The heat is on in New York City! The temperature in Central Park soared to 91°F on Saturday, marking the city’s first 90°F day of the year.

While readings in the 90s are not uncommon for the Big Apple during the summer months, they typically premiere earlier in the season. On average, the city usually sees its first 90°F day by the end of May.

According to NWS records, the city’s earliest first 90°F day was April 7, 2010, and its latest was July 26, 1877.

For the season as a whole, NYC typically gets an average of 15 days with temperatures reaching 90°F or higher. By month, that usually breaks down as May (1), June (3), July (6), August (4), and September (1). That said, every year is different. The most 90°F days the city experienced was 37 during the sweltering summer of 2010.
