The Lowdown
Alright, let’s talk Dondra. It’s the only game in town for the next 16 days, and it’s a reef break that doesn’t fire all the time, so you gotta be patient. The water’s about average temp for this time of year.
First chance to paddle out is Thursday, 27 August. We’ve got a 6ft swell from the SSW, with a super long period of 17 seconds, and the combined energy is a massive 2855 (strong wave energy). The wind is cross-shore in the morning with storms around, but the afternoon cleans up with a cross-off wind, dropping to 5ft. For a reef, that long period will give you some nice, drawn-out waves. Crowds can be a thing here sometimes.
Friday, 28 August, and Saturday, 29 August, are similar. Swell from 4ft to 5ft, period drops to 13-15 seconds, and the wind is mostly cross-off in the afternoons. The energy is moderate (649 to 1048). It’s marginal, but you could get a session in.
Sunday, 30 August, the afternoon brings a 5ft swell with a very long period of 18 seconds, and energy of 2063 (strong wave energy). The wind is cross-off, and the sky clears. Solid.
The real standout is Monday, 31 August. The morning shows a 8ft swell from the SSW, period 18 seconds, and energy of 3561 (very strong wave energy). That’s a big, powerful groundswell. The wind is cross-off, and it’s clean. This is for experts only – over 8ft, it’s heavy. The afternoon is still 7ft with 2920 energy. Best of the first week.
Tuesday, 1 September, and Wednesday, 2 September, are still good, with swell from 5ft to 7ft, and 15-16 second periods. Energy stays strong (1027 to 2247). Wind holds cross-off. Good, consistent.
From Thursday, 3 September, the swell drops. By Friday, 4 September, it’s 4ft with a short period of 11 seconds, energy at 594. The wind is cross-off, but the quality fades.
Then a gap. From Saturday, 5 September, through Tuesday, 8 September, conditions are poor. Swell below 3ft, period short, and wind is cross-shore. Energy under 500. Nothing to ride.
It picks up Wednesday, 9 September, with a 4ft swell, period of 16 seconds, energy 747 (moderate). Wind is cross-off, so it’s clean but marginal.
The last chance is Friday, 11 September. A 5ft swell with a very long period of 19 seconds, energy 2187 (strong wave energy). Wind is cross-off, but storms possible. Promising, but it’s a week and a half out.
The standout is Monday, 31 August – big, clean, and powerful. Everything else is marginal or poor, with a few decent afternoons. Dondra is inconsistent, so when it’s on, it’s on.

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.
