The Lowdown
Alright mates, Rusty here. Let’s have a look.
Got to level with you – this forecast is a tough nut to crack. From Friday the 31st of July right through to Saturday the 8th of August, the surf is either flat or blown to bits. That’s over a week of small, messy, cross-onshore junk. The water’s about 62°F, which is a touch warmer than normal for the time of year, so at least you’re not freezing while you’re staring at nada.
The first real hope shows up on Sunday the 9th of August. The morning has a little pulse – 3ft from the WNW with a short 7-second period. The combined energy is only 116 (moderate), and while the wind is light offshore from the ESE, it’s just not enough to get excited about.
But Sunday afternoon is where it’s at. Swell picks up to 5ft from the WNW, period stretches to 9 seconds, and the energy hits 322 (moderate). The wind swings light S, giving us a clean, cross-off breeze. This is the only genuine standout in the whole 16-day window. Bundoran is a reef break, so with that longer period and the right direction, it could turn on. It’s a fairly consistent spot, and the offshore wind from the SE means clean, glassy lines. Crowds are possible, so get in early. The water’s still a touch warmer than normal, so you’ll be comfortable.
After that, Monday the 10th drops back to 3ft, and the rest of the run is just small, weak dribble. By the 15th of August, there’s a little bump back to 4ft and 4ft, but the wind is onshore or cross-onshore, and the period is short – 6 or 7 seconds. That’s choppy, weak junk with energy between 104 and 186. Not worth suiting up.
Bottom line: if you want a wave, aim for Sunday afternoon, the 9th of August. That’s your one real shot. The rest of the forecast is a long, flat wait.
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.
