I recall listening to an NPR story about the increasing overnight temperatures, particularly due to concrete//cement//pavement. One man interviewed speculated that within his lifetime he'd experience overnight Phoenix temperatures of at least 100F. This aired around roughly 15 years ago, give or take.
- cheald 7y agoI'd be willing to guess that the vast majority of increase in overnight temps is due to sprawl and concrete/asphalt acting as heat batteries. Overnight temps are still reliably in the 80s, though. I was curious, so I went and checked the NWS historical data. It shows that monthly average lows for August are more or less unchanged in the past 30 years, FWIW.
