April in Tucson was warmer than normal this year, hitting both 95 degrees and 100 degrees for the first times in 2023.
April 2023 was the 14th warmest April on record with an average temperature of 70 degrees, the National Weather Service says. Typically, April has an average temperature of 68 degrees.
The average high temperature of the month was 86 degrees, which is around 4 degrees more than the normal high. The average low temperature was 53 degrees, the normal low typically seen in April.
Within the span of two days, Tucson recorded the first high of every temperature in the 90s this year. On April 10th, Tucson hit 95 degrees for the first time and on the 11th, it hit 99 degrees.
The first 100-degree day of this year was April 30th, making it the seventh earliest first 100-degree occurrence here in records kept since 1897. Normally, Tucson sees about 68 days a year that hit triple-digit temperatures, the weather service says.
Aside from the hotter temperatures, April 2023 was the third straight April with no measurable rain at Tucson International Airport. April usually sees around 0.24 inch of rain.
It was also the first time on Tucson record that an April recorded a freezing low temperature and a triple-digit high. The other times this happened were in October 1929 and October 2020.
The airport recorded the last freeze date of the 2022-23 cool season on April 5th when it hit 32 degrees. This is the latest last freeze date since 1936, the weather service says.
And, for one more twist, the day after Tucson’s first 100-degree day of 2023, the high dropped into the 80s (88) the next day. That’s only the second time in local records that’s happened; 2006 was the other.
Highs in the 80s are expected for the rest of this week.
