The Lowdown
Right, let’s have a look at what’s on the table, yeah? Over the full sixteen days, Tronoen is our only option, and it’s a bit of a mixed bag. For the most part, this spot will be doing its thing with cross-onshore breezes and lumpy conditions. It’s not your picture-perfect week, but there’s a couple of windows worth waiting for.
The Monday the 19th kicks off a subtle change, with swell picking up to around 3 ft from the WNW. Combined wave energy sits at 205 (moderate), and the period stretches to 9 seconds. It’s a solid step up from the tiny stuff early in the week, but the wind keeps it messy. By Thursday the 22nd, we get a decent surprise: a clean, cross-offshore breeze with only 3 ft of swell (NW, 7-second period). Energy is at 107 (weak), so it’s more of a longboard or funboard day, but that clean surface makes up for a lot. The date for that is Friday? No, it's Saturday morning the 22nd – mark it. It’s the first real chance to enjoy the water without a fight.
Looking further ahead, by the morning of Sunday the 23rd there’s a beautiful offshore wind with a clean surface, but the swell is tiny – just 1.0 ft to 1 ft. Not worth paddling out for unless you’re just floating.
The standout – if there is one – comes late in the run. Saturday the 29th afternoon has a solid 10 ft swell from the WSW, 8-second period, and a combined energy reading of 1232 (strong). That’s serious power. However, the wind is cross-onshore and choppy, so it won't be pretty. For experienced surfers only at that size, and you’ll be dealing with a lumpy surface. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
No break gets a gold star here. The best on offer is that Saturday morning the 22nd slot at 3 ft (NW) with clean conditions – small but rideable. For everything else, the wind just works against us.
Stay patient, mates. Forecasts can turn.

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.
