The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s on the table for Bundoran.
Straight up, I’ve got to be honest with you: the next week and a half is a bit of a write-off. We’re looking at a long, quiet stretch here. The swell is tiny, the wind is messy, and the conditions are just not cooperating. For the first ten days or so, from Sunday the 16th right through to the end of that week, it’s just poor surf. We’re talking onshore winds, cross-chop, and only a few scraps of energy. The combined energy doesn’t break 100 (37 to 422) for most of that, and even when it does get a little push, the wind spoils it.
Then, we hit a proper flat spell. From around Saturday the 22nd through to Tuesday the 26th, the swell drops right off. Wave heights are down to 0.7 ft to 1 ft, and the energy readings are in the single digits. The waves are just not there. You’d be better off staying home.
Now, here’s a glimmer of hope, but it’s a long way off. The standout window, and really the only time I’d point you to the water, is around Thursday the 27th of August through to Monday the 31st of August. The swell starts to fill in a little, and more importantly, the wind turns in our favour.
For the best of it, keep your eyes on Bundoran itself. The conditions are a bit ordinary, but we get some clean windows. On Thursday afternoon, we’ve got a light SSE breeze blowing offshore, which is a major positive. The swell is small at 2 ft from the WNW, with a period of 9 seconds, and the combined energy is a weak 64. The water is hanging around 62°F, which is a touch warmer than normal for this time of year, so you won’t need the thickest suit.
Friday the 28th morning is a real standout for the glass. It’s dead calm, absolutely glassy. The swell is 2 ft from the west, period 9 seconds, and the energy is 71. It’s not going to blow your mind on size, but the conditions will be perfect. If you’ve got a log, this is your session.
Saturday the 29th morning is also worth a mention. Again, glassy conditions with a 3 ft swell from the WNW, period 7 seconds, and energy at 72. It’s small, but clean.
And then we round it out with Monday the 31st morning. The wind is light and cross-offshore from the south, keeping things clean. The swell is 2 ft from the west, but look at that period – 11 seconds. That’s some proper groundswell energy coming through, with a combined energy of 90. It’ll be a bit inconsistent, with longer lulls between sets, but the shape will be better.
So, the summary? The next week and a half is a write-off, but the very end of August and into the start of September shows a little pulse. The glassy mornings on the 28th and 29th are your best bet for a clean, if small, session. The Monday morning the 31st has the best quality swell. It’s a long-range call, so don’t nail your plans to it, but it’s something to keep an eye on. For now, it’s a waiting game.
Rusty.

Information about the Bundoran Surf forecast
The above surf forecast table for Bundoran provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bundoran can be found by selecting the local surf guide option on the grey menu. Our Bundoran 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 (Bundoran) 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 Bundoran 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.
Bundoran is 20 km (12 miles) from Killybegs. If you plan a holiday in Donegal, look for hotels and other accommodation in Killybegs. Killybegs has rooms for a wide range of budgets as well as car hire and transport links.
