The Lowdown
G’day, Rusty here. Lookin’ at the charts for Sri Lanka over the next couple of weeks, and I gotta be honest with ya – it’s a tough stretch. The swell is there, but it’s been hammered by cross-onshore winds just about every day, messin’ up the surface. The water’s sittin’ at a warm 79°, which is pretty much spot on for this time of year, so at least you won’t be shiverin’ while you’re waitin’ for a clean one.
We kick off on Thursday, 13th August. The swell is a solid 8ft from the south, with a long 17-second period – that’s proper groundswell energy, with a combined energy of 3463 (moderate to strong). But the wind is a cross-on from the ESE at 15 mph, makin’ conditions poor and choppy. The swell is over 8ft, so this is expert territory only, and with the wind ruining it, it’s a no-go for a paddle. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
Friday, 14th August, the swell drops a little to 7ft from the SSW, still with a long 16-second period. The wind stays cross-onshore from the SE at 9 mph, so it’s a gentler breeze, and the chop is a bit less angry. Still, the surf is only marginal, with a combined energy of 2496. It’s not gonna be a classic.
Saturday, 15th August, we see a bit of improvement. The swell is 7ft from the SSW, with a 17-second period, and the combined energy is up to 2755. The wind is still cross-on from the ESE at 9 mph, but the conditions are described as “fairly choppy” rather than full-on messy. This is the best of a mediocre bunch early on – not perfect, but if you’re desperate, you might find a few waves.
Sunday, 16th August, the swell starts to ease to 7ft, and the energy drops to 1954. The wind is still cross-on from the SE at 9 mph. The quality is still marginal, and the tide might be a factor.
From Monday, 17th August, through to Tuesday, 25th August, it’s a real struggle. The swell varies between 4ft and 8ft, but the wind is always cross-on or onshore, and the conditions are consistently poor or marginal. The combined energy dips as low as 800, and the scores are all zeros or ones. There’s a lot of wind and chop, making it hard to find a clean wave. The Wednesday, 19th August, has a nice 8ft south-southwest swell with an 18-second period and energy of 3305, but it’s still cross-on, so it’s wasted.
The best shot in this whole 16-day window is on Saturday, 22nd August. The swell is 7ft from the SSW, with a 16-second period, and the combined energy is 2636. In the morning, the wind is actually onshore, not cross-on, from the ESE at 15 mph. That’s a bit of a gamble – it’s still windy, but if the wind holds straight onshore, it might clean up the face a little. The crowds are possible at this spot, but with conditions like this, it’ll be quiet. The swell is over 5ft, so it’s not for beginners, but experts might find a few if the wind plays ball.
After that, the last week of August into early September sees the swell drop off, with heights from 3ft to 7ft, and the wind never lets up. The combined energy stays weak to moderate, and the conditions are poor or marginal. It’s a long gap of poor surf, really from the 21st onward.
So, lookin’ at the whole picture, the standout is Saturday, 22nd August, with the morning session offerin’ the best chance of a clean-ish wave, but it’s still a gamble. The rest of the period is a write-off, with cross-onshore winds ruinin’ the potential. The swell is there, but the wind is the enemy. Keep an eye on the forecasts, but for now, I’d say it’s more of a beach day than a surf day.
Rusty.

Information about the Sri Lanka Surf forecast
The above surf forecast table for Sri Lanka provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sri Lanka can be found by selecting the local surf guide option on the grey menu. Our Sri Lanka 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 (Sri Lanka) 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 Sri Lanka 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.
Sri Lanka is 10 km (6 miles) from the city of Kuta. If you plan a holiday in The Bukit - Bali, look for hotels and other accommodation in Kuta. Kuta has rooms for a wide range of budgets as well as car hire and transport links.
