It's the middle of summer. It's a long weekend. It's a music festival. It's Ireland. And... it's raining.

Yes, the revellers down at Tullamore have had a rather wet start to the weekend. Nothing says 'outdoor event in Ireland' quite like trying to put up a tent during a downpour.

There's a full line-up of great bands playing the weekend - including Gruff Rhys, Tvvins, Funeral Suits and Ghost Estates - but Twitter discussion has so far been been dominated by talk of the weather.

Here's a selection of comments from the festival so far. It's fair to say there's a bit of a trend:

Will it EVER stop raining at #Castlepalooza? It's been 15 hours and its getting more and more torrential.

If I'm not sick in the morning it'll actually be a miracle. Rolling in the mud in the rain all night being a swamp creature #castlepalooza

There's always a brightside, though:

It's a good thing there's mega posh Castle to chill out in. There's yoga at 1pm. Sorted! #castlepalooza
