Glastonbury 2005 Flood

The worst weather-induced disaster in UK music history, Glastonbury 2005 is defined by relentless rainfall that turned Worthy Farm into a knee-deep mud hellscape, overwhelming 150,000 festivalgoers. Organizers deployed 1,000 extra pumps to remove standing water, yet conditions still caused collapsed tents, flooded stages, and sanitation failures that cost the local economy an estimated £80 million during the ensuing fallow year. The flood directly forced a permanent shift in emergency planning, mandating a 100-person weather team and drainage upgrades.
