Alright folks, Rusty here. Let's chew the fat on what's coming down the pipe, just between us and the data.
The only spot worth talking about is Dondra, a reef set-up that needs a south-west swell. The water's at about 81°F, which is dead average for this time of year, so no weirdness there.
Right, the first week from Monday the 13th through to Sunday the 19th is a bit of a snooze. Wave heights are hovering around 3ft to 4ft. The period is decent—lots of it sitting between 11 and 18 seconds—but there's a persistent cross-off breeze from the west at 15 to 18 mph. It keeps the surface tidy, but the overall energy is only low to moderate. You'll see the combined energy figures hanging between 405 and 1002, but the take-home is "marginal." Don't bother paddling out for that.
But then, things wake up around Monday the 20th. We get a proper push of south swell, with heights hitting 4ft and the period stretching out to 17 seconds. The energy number jumps to a solid 1436, which tells you there's some real grunt behind it. The wind stays cross-off but drops to about 12 mph, which is a real bonus.
The clear standout is Tuesday the 21st. We're looking at a consistent 5ft swell from the south, with a period of 14 to 15 seconds and energy over 1000. The wind is still cross-off from the west, keeping those lines clean. Now, Dondra is a reef break and it can be inconsistent, so you'll be waiting for the good ones, but those waves will have some proper shape.
There's another bump on Saturday the 25th with 5ft waves, but it's from the west with a short, choppy 10-second period. That's going to be fat and crumbly.
So, to sum it up: a flat start, then a cracking couple of days on the 20th and especially the 21st. After that, it fades. Get on it while it's good.
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.
