First 90° Day Stats

Temperatures warm through the week with the first 90s of the year later this week and potential for daily records. There is even good potential (75% chance) of tying or breaking the February record high in Phoenix.

Strong high pressure over the region this week will lead to well above normal temperatures. Afternoon highs will go from the lower 80s to start the week to the low 90s by the end of the week. Highs in the 80s and low 90s will result in Minor HeatRisk across the lower deserts. So make sure to use extra precautions if spending time outdoors, especially if you're more sensitive to the heat.

A broad area of high pressure ridging will support well above normal temperatures and dry conditions across the Desert Southwest through the beginning of March.

The average first 90° for all three of our climate sites occurs in mid to late March. However, the earliest 90° for all of the climate sites has already passed. So even though we're forecasting for all three sites to reach 90°+ by the end of the week it won't be the earliest occurrence.
