Mesa, Arizona – Arizona kicks off June with rising summer heat, and Mesa residents should prepare for a steady climb toward triple-digit temperatures by Thursday. After a cooler-than-average Monday, June 3rd brings a sharp return to heat with a high of 96°F and clear skies dominating the region.
According to the National Weather Service in Phoenix, Tuesday will be sunny with calm winds becoming southwest around 5 mph by afternoon. No storms are in the forecast, but intense UV levels and heat stress risks will increase daily through Sunday, especially along US-60 and I-10.
Wednesday through Friday, temperatures will soar past 100°F—peaking at 104°F on Saturday. Low overnight humidity and calm winds may provide only slight relief. Residents should hydrate frequently, limit outdoor activity during peak hours, and check cooling systems now.
Power demands are expected to spike later this week. APS and SRP customers are encouraged to reduce energy use from 3–8 p.m. and report outages immediately.
While skies remain clear, early-season heatwaves like this one can strain infrastructure and public health systems, especially for older adults and outdoor workers.
Warnings remain in effect through the week, and updates are expected by Thursday if heat advisories become necessary.
