The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Dondra over the next couple of weeks.
Right off the bat, we’ve got a long stretch of small, troubled surf. The first few days are a bit of a write-off, to be honest. Monday the 10th and Tuesday the 11th serve up rideable 4ft to 6ft swell from the south, but the wind is a messy cross or cross-off with a moderate breeze, and there’s a risk of thunderstorms. The water is a warm 81°, which is pretty much normal for this time of year. The real issue is the energy is all over the place, with combined energies ranging from 1443 to 2137, which is moderate to strong, but the consistency is poor and the conditions are just marginal. The 14th through the 17th are even weaker, with swell dropping to 2ft to 4ft, and the energy levels fall off a cliff, barely hitting 600 to 900. That’s weak stuff, and the wave comment says it all – marginal. Surfing is going to be a real grind through this period.
Now, I’m not gonna lie, if you’ve got patience, there’s a serious payoff. The standout window for this whole forecast is from Tuesday the 18th through to around Thursday the 20th. We’re looking at a solid 7ft to 7ft groundswell from the SSW with a long period of 16 to 19 seconds. The combined energy jumps to massive 3294 and 3312 – that’s very strong energy. The wind stays clean, cross-off from the west, so the wave faces should be holding up nicely. This is the real deal. The swell is a bit too big for beginners, but for the rest of you, this is the best on offer. The very long period (over 15 seconds) means this is a proper groundswell, so the reef at Dondra is going to love it. The shape should be quality, with longer gaps between sets. Keep in mind, this spot is inconsistent and can get crowded sometimes, so be early for your session.
After that, the swell holds a bit through the 21st and 22nd, with 6ft to 7ft of SSW swell, still with strong energy (over 1800), but the wind stays solid. It’s still good, but not the outstanding peak of the 18th and 19th. By the 23rd, we start to see it drop back, and the last few days of the outlook are back to that 4ft to 6ft range with moderate energy, and the risk of thunderstorms returns. The window of opportunity is clear, but it’s narrow.
So, do yourself a favour and mark your calendar for the 18th and 19th of August. That’s the one to chase.
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.
