Why is Phoenix so hot in June?

It’s hot in the summer, it’s going to be hot every summer — and there’s nothing we can do about it.

Why is Phoenix so hot?

Three of the four hottest days on record in Phoenix (the all-time high of 122 degrees on June 26, 1990) have occurred in June.

Many factors contribute to the sweltering heat.

1. Location

Arizona is relatively close to the equator and as a result, receives a lot of the sun’s energy.

We’re approaching the summer solstice (June 20), the longest day of the year in the Northern Hemisphere.

Days are longer during the summer months in the Northern Hemisphere and offer more opportunity for things to heat up.

2. Elevation

The Phoenix area is only about 1,000 feet above sea level.

But many of those places are at a higher elevation and therefore cooler.

3. High pressure

There’s a pretty persistent area of high pressure that generally hangs around the Southwest.

Because high pressure often results in clear, dry conditions, it contributes to Phoenix’s extreme heat.

4. The dry heat

June is the driest month of the year in Phoenix, with only .02 of an inch of rain on average.

The dry air contributes to the extreme temperatures before the monsoon.

And the lack of humidity means it takes less energy for the sun to heat up the dry air.

5. Urban heat island

The urban heat island is a term used to describe concrete, asphalt, and buildings in metro areas holding on to heat.

According to the National Weather Service, the average overnight low for Phoenix in June 2016 was 82.1 degrees, which tied the record set in 2015.

Warm nights allowed June 2016 to tie June 2013 for the warmest average temperature on record.

All five of the warmest Junes on record have occurred since 2006.
