The Lowdown

Right then, let’s talk about Tronoen. We’ve got a bit of a slow-burner here. The overall pattern is one of small, messy surf for the first week and a half, with a few mornings that are clean but sadly lacking in any real push. Then, around the second week, things finally start to build, and there’s a couple of standout sessions that’ll be worth the wait.

We kick off Friday the 7th with tiny 1-foot waves from the west, period at 9 seconds. The morning is glassy with a light easterly, but the energy is next to nothing (29). It’s flat, really. That carries on through the weekend – Saturday the 8th morning has a little bump to 1 feet from the north-west with a longer 11-second period, but the combined energy is still weak (40). The wind is light and clean, but it’s just not enough.

Monday the 10th morning is the first time we get a sniff of something surfable. The swell is 2 feet from the north-west, and the wind is a light offshore, keeping it clean. The energy is still modest (94), but hey, it’s a wave. The rest of that week is a frustrating mix of small, clean mornings and windy, choppy afternoons with onshore winds wrecking the surface.

Now, let’s talk about the real action. The first proper standout is Tuesday the 18th morning. The swell jumps to 6 feet from the west, with an 8-second period. The combined energy is solid (458), and the wind is a light offshore from the east-southeast. This is clean, punchy, and has some grunt. It’s not huge, but it’s the best we’ve seen by a long shot. The following morning, Wednesday the 19th, is almost as good – 6 feet from the west-northwest, clean with a glassy light easterly breeze (389 energy). Both mornings are for intermediate surfers as the swell is over 5 feet, but not too big for a good time. The water temp is 65°F, which is about average for this time of year, so no need for a thick wetsuit.

The long-range standout to keep an eye on is Saturday the 22nd morning. The swell is a solid 8 feet from the west, with a 9-second period. The combined energy is massive (1194), but here’s the catch – the wind is moderate cross-shore, creating some chop. This is a big, powerful swell over 8 feet, so it’s one for experienced surfers only. The quality is a bit iffy with the wind, but the raw energy is undeniable. It’s a promising but less certain call, being so far out. Crowds are listed as "sometimes" at Tronoen, so on these standout days, expect some company.

To be honest, outside of those two mornings on the 18th and 19th, and the potential on the 22nd, it’s a lot of ordinary, small, and windy surf. The setup is a beach, so when the swell is decent but the wind is onshore, it’s more interesting for kite surfers than paddle surfers. The early part of the forecast is a real blank run, with nothing worth paddling out for until that Monday the 10th. But the second week finally delivers.

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.
