Muddy fields, cool temps and overcast skies meant fest-goers were wearing sleeves and boots, rather than the usual shorts and T-shirts.
Temperatures struggled to get above 60 degrees through the day, though the official forecast called for a possible high of 71.
The weather for Saturday and Sunday is expected to be picture-perfect, with no chance of rain, lower humidity, and highs in the low 70s.
