As thousands of people marched in D.C. on Saturday to demand climate change action, the sweltering heat broke and tied multiple records for April 29.

With a high of 89 degrees, Dulles Airport broke its record high of 87 degrees set in 1974 and again in 1996, according to the National Weather Service.

The temperature at Ronald Reagan Airport reached 91 degrees, which ties the hottest day on record for D.C. set in 1974, according to the National Weather Service. And BWI Airport hit 90 degrees, also tying a 1974 record, the Capital Weather Gang reports.

CWG also points out that morning temperatures on Saturday didn’t dip below 70 degrees, which has never happened in the month of April, “and in a lot of ways that’s more significant than a record high.”

Saturday was also the first time we hit the 90s mark this year. According to NBC Washington meteorologist Amelia Draper, temperatures were 20 degrees above normal—the region usually doesn’t get that kind of heat until the middle of May.

Washingtonians got a taste of unseasonably warm temperatures in February as well, which saw multiple record-breaking days.
