The Lowdown
Right, folks, Rusty here. Let's take a look at what's on the cards for Bundoran over the next couple of weeks. It’s a bit of a mixed bag, with some real swell but the wind is going to be the main character for a lot of it.
The forecast kicks off with a bit of a wait. That first proper swell comes through on Friday the 4th, but it's arriving with a strong cross-onshore wind, making it messy and hard to handle. We’re looking at a solid 10ft to 12ft of swell from the west, with a period of 12 seconds. The wave energy is pumping, around 4068, but it's a rough one. The water is a warm 62°F, which is much warmer than usual for this time of year.
Saturday the 5th is a bit smaller, but the wind is still not playing nice. We get a 5ft west swell with a 10-second period in the morning, and the wave energy is moderate (562). It’s marginal, but the cross-off wind in the afternoon might clean it up a touch for a quick session. Honestly, the first week is mostly a write-off. The wind is just too strong and onshore or cross-shore for most of it, with a lot of days marked as "poor surf conditions."
The real standout, the only one worth getting excited about, is the morning of Saturday the 12th of September. This is the one. The wind is pure offshore from the ESE, light at 6 mph, with a 8ft swell from the WNW. The period is a very long 13 seconds, so this is proper groundswell. The combined energy is a very strong 1935. This is bone fide excellent surf for experienced surfers. The reefs at Bundoran will be working a treat with that long period, offering up some proper, powerful lines. The afternoon is also clean with an offshore wind and a 6ft swell, so it’s a solid day all around.
After that, it drops off. Sunday the 13th is small, and the wind goes onshore, killing the vibe. There’s a little grumble of a swell on the 15th with glassy conditions in the morning and afternoon, but it’s only 4ft. It’s surfable, but it’s not the same beast as the 12th. The second week is lean, with onshore winds dominating and a few lumps of swell that just don't get the right wind.
So, to wrap it up: the first week is a washout. Don't bother. The second week, you wait for Saturday the 12th. That’s the day. Get your gear ready and be on it early for the best of the offshore winds. It’s a long-range call, but it looks proper.
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.
