Organisers of the Brazilian leg of Taylor Swift’s “The Eras Tour” acknowledged on Thursday they could have taken more measures to help fans cope with the extreme heat they faced last week in Rio de Janeiro.

T4F’s (SHOW3.SA) statement follows a last-minute postponement of Swift’s performance last Saturday in Rio due to record-breaking heat after a fan died in the sweltering conditions a day earlier.

“We recognise we could have taken some alternative actions in addition to all the others we have done,” T4F Chief Executive Serafim Abreu said in a video posted on social media.

On the first night of Swift’s tour in Rio last Friday, 23-year-old Ana Clara Benevides fell ill and later died in a hospital. The extreme conditions led the U.S. pop star to postpone her concert the following day, just two hours before she was to go on stage.

The heat index, which combines temperature and humidity, hit 59.3 degrees Celsius (138.7 degrees Fahrenheit) in Rio on Friday, before peaking at a record 59.7 degrees Celsius (139.5) on Saturday.

The extreme conditions led the federal government to order T4F to ensure water access at all of Swift’s concerts in Brazil and issue a directive allowing water bottles to be brought into all concerts from now on.
