Weather forecast for the 2026 Cork City Marathon


As we get nearer to the 2026 Cork City Marathon, the weather forecast is looking pretty good. While spectators might like to see blue skies and sunshine, runners want to see cool overcast conditions.

As the image shows above, it should be mostly dry with the risk of an occasional shower. The temperature should be around the mid-teens which is ideal considering that it's the last day of May and it could just be as easily be in the mid-twenties.

There's a breeze from the south-west but nothing significant.

If you're doing the marathon, half or 10k, make sure not to overdress. Think singlet or short sleeve top. If you feel a bit cold at the start line then that's about right. Once the race starts, you'll be trying to stay cool after a few kms.
