The Lowdown
Alright, Rusty here. Let's take a look at what's on the menu for the next couple of weeks.
Honestly, it's a bit of a mixed bag. We've got a solid, consistent south-west groundswell running for the first week or so, but that onshore cross-off wind from the west never really lets up. It's keeping things bumpy and wonky. The water temp is sitting at 82°, which is pretty much bang on average for this time of year, so you won't need a steamer.
The standout window looks like the second week, particularly around the 18th and 19th of August. The swell picks up again from the south with a solid period, and the combined wave energy hits the 2000s (2337-2500), which is strong. The wind drops slightly, especially on the Tuesday afternoon, making those afternoons your best bet. The swell will be around 4ft to 5ft from the south with a period of 15-17 seconds, giving the waves some real grunt. It's still going to be a bit ragged with that west wind, but it'll be the most powerful and consistent surf of the whole outlook. For the intermediate crew, that's where you want to be. The long-period south swell will wrap in nicely at Dondra, though it might close out a bit if you're on a beach break, but as a reef setup, it should handle that energy well.
Earlier in the run, from the 4th through to the 11th, the swell is there, consistently between 4ft and 6ft from the SSW and S, mostly with a long period over 15 seconds. The wave energy is high, often pushing past 2000. But that fresh to moderate westerly breeze is cross-off, which means it's not going to be clean. It's surfable, but it's not glassy. The risk of thunderstorms is a daily factor too, which can mess with the surface. The bigger days around the 8th (6ft) might be a bit much for beginners, and the long period will make those sets sweep in fast.
After the 13th, the swell really backs off, dropping under 3ft, and the energy levels tumble to below 1000. Those few days are pretty flat and weak.
The only spot on the map is Dondra. It's a reef break here in Sri Lanka, exposed to that south-west swell. It's listed as inconsistent, which fits with the weak patches we see. It can get crowded sometimes, so don't expect to have it to yourself.
To be straight with you, there's nothing in this period that I'd call a classic. The best of a mediocre lot is the 18th and 19th of August. Keep an eye on that window – the wind might ease just enough to make it worthwhile.
Rusty.

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.
