I'm hopeful for a positive meteorological outcome & know that I've still had great fun in my muddy / wet years ('07 & '16).
That said, I can't help my innate britishness and find myself thinking about the "80 days of rain" event that afflicted the country in the latest Year & Years episode.
Whilst that's unlikely (yes?) for this year, climate change could well deliver summers like that in the not-too-distant future - if we reach that point could that spell the end of the festival season as we know it?
If there was greater likelihood of deluge every year who would still commit to their favourite open air festivals year after year?
