The Lowdown
Hey, Rusty here. Let’s break down what Tronoen is serving up.
The first few days are pretty quiet, but things get going on Saturday the 5th. That Saturday morning is the clear standout. The swell is coming from the WNW at about 7ft, with a very long 13-second period. That’s real groundswell energy, and the combined swell energy is strong at 1253. Winds are light and cross-offshore from the ESE at 6 mph, so it’ll be clean and lined up. This one is for experienced surfers. Crowds are possible here sometimes, so grab it early.
Water temp is around 64°, which is normal for this time of year.
The rest of Saturday and Sunday drop off in quality. Monday the 7th morning brings more size – 8ft from the west, 12-second period – but the wind is a messy cross-shore at 16 mph, making it choppy. That kind of setup might be better for kiting than paddling.
Tuesday the 8th morning hits 8ft from the WNW, but again, the cross-shore wind keeps it from being clean. That’s expert-only territory. By Wednesday the 9th, it drops to 6ft.
Then we hit a quiet patch. From Thursday the 10th through Monday the 14th, the surf stays small and mostly poor – under 3ft with choppy onshore winds. Not much to get excited about.
The next good window is Tuesday the 15th morning. A 5ft WNW swell with an 11-second period, light offshore breeze from the ENE at 9 mph, and clean conditions. Combined swell energy is 507 – moderate but well-aimed. Worth a look if the forecasts hold.
Wednesday the 16th morning is also a gem for small-wave gear – 3ft with glassy offshore wind from the east. Clean, fun, and uncrowded potential.
After that, the outlook fades into small, ordinary surf. So: Saturday the 5th morning is your top pick. Tuesday the 15th morning is the solid backup.
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.
