The Lowdown
Alright folks, Rusty here. Let’s get stuck into the outlook for Tronoen. We’ve got a bit of a slow start, but there’s some real promise if you’re patient.
The first part of the window is a write-off, to be honest. Monday the 7th and Tuesday the 8th are a mess. You’ve got a big, powerful swell hitting on Monday with combined energy of 1256, but it’s straight onshore and the message is clear: marginal at best. Tuesday the 8th is even worse, with gale-force cross-shore winds and a 10ft wall of chop. That’s a no-go unless you’re a masochist.
We get a bit of a lull from Wednesday the 9th right through to Friday the 11th. The swell drops away, but the wind is still all wrong – cross-on and bumpy. The energy is down in the low hundreds, barely a ripple. Nothing to get excited about.
Now, here’s the first real standout. Saturday the 12th morning. The stars almost align. The swell is a modest 2ft from the WNW, but the period is a very long 16 seconds – that’s proper groundswell energy. The wind is glassy, flat calm, which is a major positive here. The combined energy is 423, which is moderate. It’s not going to be huge, but for a clean, glassy morning on a long-period swell, Tronoen could be a gem. The swell direction is a perfect match for the break’s optimum from the WSW. This is the best early call, but it’s a morning-only window.
The rest of that weekend and into the next week is a mix of average conditions. We get a few pulses of 5ft to 6ft swell, but the wind is mostly cross-on or onshore, keeping things choppy. The energy spikes up to 1397 on Saturday afternoon, but the wind ruins it.
The next real highlight is a couple of weeks out. Wednesday the 16th morning is looking very promising. The swell is 6ft from the WNW, with a period of 12 seconds – good, solid groundswell. The wind is a light, clean cross-offshore from the NE, so the waves should be clean and lined up. The combined energy is 805, which is solid. This is a strong, well-shaped swell with decent power and good wind. It’s still a bit far out to lock in, but it’s a definite one to watch.
Then, the absolute best of the whole forecast. Sunday the 20th afternoon. The swell is 6ft from the WNW, period of 12 seconds, and the wind is dead calm – glassy. The combined energy is 733. The wind is zero, so the surface will be like a mirror. The swell direction is right on the money. This is the standout session of the entire 16 days. It’s two weeks away, so treat it as a promising long-range target, but if it holds, Sunday the 20th afternoon will be the day to be in the water. The water temperature is 66°, which is a touch warmer than usual for this time of year.
The following Monday and Tuesday (21st and 22nd) taper off with a dropping swell and cleaner but smaller conditions. The energy drops to 164 and 133, so it’s back to the small stuff.
Alright, that’s the story. The pick of the bunch is that glassy Sunday afternoon on the 20th, with the clean Wednesday morning on the 16th as a solid backup. Keep your eyes on the forecast.
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.
