The Lowdown
Alright folks, Rusty here with a look at what’s coming our way down at Dondra (Sri Lanka). Let’s get into it.
The pattern over this 16-day stretch is a long run of small, marginal waves with a persistent cross-off wind, keeping things clean but pretty weak. There’s a couple of windows where the swell tries to push, but honestly, nothing here is going to get the heart properly racing. The water temp is about average for the time of year, so no surprises there.
The whole forecast is a bit of a flat spell, with only average energy showing up. The best of it looks like it falls on the afternoon of Thursday, the 27th of August, and again on Sunday, the 30th of August. Thursday afternoon brings a 5 ft SSW swell with a 17-second period – that’s a proper long period groundswell, so there’ll be real shape in the waves, but on a reef setup it might line up a bit straight. The wind is cross-off, making for clean, workable faces. The combined energy hits 1639 (moderate to strong). Sunday afternoon has the better size at 5 ft from the SSW, with a long 18-second period and that same clean cross-off breeze. The energy is solid at 1855 (moderate to strong). This is the standout call of the window.
After that, we see a bigger bump on Monday, August 31st, with nearly 7 ft SSW swell pushing through, but the wind picks up and the quality dips. That’s pushing into intermediate territory and beyond. Crowds are always something to keep an eye on here, as it can get busy.
Into the first week of September, we’re holding onto some 5 ft to 6 ft SSW swell with clean conditions, but the period drops off, and the energy fades out. By the second week, from September 5th onwards, the swell turns small and shorter period from the SSE, and the energy drops right off (low to mid hundreds). The wind stays mostly cross-off, but there’s just not enough push.
The final few days from the 7th to the 9th of September are poor to marginal, with tiny, weak surf. It’s a long gap of nothing special. Honestly, this is a period to keep your expectations low and wait for a better chart.
Rusty out.

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.
