The Lowdown
Alright, Rusty here, let’s talk about what’s on offer for Bundoran.
Right now, the forecast starts with a bit of a slow go. We’ve got some small, weak swell early on, but the winds aren’t doing us any favours. It’s not until the afternoon of Friday the 11th that we see a glimmer of hope. The swell picks up to a waist-high 4.3ft from the WNW with a clean 9-second period. The wind goes light cross-offshore, tidying things up nicely. It’s not a classic, but it’s the first clean session on the board with a moderate 276 combined swell energy.
Saturday the 12th brings a jump in size – we’re talking a solid 6.6ft from the W with a 12-second period, giving us some proper groundswell energy (1048). The trouble is, the morning is blown out by a moderate cross-shore wind, and the afternoon is choppy with cross-onshore. This one’s for the experienced crowd only if you can find a window.
The standout window looks to be the morning of Friday the 18th. That’s over a week out, so hold fire on the plans, but it’s a beauty on paper. We’ve got 6.6ft of WNW groundswell with a 12-second period (1216 combined energy) and clean cross-offshore winds from the SSE. This is proper, powerful stuff – best for reef, point, or river mouth as the long period can make beachbreaks weird. This one’s for experienced surfers only, as the size and energy are next level. The break is fairly consistent and crowds are possible, so don’t be late.
A week later, early on Friday the 25th, we get another crack with a clean 5.2ft from the WNW and light cross-offshore winds (603 combined energy). It’s a more manageable size, good for intermediates, and the wind will have it looking clean.
Water temp is 61°, which is a touch warmer than normal for this time of year – a nice little bonus for the first session.
Overall, Bundoran has a few good windows, but Friday the 18th morning is the one to circle. Be patient early on, and don’t sleep on that Friday the 25th morning session either.

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.
