The Lowdown
Alright folks, Rusty here with the lowdown on Bundoran. It’s a bit of a mixed picture. We’ve got some big swell on the charts, but the wind’s going to be the deciding factor. The water temperature is pretty normal for this time of year, so you’ll be alright in a spring suit.
The start of the week is a total washout. Monday and Tuesday have strong onshore winds making a mess of things. Don’t even think about it. Wednesday is still poor. Finally, on Thursday morning, the 10th of September, we get a sniff of something. It’s only 4ft from the west on a 9-second period, but the wind is light and cross-offshore, giving us clean waves. The energy is weak (196). It’s surfable, but that’s about it.
The standout, and I mean the one to circle on your calendar, is the morning of Saturday, the 12th of September. We’ve got a solid 6ft groundswell from the west-northwest with a very long 13-second period, and the energy is building nicely (1230). The wind is light and cross-offshore, so it’s going to be clean. That long period will wrap nicely into this reef. It’s a fairly consistent spot and it can get busy sometimes, so don’t sleep in.
Then on Sunday the 13th of September morning, we get another clean one. A 5ft west-northwest swell, 11-second period, with beautiful light offshore wind from the southeast (463 combined energy). Expect good, clean surf.
Looking into the second week, Tuesday the 15th of September morning is a big one for the experts. We’re talking 8ft from the west-northwest with a long 12-second period and clean conditions. That’s expert territory. The energy is strong (1835).
And then, get ready for this. Saturday the 19th of September is a beast. The morning shows a massive 13ft west swell with a 13-second period, and the combined energy is enormous (5468). This is huge, powerful, and absolutely for experienced surfers only. The wind is cross-shore, so it won’t be perfect, but the raw power is off the charts.
So, the first week is mostly a dud until the 10th. The one to go for is the morning of Saturday the 12th for a clean, long-period groundswell. Sunday the 13th morning is a great backup. The second week has some colossal swells, but only for the brave and the skilled.
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.
