Sure, it’s a dry heat. But this week’s heat wave was just plain hot. Really hot. As in: Phoenix residents needed a record amount of electricity to stay cool. But these were not the hottest days ever. The all-time high temperature in Phoenix was 122 degrees on June 26, 1990. June tends to produce the hottest days of the year, and the highs moderate as monsoon moisture moves into the region, typically in July.
Here are the record-setting numbers, as recorded at Sky Harbor Airport, the official National Weather Service station in Phoenix.
Monday, June 19: 118 degrees, the high, tied the record for the date, set in 2016.
Tuesday, June 20: 119 degrees, the high, shattered the previous record for this date of 116, set in 2016. It tied for the third-warmest day ever in Phoenix.
Wednesday, June 21: 117 degrees, the high, eclipsed the previous record for the date of 115 set in 2008.
Wednesday, June 21: 90 degrees, the morning low, was the warmest for the date, inching out the previous year’s record minimum of 89.
Thursday, June 22: 91 degrees, the morning low, broke the previous record for warmest low on the date — 90 degrees, achieved in 2005.
In North Phoenix, temperatures were a few degrees cooler each day, due to elevation and proximity to the mountains. See the latest North Phoenix weather forecast.
