The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Bundoran over the next couple of weeks. It’s a bit of a mixed bag, so let’s get into it.
First off, we’re starting this Sunday the 13th with a little pulse. Bundoran (a reef setup that’s fairly consistent and exposed to the north-west) is seeing a 4ft groundswell from the WNW with a 11-second period and glassy conditions – that’s about as good as it gets for a clean start. The wave energy is moderate (279), and with the light SSE air, it should be a proper session for intermediate surfers. Keep in mind it can get busy here sometimes, but early Sunday morning is the time to be in the water.
Sunday afternoon drops off a bit, with smaller 3ft swell and a light cross-off breeze, still rideable but not as good. Then from Monday through to Thursday morning, things get pretty ordinary. We’re looking at onshore winds, building swell, and generally poor conditions – a real write-off for a few days. The swell energy picks up, but the wind just ruins it.
Thursday afternoon the 17th brings a solid 10ft groundswell from the WNW with a very long 16-second period. That’s a proper pulse, with combined energy reading 4026 – that’s strong. But the wind is a fresh cross-onshore, making it lumpy and messy. That’s for experts only, and even then, it’s not going to be pretty. It’s a no-go for paddle surfing; might be more of a kite session.
Friday the 18th is where we see a bit of a turnaround. Morning brings a clean 8ft swell from the W with a 13-second period. The wind is cross-off from the SW, and the energy is strong (2288). It’s still big, but the conditions are cleaner. The afternoon holds at 7ft with similar conditions. This is the first real standout for decent surf, but it’s still solid – more for the experienced crew.
Saturday the 19th is another write-off with strong onshore winds and 12ft swell – messy and dangerous.
Now, here’s where it gets interesting. Sunday the 20th, the swell hangs around 10ft from the WNW, with a 14-second period and cross-off winds. It’s big, but it’s clean, and the energy is very strong (3380). This is a serious window for experienced surfers. Monday the 21st, the wind swings back onshore and ruins it again.
Tuesday the 22nd, we see the swell drop to 6ft from the WNW, with a 12-second period and cross-off winds. It’s clean and much more manageable, with moderate energy (887). That’s a good session for intermediates, and the best bet for a solid paddle.
The big standout in the second week is Thursday the 24th. Morning shows a 12ft groundswell from the WNW, 13-second period, cross-off winds and very strong energy (3829). The afternoon is even bigger at 13ft from the WNW with a 14-second period and cross-off winds, energy at 5182. This is a serious swell. For experts only, and with that long period, it’ll be lining up beautifully on the reef at Bundoran, but it’s a handful.
After that, Friday and Saturday see the wind turning onshore again, making things messy, though the swell stays solid. Sunday the 27th, the swell drops to 7ft from the W, 12-second period, but it’s onshore, so not great. The outlook finishes on Monday the 28th with a tiny 2ft glassy morning – barely surfable.
So, the standout sessions are Sunday morning the 13th for a clean, fun session, Friday the 18th for a solid clean swell, and Thursday the 24th for the big, clean, expert-level groundswell.
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.
