Spring Climate Summary

Moisture will push into the state from the east through the middle of the week, bringing chances for showers and thunderstorms primarily to the White Mountains, but as far west as Southern Gila County on Wednesday-Thursday. Rainfall potential will be limited, however, lightning strikes could lead to new fire starts in remote, higher terrain areas and strong, gusty outflow winds are expected with any thunderstorms that do develop.

HeatRisk will reach the Moderate category across the lower deserts beginning Wednesday as high temperatures approach 4-6 degrees above normal. Make sure to practice smart heat safety.

High temperatures across the lower deserts will increase to 100-108 degrees, or around 4-6 degrees above daily normals through the rest of the workweek. This will result in HeatRisk increasing to the Moderate category. Temperatures will decrease closer to normal by this weekend.

May of 2026 experienced on average above normal high and low temperatures, resulting in above normal mean temperatures for the month for the three climate sites (Phoenix, Yuma, and El Centro).

Spring of 2026 was the hottest meteorological Spring on record for the three climate sites (Phoenix, Yuma, and El Centro) and most of the region, largely driven by the historic March heat. It was also a very dry Spring.
