The Lowdown
Alright, folks, let's get into it. Water temp is a balmy 29° – that's a bit above the usual for this time of year, about a degree and a half, so you can leave the full wetsuit at home.
The surf this week is nothing to write home about, but there's a couple of pulses. We're starting Wednesday morning with a clean 1.3m at 14 seconds, with a sweet west cross-off breeze. There's some energy there, a moderate 1359. It's a bit weak, so you'll be hunting for the sets.
The next few days, the wind goes more westerly-southwest and brings some cross-shore chop. Thursday and Friday are messy, with 1-1.5m waves, but the wind gets jumbly and it's hard to find a clean wave.
Saturday, the 19th, is a bit bigger. The swell builds to 1.9m in the morning and 2.2m in the afternoon. The period is holding at 16 seconds, and it's a cross-off breeze. The energy is up there, 2319, so there's some push. But it's still only just about a 3 out of 10, so the banks are a bit iffy.
Now, the standout. That’s the 26th of September. Saturday. The swell jumps to 2-2.3m, but the big news is the period – a long 20 seconds. This is proper groundswell, with a huge energy reading of 4198. It's meaty. The downside is the wind is more cross, not properly offshore, so there's a bit of chop on top. It's going to be a serious session.
Everything between now and then is pretty marginal. Around the 22nd to the 25th, it's small and messy, but mostly, it's all a bit "meh." The last good chance is the 1st of October, with a 1.5m southwest swell and 19-second period. The wind is cross-off, but there might be some leftover storm energy.
So, there you have it. A couple of windows, but don't expect a classic run. That Saturday the 26th looks like the pick, with that long, strong groundswell. It's big, so be sure you know what you're doing.

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.
