Dondra Surf Forecast and Surf Report

G’day surfers, Rusty here. Let’s talk about what’s on offer at Dondra (Sri Lanka). The water is sitting at a warm 83°F, which is about average for this time of year – no big anomaly to report.

We kick things off on Thursday afternoon, 27 August, but honestly, the surf is pretty average. Waves around 5ft from the SSW, with a solid 17-second groundswell – that long period means it’ll be better at a reef setup like Dondra, but it also brings that wait between sets. Wind is a cross-off from the W at 12 mph, keeping things looking clean. The combined energy is moderate (1970), but the forecast warns of “marginal” conditions, so don’t expect perfection.

Friday 28 August is a mixed bag. The morning has a cross-shore chop with 16 mph WSW wind, making it a bit lumpy – not ideal. Swell holds at 5-5ft from the SSW, with periods dropping to 14-15 seconds. Afternoon clears up nicely: cross-off wind returns, and it’s clean again, but still “marginal.”

Saturday 29 August sees the swell drop a touch to 4-4ft, still from the SSW, with a 13-second period. Winds stay cross-off at 16 mph, but energy is weaker (649-767), and the surf quality is rated low.

Through Sunday 30 August and Monday 31 August, we’ve got a bit of a build. On Monday morning, the swell pushes up to 8ft from the SSW with a long 18-second period. That’s a solid groundswell – energy jumps to 3300 – but at this size and period, it’s getting into expert territory. Wind is clean cross-off from the W at 16 mph, so the reef should handle it nicely, but be aware: this spot is “inconsistent” and “sometimes” crowded, so you might have to wait for sets, and you’ll have some company.

The Monday afternoon holds at 7ft. This looks like the standout window – the biggest, most powerful swell of the whole stretch, with clean winds. If you’re experienced, aim for Monday.

From Tuesday 1 September into the first week of September, the swell slowly backs off from 7ft down to 5ft, with periods shortening from 16 seconds to 13-14 seconds. Winds remain cross-off or cross, mostly from the W or WSW at 12-16 mph. Surf quality stays “marginal” on the best days, with some mornings sporting a cross-chop.

By Friday 4 September, the swell is down around 5ft from the S with a short 11-second period. Energy is dropping (654-808). Not much to get excited about.

The second week, from 5 September onward, gets weaker. Swell sizes drop under 4ft through to 3ft by 6 September, period down to 10 seconds. Winds are cross-off or cross, but the energy is low (429-540). 7 September picks up a little to 5ft from the S, but still not firing.

8-9 September is the worst of it – swell down to 1-3ft from the SSE/SW, with periods all over the place. The 9th has a 2ft swell with a 20-second period, but that’s barely a bump.

We do see a late uptick on 10-11 September: swell climbs back to 5-6ft from the SSW with 16-18-second period, and clean cross-off winds at 16 mph. Energy hits 1160-1620 – moderate but promising. This is the second standout: Thursday 10 and Friday 11 September offer the best clean, long-period groundswell after the Monday peak.

A couple of notes: Dondra is a reef break that sometimes has crowds, and it’s “inconsistent” – so don’t expect endless waves. The best recommendation for this whole period is Monday 31 August for the biggest swell (8ft-7ft, SSW, long period, clean winds) and then Thursday 10 / Friday 11 September for a solid, well-shaped runner-up with good energy.

Stay sharp, and don’t sleep on that Monday session – but bring your A-game.

Rusty.
