The Lowdown

Alright, grab a coffee and settle in, it’s Rusty here. Gonna be straight with you – the next couple of weeks at Tronoen are a real mixed bag, and honestly, for a lot of it, you’ll be better off doing something else. Let’s walk through it.

The water is sitting at 63°F, which is a full degree Fahrenheit colder than normal for this time of year. So, you’ll want that extra rubber.

We start off with a bit of a whimper. Wednesday the 26th offers a tiny 2 ft from the west, but with a stiff 19 mph south-easterly, it’s just messy. The combined energy is a weak 60, so there’s nothing to get excited about. Thursday the 27th sees a bump to 4 ft, but it’s a short-period, wind-swell combo from the southwest with a cross-on breeze, creating a choppy, poor surface. That feeling hangs around through Friday and Saturday, with the swell jumping up to 8 ft and then 10 ft on Saturday the 29th. The wind is onshore and strong, with the combined energy hitting 682 on Saturday morning and 1068 by the afternoon. That’s a lot of power, but it’s all wind-chop, and at that size, it’s for experts only, and even then, the quality is just not there. Sunday the 30th is still big and blown out, with a risk of thunderstorms.

The start of next week doesn’t offer much relief. Monday the 31st has 8 ft of west swell, but it’s cross-on and choppy. The combined energy is a beastly 1075, but it’s all for show. The first real flicker of hope comes on Saturday, September 5th. The morning looks clean with a light offshore breeze from the east-northeast, pushing into a 4 ft west-northwest swell with a 9-second period. The combined energy is a moderate 202. This is the best window in the whole forecast. The conditions are described as “clean,” and the score is a solid 2. The break is Tronoen, exposed to the west-southwest, and the swell direction is a decent match. The water is still cold, but the wind is kind. This is your standout.

Sunday the 6th morning has a similar 4 ft, but with a cross-off breeze, it’s still rideable, though the energy drops to 252. After that, the swell fades out. By Tuesday the 8th, we’re down to 2 ft with a weak 61 energy and a cross-shore wind. The last gasp is Wednesday the 9th, with a 5 ft west-northwest swell and a cross-off wind, giving a clean surface and a combined energy of 535, but it’s a marginal call. After that, it’s a very small, fading end to the period.

So, to sum it up: the one true standout is the morning of Saturday, September 5th. Get it while you can. The rest of the run is either too small, too windy, or too big and raw. The crowds at Tronoen can be an issue sometimes, but on that Saturday morning, with the offshore wind, it might be worth the gamble.

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.
