Metro Phoenix's dry summer weather isn't surprising.
However, residents may be shocked to know that there is one day it has never rained — June 11.
Since the National Weather Service began keeping records nearly 130 years ago, Phoenix has only seen trace amounts of rain, meaning the moisture was so light that it was not measurable, according to meteorologist Mark O'Malley. That was in 1991.
There are also two other dates — May 30 and June 16 — where just 0.01 inch of rain has fallen, O'Malley confirmed.
Why is that? It's because June is the driest month in Phoenix. Here's why metro Phoenix sees such dry weather in June and what to expect this week.
June is the driest month for metro Phoenix, O'Malley said. On average, only 0.02 inches of rain falls during the whole month. Most years, including 2023 and 2019, no rain falls during June.
"Just to get rain on any single day is an uncommon occurrence," he said.
This year, an early June storm system dumped more than an inch of rain around the northern reaches of metro Phoenix, hinting at more moisture ahead than the Valley has seen over recent summers.
"The first part of monsoon is not as wet as later in the monsoon," O'Malley said. "You have to pull in a lot more moisture. For Phoenix specifically, we don't start to see thunderstorms due to monsoon until about the beginning of July."

Though monsoon starts on June 15, there is no rain in the forecast, O'Malley said.
"We're looking for seasonably warm conditions with high temperatures in metro Phoenix of 105 to 110 degrees and then getting hotter over the weekend," he said.
Here is the weather forecast for Phoenix Sky Harbor International Airport, the official weather station, according to the weather service:
