February Climate Summary

Warmest Winter on Record

Temperatures will remain near record levels to start the week, but will gradually cooldown through the week as the weather pattern shifts away from high pressure ridging to low pressure troughing. This shift will also bring some breezier conditions, especially on Thursday.

High pressure over the region will continue to lead to well above normal temperatures. Afternoon highs will reach the middle 80s to high 80s across the lower deserts and in the mid 70s to high 70s across the higher terrain. This heat will result in Minor HeatRisk. So make sure to use extra precautions if spending time outdoors, especially if you're more sensitive to the heat.

The Climate Prediction Center's (CPC) 6-10 day outlook has put the region under leaning above normal temperatures and leaning above normal precipitation, for March 8th - March 12th, 2026.

This was the warmest February on record for Phoenix and El Centro and Yuma recorded the 5th warmest February on record. Mean temperatures at all 3 climate sites were between 6 to 8 degrees above the monthly average.

It was officially the warmest meteorological winter (Dec-Feb) on record in Phoenix with an average temperature of 64.0 degrees. This shatters the previous record of 61.3 degrees set last winter.
