The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s headed our way at Dondra. This is a reef break that’s pretty inconsistent, so don’t expect a wave every day, but when it does come, it’s got some real grunt. The water is sitting at 84°, which is a touch warmer than normal for this time of year – nothing wild, but you’ll notice it’s a bit balmier than usual.
Right now, Monday morning, it’s not looking great. We’ve got a 3 ft swell from the SSE with a short period, cross-shore wind, and the wave energy is moderate (461). The report says poor surf – honestly, I’d give it a miss. That pattern carries through the week. Monday afternoon and Tuesday morning are still poor, though Tuesday afternoon shows a little promise with the wind turning cross-offshore and the swell bumping up to 3 ft from the SSW with a long 16-second period. The wave energy is moderate (569), and the wind is cleaning it up. It’s still marginal, but you might snag a few if you’re keen.
Wednesday and Thursday are more of the same – marginal, with cross-off winds and swell heights around 3 ft to 5 ft. The energy is building, hitting 1404 on Thursday morning, which is moderate to strong. Thursday afternoon sees 5 ft from the SSW with a 17-second period – that’s a long-period groundswell, and for a reef break like Dondra, that’s a good thing. The wind is clean, but the overall score is still only a 3 out of 10, so it’s not firing.
Friday through the weekend, we see the swell really ramp up. Friday morning has 5 ft from the SSW, 15-second period, and the energy is strong (1989). The wind is cross-off, so it’s clean. But keep in mind, with a 15-second period, the sets will be spaced out, and the wave shape should be good for a reef. Saturday morning is the real standout: 7 ft from the SSW, 17-second period, and the energy is very strong (2652). That’s solid, powerful swell. But here’s the thing – at 7 ft, it’s getting into expert-only territory, especially on a reef. Saturday afternoon pushes 7 ft, still clean with cross-off winds. This is the best on offer: Saturday, 12th September. The swell direction is SSW, which matches the optimum SW direction pretty well, and the wind is clean. It’s inconsistent, so don’t expect a constant wave, but when the sets come, they’ll be worth it. Crowds are possible, so keep an eye out.
Sunday the 13th backs off a bit to 6 ft, still clean, but the energy drops to 1646. It’s still good, but not as punchy as Saturday. The following week, from Monday 14th through to Wednesday 16th, we’ve got a mix of 4 ft to 6 ft, clean winds, and strong energy. The 18th September Friday morning has 4 ft, but the afternoon brings a 3 ft swell with a very long 19-second period – that’s a super long-period groundswell. The energy is strong (1663), but that period will make the waves fat and straight at a beach break, but on a reef, it might wrap in nicely. Still, it’s marginal.
Then the 19th and 20th September – Saturday and Sunday – the swell jumps to 7 ft and 8 ft from the SSW. That’s big, expert-only territory. The wind turns cross-shore, and the report says fresh cross-shore with lumpy cross-chop, so it’s going to be messy. The energy is massive – 3822 on Saturday afternoon – but the quality is poor. That setup looks more interesting for kite surfing than paddle surfing, honestly.
The 21st and 22nd September drop back to 5 ft to 7 ft, but the period drops to 8 seconds on the 22nd, which is short-period windswell, so the wave quality will be poor. The wind is cross-off, but it’s just not the same as the earlier groundswell.
Overall, the standout is Saturday the 12th and Sunday the 13th September. Saturday morning has that 7 ft, 17-second groundswell with clean winds – that’s the pick. For anyone who’s not an expert, Thursday afternoon the 10th with 5 ft and clean winds might be a bit more manageable. But remember, Dondra is inconsistent, so don’t expect a wave every day – it’s a waiting game. The forecasts are more reliable for the first week, so lock in those dates if you can.
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.
