The Lowdown
G’day, I’m Rusty, and I’ve got the surf outlook for Dondra right here. This reef break is a bit of a tricky beast – it’s inconsistent, so you can’t just rock up and expect magic. The forecast starts on Thursday, 10 September, but don’t get too excited just yet.
The first few days are a bit of a washout, honestly. Thursday afternoon kicks things off with a 5ft SSW swell, but that’s carrying a cross-shore wind and a cross-chop that’ll leave the surface messy. The wave energy is strong at 1532, but the conditions are marginal. It’s not worth paddling out for.
Friday (11 September) and Saturday (12 September) keep that same 5ft to 7ft SSW swell, but the winds are still cross or just barely cross-off. Those storm risks don’t help the vibe. The water temp is a warm 84°, which is about average for the time of year, so no surprises there.
Now, here’s the first glimmer of hope. Saturday afternoon the wind shifts cross-off, and the conditions turn clean. The swell holds at 7ft from the SSW with a long 17-second period – that’s proper groundswell energy. The combined swell energy is sitting at 2712, which is strong. This is the best bet for the near term, but remember, this spot is inconsistent, so you’ve got to pick your window.
Sunday (13 September) through Monday (14 September) stay clean with cross-off winds, but the swell drops off to 5ft and then 4ft. Still, with a long period of 18 seconds on Monday morning, those sets will be lonely but powerful. Paddling out will be easier between the lulls.
The real standout is Thursday, 17 September. Finally, we get a solid clean wind (cross-off, light breeze at 9 mph) paired with a 6ft SSW swell, 16-second period, and the description says “excellent surf conditions for experienced surfers.” The energy is solid at 1419. For a break that’s usually marginal, this is the one to circle on your calendar. The swell is under 8ft, so it’s doable for a strong intermediate, but the long period (over 15 seconds) at a reef break like Dondra means it could wall up nicely. Just be aware of the crowds – they come around sometimes.
The second week gets a bit messy. From the 19th to the 21st, we’re looking at more storm risks and fresh breezes, with swells around 6ft to 6ft. The energy stays moderate to strong, but nothing screams “go now.” By the 22nd and 23rd of September, the swell jumps to 8ft, but the period drops to 8 seconds, and by the 23rd it’s a short 7-second windswell. That’s sloppy, choppy, and only for the die-hard crew. From the 24th onwards, the energy plummets below 1000, and by the 25th we’re looking at poor conditions with a cross-shore wind and lumpy chop.
Honestly, the best window is the 17th of September. That’s your standout. The earlier clean spells on the 13th and 14th are worth a sneaky session if you’re local, but the 17th has the quality. After that, it’s a lottery.

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.
