The Lowdown
Alright folks, Rusty here. We're looking at the Bundoran (reef) forecast, and it's a bit of a mixed bag over the next couple of weeks. The water at Bundoran is sitting at 63°, which is a solid 3.8° warmer than usual for this time of year – definitely feels like a warm bath compared to normal.
Right now, we're in a bit of a quiet spell. The surf is small and weak, with a combined swell energy of just 70, and a cross-shore wind is making a mess of things. That trend of poor surf conditions with lumpy, choppy waves and fresh cross-onshore winds is going to stick around for a good long while. We're looking at a rough patch from Monday the 17th all the way through until Monday the 24th of August. It's not going to be worth paddling out for most of that week.
The first real glimmer of hope shows up on Tuesday, the 25th of August. The morning is looking promising, with a 3.9ft W swell, a period of 10 seconds, and light cross-offshore winds from the south. It'll be clean, and the combined swell energy climbs to a solid 260. The wind is light and the conditions should be clean. It’s not massive, but it’s the best we've seen in days.
The biggest standout, however, is a long-range call for Tuesday, the 1st of September. The forecast shows a proper 5.6ft groundswell from the WNW with a very long period of 14 seconds and a combined energy reading of 1223. The wind is forecast to be light and cross-offshore from the south, setting up clean conditions. It's a long way out, so don't set your watch by it, but for experienced surfers, this has the potential to be the session of the window. The long period will mean plenty of push and nice shaped waves on the reef, but the sets will be widely spaced.
After that, we get another windy and messy run towards the end of the forecast.
Stay tuned.

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.
