The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming down the pipe for the Dondra (Sri Lanka) region.
We're looking at a solid stretch of surf ahead, but it's not all gonna be easy pickings. The early part of the week is dominated by a long-period groundswell, which is excellent news for a reef setup like this. The water temp is sitting at 28°, which is bang on average for this time of year, so no wetsuit worries.
The standout action is definitely the middle of next week. The first real solid pulse comes in on the 18th of August, Tuesday morning. We're talking a solid 8ft swell from the SSW, with a long, powerful 19-second period. The combined energy is massive at 4969, and the wind is holding clean cross-off from the West. This is proper, powerful reef surf. It's pushing into the 8ft mark, so this is one for the experienced crew only. The consistency is an issue here though, as this spot is listed as 'inconsistent', so you'll need to be patient between sets, but the reward will be worth it. This carries through Tuesday afternoon and into the 19th of August, Wednesday, with similar size and energy.
Before that, from the 8th of August, Saturday, through to the 17th, we've got a mix of cleaner but smaller days. The swell is mostly in the 3ft to 6ft range, with those long periods (14-19 seconds) giving it good shape. The wind is predominantly cross-off and clean, which is a major plus. The crowds are listed as 'sometimes' here, so you might have some company. The best of that earlier run looks like Sunday afternoon the 9th of August, with a 6ft S swell and a 17-second period, combined energy of 1938, and clean cross-off breeze. It's a solid option.
Later in the second week, around the 20th and 21st of August, the swell drops back a touch but stays in the 7ft to 8ft range with decent energy. The wind turns a bit stronger at times, a fresh breeze, but still cross-off, keeping it clean. The period also drops a bit, but it's still well-formed.
The best bet on offer is that Tuesday the 18th of August at Dondra. A proper, powerful, clean SSW groundswell. It's a big one, so know your limits. If you're not up for that, the Sunday the 9th of August is a very solid, more manageable option.
Rusty out.

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.
