The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Dondra. It’s a mixed bag, but there’s a pulse of proper energy on the horizon if you’re willing to wait.
The outlook kicks off with a real slow start. The first few days from Friday the 17th through to Sunday the 19th are pretty flat and uninspiring, with weak swell around 3ft to 3ft from the SSW. The wind is a steady cross-offshore breeze, which would normally be a plus, but the wave energy is just too low to get excited about. The combined energy values are sitting in the low hundreds (300 to 537), which tells you it’s puny. You’d be fighting for a knee-high dribbler. Honestly, it’s not worth paddling out.
Then we hit Monday the 20th of July, and things start to change. A solid S swell pushes in, with heights climbing to 4ft in the morning and 6ft by the afternoon. That’s a proper step up. The period is a long 16 to 18 seconds, which is classic groundswell. The combined energy jumps to 1777, and that’s a moderate amount of grunt. The wind is still cross-offshore from the W at 12-16 mph, so the surface will be clean. Dondra is a reef break, and that long-period swell will wrap in nicely, offering up some clean, lined-up waves. This is your best bet for the first week. The water temp is about average for the time of year, nothing weird, just your usual tropical warmth.
The surf quality on Monday is decent, but the scores are just okay – it’s a bit of a marginal window with the tide, so pick your session. It’s enough to get a few good ones. The crowd factor is “sometimes” at Dondra, so you might have a few others out, but it won’t be a circus.
Tuesday the 21st holds onto similar size, around 5ft to 5ft from the S, but the wind shifts to a cross-shore from the WSW, and you’ll start to see a bit of chop on the face. Still rideable, but not as clean as Monday. From Wednesday onward, the swell drops back into the 2ft to 4ft zone, and the wind stays cross or cross-off, but the energy is weak – those combined energy values fall back to the 300-600 range. It’s marginal at best. You’re looking at a gap of several days with no real standout surf.
Now, if you’re a patient surfer, there’s something brewing way out in the second week. Around Wednesday the 29th of July, you start to see a spike in period. Wednesday afternoon shows a 3ft swell from the SSW with a period of 23 seconds – that’s very long period groundswell, and the combined energy is 1358. Then Thursday the 30th and Friday the 31st of July see the swell size build to 5ft to 6ft from the SSW, with periods of 17 to 19 seconds. The energy values are climbing into the 2000s (strong to very strong). The wind is still cross-offshore from the W at 16-19 mph, so it’ll be clean. This is a long-range promise, so it’s less certain, but it looks like a proper pulse. That long-period swell will be best at this reef, giving you some real power and shape. The only catch is the size hits 6ft, which is still okay for most, but it’s not a beginner wave.
The final day on the 1st of August shows a 10ft swell from the W with a short 8-second period and a combined energy of 2637. That’s a lot of water moving, but the short period means it’ll be a bit of a messy, wind-affected closeout at the reef. That’s expert territory, and honestly, the wind is a fresh breeze at 19 mph, so it’ll be more of a battle than a joy. The setup looks more interesting for kite surfing than paddle surfing by that point.
For the best on offer, aim for Monday the 20th of July. That’s your standout for the first week. For the second week, keep an eye on Thursday the 30th and Friday the 31st of July – that’s the promising long-range pulse, but it’s a future call.
Stay patient, and pick your windows.
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.
