massive leap from where we've been. This is the best surf of the first week so far. It's proper size, but still manageable for most surfers who know what they're doing. The direction is a bit west of the ideal for this spot, but there's plenty of power behind it.

Saturday morning backs off a touch and gets a bit cross-shore. However, Saturday afternoon and especially Sunday morning are where you want to be. Saturday afternoon has 5 feet of swell, but the period is a long 13 seconds, and the energy is pumping at a big 871. The wind is light and cross-offshore, keeping it clean. The Sunday morning session has even more size, pushing 6 feet from the WNW with an 11-second period, and the energy is huge at 937. That's a serious swell for the experienced surfers. It'll be a big, powerful ocean. The waves will be a bit more lined up, but still a lot of fun. Monday will see it back off considerably.

We’ve got a bit of a lull early next week before another pulse arrives around Friday the 19th and Saturday the 20th. There’s another WNW swell coming through with around 4 feet of surf and good offshore winds. The energy is strong, and the conditions should be clean. This is a promising window, but since it’s a week away, I’d treat it as likely but not set in stone.

Towards the very end of the period, around the 23rd and 24th, the surf just fades. It drops right off to nothing, so if you haven't scored by then, you're out of luck.

The Best Bets:

For the first week, my pick is Sunday morning (September 13th) at Trez-Hir (France). The swell is big, the energy is strong, and the wind is offshore. This is not a day for beginners; this is a surfers' wave. For the second week, keep an eye on Saturday morning (September 19th) at Trez-Hir (France). It has less size but looks to have those clean, off-shore conditions that could make for some really fun, rideable waves.

And a heads-up, Trez-Hir is a spot that doesn't break often. So when it lines up like this, you've got to be there.

That’s the long and short of it. The middle of next week looks flat, so don't get caught out. Get your sessions in while you can.

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. 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.
