The Lowdown

Alright folks, Rusty here. Let's break down what's cooking for the Dondra area over the next couple of weeks. It's been a bit of a mixed bag of signals, but there are a few windows worth paddling out for. The water temp is sitting at 84°, which is only a tick warmer than usual for this time of year, so nothing weird going on there—just your typical warm tropical bath.

The first real chance to wet a line kicks off on Friday the 11th. We've got a moderate cross-shore wind and a bit of a cross-chop, but by the afternoon the wind swings cross-offshore and the conditions clean right up. Swell is coming in from the SSW at 5ft with a long 14-second period, giving the wave some real grunt. The combined energy is sitting at 1626, which is a solid moderate push. It's not going to be perfect, but for an afternoon session on a reef setup like Dondra, it's worth a look if you're an intermediate wanting to avoid the worst of the crowds—though be warned, crowds are sometimes a thing here.

Saturday the 12th is promising but still a touch messy. Morning has a clean 7ft SSW swell with a super long 17-second period (groundswell, plenty of energy at 2853) and cross-offshore wind. That's a lot of water moving around, and for a reef break, that long period will really suck the energy out of the ocean between sets—good for paddling out but the wave will be very lined up. This is definitely in the intermediate-to-expert zone. Saturday afternoon gets a bit more cross-shore again, so make the morning call.

Sunday the 13th keeps the theme going: 6ft SW groundswell, 16-second period, cross-offshore breeze, and moderate wave energy (1556). The afternoon also stays clean with 5ft of swell. It's not the standout of the trip, but it's consistent and ridable for the crew who know the reef.

Now, if you're waiting for the best of the lot, put a circle around Tuesday the 15th. Tuesday morning is the pick of the forecast: 5ft SSW swell, 15-second period, light winds from the west at 9 mph making for a glassy cross-offshore—that's clean as a whistle. Combined energy of 1689 gives it a good solid push without being overwhelming for an intermediate. That's your top window. Just be ready for the risk of thunderstorms, but the wind and waves will be dialled.

Beyond that, the rest of the second week is a bit of a fade. Swell drops back, the periods get shorter, and the winds pick up. From the 18th and into the 20th we see another pulse of SW swell building back to 6ft-7ft, but the period is down to 14 seconds and the wind is a fresh 16-19 mph cross-offshore. By the 22nd, we're into short-period WSW windswell (just 8 seconds) pushing 7ft-8ft—that's expert-only territory, and honestly, with that short period and those winds, the Dondra reef might be more of a wash-through than anything else. The combined energy stays moderate (around 1100-1250) but the quality drops away.

The very tail end of the outlook, around the 25th and 26th, sees a brief return of some long-period SSW swell (18-19 seconds) but the winds shift to cross-shore and get lumpy. Not the best way to finish. There's a clear gap of lower-quality days between the 18th and the next pulse, so don't get too excited for the second weekend unless you're a glutton for punishment.

So the two real standouts are Friday afternoon the 11th for a cleaner evening session, and Tuesday morning the 15th – that's your premium session: glassy, clean, good size, solid period. Mark it.

Stay stoked,
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.
