The Lowdown
Alright, Rusty here. Let’s talk about what we’ve got coming up at Dondra.
First off, the water is sitting at 84° – a touch warmer than normal for this time of year, so you can leave the wetsuit at home. That’s a nice bonus.
We’ve got a long run of surf ahead, but honestly, it’s a tough one to call a standout. The pattern is persistent: a solid, long-period groundswell from the SSW is hanging around for days, with combined wave energy mostly in the strong range – numbers like 1706 and 1610 tell you there’s plenty of juice. The problem is the wind. It’s cross-offshore from the west, blowing at 16 mph most mornings and afternoons, which keeps things looking clean on paper but that wind strength is constantly on it, limiting the real quality. The swell is mostly 5 ft to 6 ft, with periods of 14 to 18 seconds – that’s proper groundswell, and at a reef break like Dondra, that long period can mean some real nice lines. But with that steady breeze, it’s never gonna be glassy perfection.
Sunday the 13th through to Tuesday the 15th is your most consistent window, with swell in the 4 ft to 6 ft range and clean conditions. It’s marginal, but doable. The best chance is probably Sunday morning: 6 ft from the SSW, period 16 seconds, combined energy 1706 – that’s decent grunt, and the cross-off wind keeps the face manageable. For an intermediate surfer, that’s the go. Keep in mind Dondra is inconsistent, so you might have to wait for the sets, but when they come, they’ll have some push.
Then we hit a rougher patch. From Saturday the 19th onward, the wind picks up to 19 mph, and by Sunday the 20th it goes full cross-shore, with lumpy cross-chop and scores dropping off a cliff. That setup looks more interesting for kite surfing than paddle surfing, to be honest. Swell size bumps up – 7 ft on Saturday the 19th afternoon, and a big 10 ft on Monday the 21st morning – but that’s expert territory only, and the wind is just messy.
After the 23rd, it gets worse: poor surf conditions, lumpy chop, and weak energy – numbers drop below 900. There’s a small window on the 27th and 28th with cleaner cross-off wind and 4 ft to 4 ft SSW swell, but the energy is only moderate (925 to 1236). It’s a long wait for nothing special.
So, if you’re going to paddle out, aim for this Sunday the 13th or Monday the 14th. That’s your best shot. The rest is a grind.

Information about the Dondra Surf forecast
The above surf forecast table for Dondra provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dondra can be found by selecting the local surf guide option on the grey menu. Our Dondra 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 (Dondra) 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 Dondra 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.
Dondra is 8 km (5 miles) from Matara. If you plan a holiday in West Sri Lanka, look for hotels and other accommodation in Matara. Matara has rooms for a wide range of budgets as well as car hire and transport links.
