The Medusa Festival in the town of Cullera near Valencia was hit at 4: 18 a.m. local time due to a strong wind gust, they said.
Early Saturday morning festival management announced that the festival had been suspended.
The festival organization suspends its activities on Instagram because of the inclement weather in the early hours of Aug. 13, 2022, and with the aim of ensuring the security of the concert-goers, workers and artists gathered at the Medusa Festival.
The festival site is cleared as a preventative measure with the aim of facilitating the work of the emergency and security services at the Medusa Festiva, it added.
Videos posted on social media early Saturday showed strong winds and structures falling from the stage as large crowds of festival attendees were evacuated. The Valencia section of Spain's national weather service AEMET said on Twitter that warm breezes were producing very strong gusts of wind and abrupt increases in temperature. The temperature was a blistering 40.5 Celsius 104.9 degrees Fahrenheit at the Alicante-Elche airport, just south of the concert site, on the Mediterranean coast with winds of 82 kilometers around 50 miles per hour. Temperatures have been soaring across Europe, with droughts declared in several parts of England and wildfires in France.
