PHOENIX — The city of Phoenix on Saturday endured its first day of 110-degree temperatures this year, according to readings by the National Weather Service.
Phoenix Sky Harbor International Airport, which NWS uses for official measurements, reached exactly 110 degrees at around 4:35 p.m.
In 2024, Phoenix saw the most days of 110-degree-plus heat in city history at 70. There were also 143 days of 100-plus temperatures and 21 days in a row of daily heat records from September to October.
Midway through June, Phoenix has seen 25 days of high temperatures in the 100s.
The unofficial low on Saturday was 82 degrees, which NWS said was four ticks above normal for June 14.
NWS had issued an extreme heat warning earlier this week, and added Saturday that the temperature on Father’s Day is expected to be even higher.
Sunday’s forecasted high temperature ranges from 110 to 114 degrees, with a low to be around 80.
Phoenix heat calls for more caution when outside
NWS advised Valley residents to drink water and electrolyte-heavy drinks as the heat wave continues. High consumption of alcohol will not help with hydration, NWS added.
When it is necessary to go outdoors, NWS recommended wearing lightweight clothing and applying sunscreen with an SPF of 30 or higher.
To aid others with heat relief, residents are encouraged to donate water, sunglasses, umbrellas and other resources to a pair of Phoenix shelters, Central Arizona Shelter Services (CASS) and Keys to Change.
