The Lowdown
Alright, Rusty here. Let's break down what's cookin' for Dondra over the next 16 days. The story here is mostly a steady cross-off breeze from the west-northwest, which keeps the surface clean, but the swell and energy have a real up-and-down vibe.
Water temp is 28°, right on the money for this time of year, so no need for a thick suit.
We kick off Saturday the 1st of August with a solid 10ft swell out of the west, but only a 9-second period. That's a lot of beef without the backbone, and with a 22 mph breeze, it's gonna be a messy, lumpy ocean. The wave energy is a huge 2213, so there's plenty of power, but not for a clean paddle session. This looks more like a kiteboarding day.
Sunday the 2nd comes down to 8ft from the west, period up to 10 seconds, still that cross-off. Cleaner, but still a strong breeze. Energy is 1529.
Monday the 3rd gives us 7ft, 11-second period from the west-northwest. Risk of thunderstorms, but the surface stays clean. Energy drops to 1666.
Now, here's where it gets interesting. From Tuesday the 4th, the swell drops to 5ft, but swings to the south-southwest with a very long 16-second period. That's proper groundswell. Energy is moderate at 1474. This pattern of south-southwest, long-period swell sticks around for a good while. Wednesday the 5th has 5ft at 15 seconds, energy back up to 1821. Thursday the 6th has 5ft at 17 seconds, energy at 1897.
The real standout has to be Saturday the 8th of August. We get a 7ft south swell with a 17-second period, and the combined energy hits a massive 2794 – the highest for the whole forecast. The cross-off wind is still there, but it's manageable. That long-period south swell is going to wrap into Dondra's reef beautifully. Just keep in mind, Dondra is an inconsistent reef setup, so conditions need to be right, and this is as right as it gets.
After that, it fades. From Wednesday the 13th onward, the energy drops below 1000 at times, with smaller swell from the south-southeast and shorter periods. Still clean, but the power's gone. The 16th has a 5ft blip from the west with a 7-second period, but that's choppy.
Bottom line: pencil in Saturday the 8th of August. That's your session. The rest of the window has some clean, fun waves in that 4-5ft range, especially the early part of the second week, but that Saturday stands head and shoulders above the rest. Stay safe on that reef.
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.
