The Lowdown
Alright folks, Rusty here. Let’s be straight with you – Bundoran is having a bit of a rough patch to kick off this outlook. The first week and a half is pretty grim, with barely a ripple worth paddling for. From now until around the 24th of July, we’re looking at tiny, weak, and mostly onshore wind-affected surf. Most days you’ll see waves around 1ft to 2ft, with very short, weak periods of 5 to 8 seconds. The combined swell energy is mostly in the low double digits (28 to 45), which is barely a tickle. It’s not a great time to be a surfer around here. The water temperature is a notable 64°F – that’s a whopping 6°F warmer than usual for this time of year, which is very unusual. It’s like the ocean skipped a season.
The first real glimmer of hope shows up on the morning of Friday the 25th of July. We’ve got a clean 5ft swell from the WNW, with a 10-second period and glassy conditions. The combined energy jumps to 358 (moderate wave energy). That’s the best we’ve seen in a long time. The wind is dead calm, so it’ll be clean. This is the standout session for the whole outlook. The Saturday morning of the 26th of July is also looking good – another 5ft from the WNW, glassy, with a combined energy of 270. It’s not huge, but it’s clean and rideable.
Things get a bit more serious from the 27th of July, but the wind is the problem. We see a 7ft WNW swell (11-second period) on Monday the 27th morning, with a combined energy of 916 (strong wave energy), but it’s onshore. The wind is 6 mph from the NW, which will mess up the shape. The 29th of July sees a 7ft swell from the W (10-second period) with a combined energy of 988 (strong wave energy), but again, onshore winds. The 30th of July morning has the biggest swell of the period – 8ft from the WNW, 10-second period, and a combined energy of 1161 (very strong wave energy). But it’s onshore wind from the NNW. This is big, powerful, and messy. For a reef break like Bundoran, that’s only for experts, and even then, the wind is going to make it ugly. A 7ft swell on the 27th is also too big for beginners.
Honestly, the best bet is to wait for the 25th of July (Friday) morning. It’s a clean, moderate swell with glassy conditions and a nice WNW direction. Don’t get your hopes up for the rest of it.
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.
