The Lowdown

Hey folks, Rusty here. Let’s get into it. We’ve got a tough stretch ahead for our area, so I’ll keep it real. Right now, the surf is tiny and messy, and honestly, the whole 16-day window is a bit of a struggle. There’s a noticeable gap in decent surf for the first several days, so don’t rush out.

Looking at Tronoen, the first recommendation doesn’t really come until Tuesday 28 July. Up until then, from Tuesday 21 July onwards, it’s a desert of poor surf, with tiny waves, choppy winds, and no real energy. The combined swell energy is weak, rarely breaking past 40 (moderate energy only appears briefly on Sunday 26 July with 276, but it’s cross-onshore and lumpy, so not a good look). For a few days, there’s literally nothing worth paddling for.

The standout in this whole period is Tuesday morning, 28 July at Tronoen. The swell is 4ft from the NW at 10 seconds, which is a nice groundswell. The wind is light and offshore from the E, so it’ll be clean. The combined energy sits at 269 (moderate), so there’s some push. The water temp is 68°F, which is much warmer than usual for this time of year – a solid 4°F warmer than average, so you can leave the thicker wetsuit at home. This is the best on offer, but it’s not a world-beater. The break is fairly consistent, but with a WSW optimum swell direction, this NW swell is a bit off-angle, so it might not be perfect. Still, the clean conditions make it the pick.

Thursday 30 July afternoon is another one to keep an eye on. The swell is small at 3ft from the WNW with a 10-second period, but the wind is glassy – dead calm – and the combined energy is 124 (moderate). It’ll be tiny, clean, and very user-friendly. Surfable, but don’t expect much push.

After that, the weekend of 1-2 August looks pretty average with onshore winds and choppy waves, and the energy stays weak to moderate. The following week, 3-5 August, is mostly poor surf conditions with small, short-period waves and onshore winds. Nothing to get excited about.

Overall, the best bet is that Tuesday morning session on 28 July. It’s not a classic, but it’s the only clean window with any real energy. If you’re desperate for a paddle, that Thursday 30 July glass-off might be worth a go, but keep expectations low. The rest of the time, leave the board in the shed. This is a quiet period for our area, so it’s more normal to have a blank run. Forecasts can change, but right now, patience is the name of the game.

Rusty.

Information about the Tronoen Surf forecast

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

Tronoen is 13 km (8 miles) from the city of Loctudy. If you plan a holiday in Finistere - Brittany, look for hotels and other accommodation in Loctudy. Loctudy has rooms for a wide range of budgets as well as car hire and transport links.
