The Lowdown
Alright, Rusty here, checking in on the Trestraou stretch. Let's see what the next couple of weeks have in store for us.
Right off the bat, it’s a tough start. The first few days are a write-off—tiny, weak, and often messy. We’re looking at a real slow burn before anything gets going. The first real pulse of energy doesn't arrive until around the 28th of August, and even then, it’s a mixed bag.
The best window is shaping up around the 30th of August into the 31st. We’ve got a solid groundswell building, pushing 7 ft from the West on the 28th, but the wind is howling at 25 mph, which is just too much. By Sunday morning, the 30th, the swell is a more manageable 5 ft from the West, with a period of 8 seconds. The winds are offshore, swinging out of the SW at 16 mph, which is a big positive. The combined energy is moderate (270), and it’s the first time the surf report says it’s "surfable." It’s not perfect, but it’s the best we’ve seen so far. The water temp is a touch warmer than normal at 66°, which is nice.
But the real standout, the one that has my attention, is Tuesday the 8th of September. This is a long-range call, so take it with a pinch of salt, but the numbers are wild. We’re looking at a massive 10 ft groundswell from the WNW with a very long period of 17 seconds. The combined energy is a staggering 5127, which is some serious ocean power. The wind looks clean, and Trestraou is a sheltered spot, so that long-period groundswell will wrap in nicely. This is definitely not for beginners—over 8 ft, it’s expert territory. The 10-second period on the 7th should ease the paddle out, but the 8th is a beast. The first week of September has some smaller, cleaner days, particularly the 7th with glassy conditions, but the 8th is the prize.
So, the pattern is: a long, flat, and frustrating first week, then a build-up into some messy but surfable waves at the end of August, leading to a potentially epic, powerful groundswell event in the second week of September. Keep your eyes on the 8th, but don't get your hopes up too high until we get closer.
Rusty.

Information about the Trestraou Surf forecast
The above surf forecast table for Trestraou provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trestraou can be found by selecting the local surf guide option on the grey menu. Our Trestraou 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 (Trestraou) 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 Trestraou 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.
