The Lowdown
G’day, Rusty here, and I’ve been staring at the charts for Dondra. This one’s a slow burner, but once it fires, it’s got some serious grunt. Dondra is a reef break, and it’s inconsistent, so when it turns on, it’s a proper treat. The water temp is sitting around 81°, which is about normal for this time of year, so no surprises there.
The first few days are a bit of a write-off. We’ve got a risk of t-storms on Wednesday the 12th and a sloppy cross-shore wind, with swell around 3 ft from the south—period is a long 16 seconds, but the energy is only moderate (962). It’s just not clean enough. Thursday and Friday are cleaner with cross-off winds, but the swell stays small, around 3 ft to 4 ft, and the energy is still moderate. You could get a few if you’re desperate, but it’s not worth the paddle.
Then we hit the weekend of the 16th and 17th. Sunday the 16th afternoon sees a shift, with the swell coming from the west at 4 ft, period 10 seconds, and the energy is moderate (692). Still not magic. But look at Monday the 17th afternoon—the swell jumps to 4 ft from the SSW, but the period is a massive 21 seconds, and the energy is strong (1324). That’s a proper groundswell, and it’s clean with cross-off wind. The reef at Dondra should handle that long period beautifully.
Now, the standout. Tuesday the 18th. This is the one. Both morning and afternoon, we’re looking at 8 ft from the SSW, period 19 seconds, and the energy is very strong (4352 and 4187). That’s a lot of water moving. The wind is clean cross-off from the west. This is a big session, but it’s over 8 ft, so this is for experienced surfers only. The swell direction is matching the optimum SW direction, so Dondra will be lined up. Wednesday the 19th holds similar size and energy, also a strong call.
After that, it slowly drops off. Thursday the 20th and Friday the 21st still have decent size—7 ft and 6 ft—but the wind gets a bit cross on the mornings, making it choppy. The afternoons clean up. The energy stays strong through to the 24th, but the quality dips. The 24th has a 7 ft SSW swell with a 16-second period, clean wind, and strong energy (2533), which is a solid backup.
The very end of the window, the 26th and 27th, sees a return of long-period SSW groundswell (20-21 seconds) with clean cross-off winds, but size is only 4 ft to 5 ft. Still fun, but not the highlight.
So, clear best: Tuesday the 18th and Wednesday the 19th. Big, clean, and powerful. If you’re an expert, that’s your window. The reef will be doing its thing, and with that long period, expect proper, grinding lines. Just remember, it’s inconsistent overall, so don’t sleep on it.
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.
