The Lowdown
Alright folks, Rusty here with a look at what Bundoran has in store for us over the next couple of weeks. Gotta be straight with you, the start of this run is pretty grim. We’ve got some messy swell early on, but there are a few windows where things clean up, and a couple of bigger swells later that look promising, even if they come with a bit of wind.
Right now, the water is sitting at a very unusual 63°, which is much warmer than normal for this time of year.
We’re looking at a big gap of poor conditions to start. The first real hope comes on Wednesday, 2nd September, in the morning. It’s a tiny little pulse of 2ft from the west, but with a light southeast offshore breeze, it’ll be glassy and clean. The energy is weak (57), so don’t expect much push, but it’s the first surfable window after a flat spell.
Then we skip ahead to the real standout. Saturday morning, 5th September, brings a solid 6ft swell from the west-northwest with a decent 11-second period. That’s a proper groundswell folks, and with light south-southwest winds keeping it cross-offshore and clean, Bundoran should be reeling off some great shape. The combined energy is solid (672), and it’s not too big for a good intermediate session. This is easily the best on offer.
Later that afternoon the swell drops to 5ft, still clean, but the energy backs off a bit.
Looking further ahead, Tuesday morning, 8th September, has some potential with a 4ft west-northwest swell and a moderate offshore breeze from the south-southeast. The energy is moderate (235) and conditions should be clean. It’s a decent window.
The second week gets bigger but more gnarly. By Monday morning, 14th September, we’re looking at a 7ft groundswell from the west with a 13-second period. That’s a lot of water, with very strong energy (1558). The winds are cross-off from the south-southwest, keeping it clean, but this is big enough to be expert territory. The following days are even bigger, hitting 12ft, but the winds get sketchy and it’s a real handful. If you’re a charger, keep an eye on that Monday the 14th, but it’s a long way out so treat it as promising but not locked in.
So, bottom line: suffer through the early week mess, get stoked for Saturday the 5th, and maybe keep an eye on that big one mid-month.

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.
