I write this sitting in a service station somewhere in southern England as rain lashes the car park and those smokers still brave enough to risk a puff get drenched. The weather is one of those 'big' issues at Glastonbury, along with the state of the toilets, ability to find your tent and - oh all right - the bands.
The BBC forecast for Glastonbury town is rain-or-hint-of-rain every day from now right up until Wednesday, at which point we are promised "sunny intervals". What comes after that is almost anyone's guess as weather forecasting is a notoriously difficult art / science over just a five-day period; over ten it's almost impossible. So a drizzle during the proceedings is almost to be expected.
Rain isn't always unwelcome at Glastonbury Festival either. During one particularly scorching year we had a little shower which cooled things down a little, brought the dust under control and provided just enough moisture for comfort without bringing on the dreaded mud.
It's always better to be prepared though, because after all there isn't an awful lot you can do to control the weather. Michael Evis tried in 2005 with some bizarre contraption that was meant to blow away the clouds. And that didn't work very well, as those who had to swim out of their tents on Friday morning will confirm!
Mmm, it's looking a bit brighter now...
