The Lowdown
Right, grab a coffee, let’s get into it.
The forecast is a bit of a mixed bag – we’ve got some serious swell potential, but the wind is going to be the main character for a lot of the run. There’s a proper stormy period to start, so we’ll have to wait for that to clear before Bundoran (Ireland) really turns it on.
The first week is a write-off for the most part. Friday the 4th sees a big 13ft W swell from a stormy westerly direction, but it’s hammered by a strong cross-onshore wind at 28 mph. The water is noticeably warmer than normal at 62°, but the combined energy is a massive 4217, so we’re talking about a raw, powerful, churning ocean. That’s for experts only if they’re feeling brave, but the conditions are honestly poor. The weekend of the 5th and 6th is a bit smaller, with a 5ft cross-off swell on Saturday afternoon giving a glimmer of hope, but it’s fairly weak at 378. The following week is mostly a washout with strong winds and messy cross-chop; it’s a proper test of patience.
The real standout, and the one to circle on the calendar, is Friday the 18th of September. This is the best window we’ve got. The swell drops back to a solid 8ft from the WNW, but the combined energy is still a solid 1326, so there’s plenty of grunt. The wind shifts to a light, offshore breeze from the ESE early on, and then in the afternoon, we get absolute glassy conditions. That’s a massive positive. This is a reef break, and with a 10-second period, it’s going to hold up well, giving clean, powerful lines. This is the one for experienced surfers only – it’s not a beginner’s wave. There’s a chance of crowds here, so get in early.
Saturday the 19th looks small again, finishing the run with a whimper. So, the advice is: suffer through the stormy, windy first week, and get ready for that Friday the 18th. It’s a long way off, but it looks like a cracker.

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.
