The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Dondra over the next couple of weeks.

We’ve got a long run of surf coming, but I gotta be straight with you—the quality is a bit of a mixed bag. This is a reef setup that’s got a good exposure to the SW, and it’s inconsistent, so don’t expect it to be pumping every session. The water temp is sitting at a warm 81°, about average for the time of year, so you can get away with a spring suit or just boardshorts if you’re tough.

The action kicks off proper on Tuesday the 18th of August. The morning shows a solid 8ft swell out of the SSW with a very long period of 19 seconds. That’s some serious groundswell energy (4254), but because it’s a reef break with that long period, it should set up nicely. Wind is a 16 mph cross-off from the W, keeping things clean. This is your best early call—it’s got size, direction, and clean conditions. Afternoon holds similar at 8ft and 12 mph cross-off. This is a big wave for this spot, so it’s one for the experienced crew.

Wednesday the 19th drops a little to 7ft in the morning, but the wind goes cross-shore, putting a bit of a chop on it. The afternoon cleans up again with 6ft and cross-off wind. Still decent.

Thursday the 20th starts with 8ft and clean cross-off wind again, but the energy is dropping (2562). The swell sticks around at that 8ft mark in the morning, which is still solid, but it’s a bit less punchy.

By Friday the 21st, we’re down to 5ft, and it keeps easing into the weekend. Saturday the 22nd sees a slight bump back up to 6ft from the S with clean conditions. Not a standout, but rideable.

The following week, from Sunday the 23rd through to the end of August, it’s mostly small surf, between 3ft and 5ft, with the occasional clean window. Energy drops well below 1000 on some days, meaning weak, small waves. The wind stays consistent from the W at 12-16 mph, mostly cross-off, so at least it’s tidy. But honestly, it’s a pretty lackluster stretch.

Now, looking way ahead to the end of August and into September, things start to look a bit more interesting again. On the 29th of August (Saturday), we see a solid SSW groundswell building to 5ft with a 17-second period and clean cross-off wind. That one has some promise, but it’s still a week and a half away, so don’t book your flights just yet.

The real late bloomer looks like Monday the 31st of August. The afternoon session is showing a 7ft SSW groundswell with an 18-second period and 16 mph cross-off wind—practically perfect for this reef. The energy is strong (3197). That’s shaping up to be your best option in the whole window, but it’s a long-range call, so treat it as a hopeful, not a certainty. Tuesday the 1st of September keeps that energy going with 8ft and clean wind, but again, it’s two weeks out.

So, the standout to me is Tuesday the 18th of August, morning session: 8ft, clean, long period groundswell. It’s the most reliable good call early on. The other real quality option is Monday the 31st of August afternoon, but that’s a waiting game. For the rest of the time, it’s mostly smedium waves with occasional clean windows. Keep an eye on the sky, and if the longer-range stuff holds, we could be in for a treat.

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.
