The Lowdown
### Imperial
Alright, let’s talk about Bundoran in feet and miles per hour. The first few days are just a bust. Thursday the 10th through the weekend, forget it. The swell is tiny and weak, with a combined energy of only 69, and the wind is all over the place, mostly side or onshore. You’re looking at poor surf conditions and a lot of chop. The water is 61°F, which is much warmer than usual for this time of year, but that doesn’t help the waves.
Saturday the 12th has a little more size, with swell around 6ft, but the wind is side-shore and the energy is only moderate (963). It’s marginal at best. Sunday the 13th drops back to about 4ft with a light onshore breeze, so it’s not clean. The whole first week is a dud. The wind just never lines up for Bundoran to do its thing.
Now, the real news is the second week. The absolute standout is Monday the 21st of September. That morning we’ve got a clean 6ft swell from the WNW with a light cross-offshore breeze from the south at only 6 mph. The wind will be light and clean, making for some really nice, lined-up waves. The energy is strong (694). Then Monday afternoon gets even better. The swell bumps up to 8ft from the west, with a period of 11 seconds, and the wind swings to a light offshore from the SE at 9 mph. That’s the kind of combo that makes Bundoran’s reef fire. The energy is very strong (1565). This is the one. It’s going to be glassy and clean with plenty of power. Just remember, this spot can get crowded sometimes, so get there early.
The rest of the second week is a letdown. Tuesday the 22nd has a massive 10ft swell, but it’s onshore and messy, so that’s for experts only and even then, it’s not great. The following days are a mix of onshore and messy conditions, with a few cleaner moments, but nothing touches that Monday.
So, bottom line: the first week is a washout. The second week has one absolute cracker of a day on Monday the 21st. That’s your window.

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.
