Phoenix is expected to reach its first 90-degree high of the year next week, a milestone that normally doesn't arrive until the end of March. The long-term average first 90-degree day in Phoenix occurs around March 30, but the city could be about a month ahead of schedule, with the earliest 90-degree day on record set back in 2016 on February 16.

Why it matters

The early arrival of 90-degree temperatures in Phoenix is an indicator of the region's ongoing battle with the effects of climate change, which is causing hotter and drier conditions to arrive sooner each year. This puts a strain on the city's infrastructure, public health, and natural resources, and highlights the need for proactive measures to adapt to a changing climate.
