On this date in 1872, the temperature climbed to 90 or higher for the 18th straight day, tied with 1999 for the third longest such streak on record. The longest streaks of 21 days occurred in 1988 and 1980, and the second longest streak of 20 days occurred in 2020.
And on this day in 1954, the temperature climbed to 100 for the second day in a row. “Three persons collapsed and died … as the Washington area sweltered through its second straight day of record-breaking 100-degree heat,” the front page of The Washington Post reported.
Although the high of 100 on July 14, 1954, was a record at the time, it was topped on this date in 2024 when the mercury soared to 101 — the first of four straight days in the triple digits.
