The Lowdown
Alright folks, Rusty here, looking at the stretch ahead for Bundoran. It’s a bit of a mixed bag, to be honest. We’re looking at a lot of small, ordinary days before things get properly interesting, so we’ll have to be patient.
Right now, it’s pretty flat. We’ve got tiny waves and clean conditions, but nothing with any push. The water is sitting at a touch warmer than normal for this time of year, so that’s a small win while we wait.
The first week of this outlook is mostly about small, weak surf. There’s a little bump around the 13th, but it’s still only knee-high with weak energy (100). The wind is mostly cross-off or light, though, keeping things clean even if there is nothing to ride.
The 14th and 15th see the swell pick up slightly, but the wind turns cross-onshore and it gets choppy. That’s a write-off as far as I’m concerned. Even though we’re seeing more energy (133), it’s messy and not worth your time. We get a little respite on the morning of the 16th with clean conditions, but the swell is dropping back down again. This quiet, ordinary pattern is going to hang around until the 18th.
Now, listen up, because this is where it gets interesting. On the morning of the 19th, things are going to change in a big way. We’ve got a proper swell event on the cards. The models are showing a jump to a 16ft swell from the west-northwest with a long 13-second period, and the energy is through the roof (7837). This is a serious groundswell. This is a big, powerful swell, well over the 8ft mark, so it’s strictly for the experts. This kind of long-period swell can be tricky at beach breaks, but at a reef setup like Bundoran, it should focus the energy nicely. The downside is the wind is forecast to be straight onshore, which will put a bit of texture on it. Still, this is the standout of the entire period, a proper beast. The afternoon will still have plenty of power, but it might be a bit less clean.
The following day, the 20th, is still big but dropping. 8ft from the west-northwest with a 11-second period. It’s still a solid swell, but lighter winds make it a more manageable prospect for the expert crew. It’s not the same quality as the peak of the swell, though.
The rest of the period fades back into a similar pattern of onshore winds and average surf. Don’t get too excited about it. We do have a little glimmer on the morning of the 22nd with cleaner conditions and a 5ft west swell, but it’s nothing compared to that 19th.
So, to sum it up: the first week and a half is a waiting game, but the morning of the 19th is the one. That’s the standout. It’s a serious, powerful swell for the experts. Mark it in your calendar and keep your fingers crossed for that wind to ease off.
Rusty, signing off.

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.
