The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming down the line for Bundoran.
The next couple of weeks are a real mixed bag, with the first proper standout windows arriving later on. The water is sitting at 60°F right now, which is a touch warmer than average for this time of year, so you might get away with a slightly thinner wetsuit than usual.
The early part of the week is pretty average, to be honest. We’ve got small, ordinary waves and messy cross-off winds that don’t do the place any favours. Tuesday (15th September) brings a jump in size to around 5ft to 5ft, but the cross-onshore wind kills the quality – it’s lumpy and choppy, so not worth paddling out for. Wednesday and Thursday get bigger, with Thursday seeing swell up past 10ft and combined energy hitting 4576 (strong to very strong), but again, strong cross-onshore winds make it a messy, blown-out mess. That’s expert-only territory and even then, not fun.
Friday 18th September afternoon is where things start to turn. The swell drops to a solid 7ft from the WNW with a nice 12-second period, and the wind goes cross-off with a light breeze. The energy is still strong at 1200, and the waves should be clean and well-shaped. That’s a good window for experienced surfers.
Then, Sunday 20th September has some real size again – 10ft from the WNW, long 14-second period, and combined energy over 3000 (very strong wave energy). The wind is only light, so despite being cross-on, the surface will be fairly clean. That’s another big-swell day that will only suit the confident crew.
But the real standout is Monday 21st September morning. You’ve got a clean 6ft WNW swell, 12-second period, light cross-off breeze from the SSW, and excellent conditions for experienced surfers. The energy is strong at 1051, but the wind and period combo should make for some proper waves at Bundoran (a reef break that’s fairly consistent and exposed to the NW swell). Crowds can pop up here sometimes, but on a Monday morning you might have a bit more room.
Wednesday 23rd September morning is another one to keep an eye on – 7ft from the WNW, and glassy conditions with no wind. That’s as clean as it gets. The period is a shorter 8 seconds though, so it might be a bit weaker and less organised than the longer-period swells.
After that, the end of the month drops right off. From Thursday 24th onwards, we’re looking at tiny waves, mostly under 3ft, and while the wind goes offshore or light, the energy is weak (under 100 to low 100s). It’ll be clean but flat – a gap of several days with nothing worth getting excited about.
So, the best of the bunch? Friday 18th September afternoon for clean, solid waves, and Monday 21st September morning for that sweet light wind and good swell. The big Sunday 20th is worth a look if you’ve got the skills for 10ft.
Keep an eye on the forecast, because that Monday session looks like the pick of the run.
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.
