Arizona – Bright desert sun and dry air are already warming the ground quickly, and by mid-afternoon, Tucson will feel more like early summer than early April, with temperatures pushing close to 90°F.
According to the National Weather Service in Tucson, highs will reach the mid-80s today before climbing into the upper 80s Saturday and peaking near 91°F by Sunday. Overnight lows remain mild in the mid to upper 50s, limiting overnight cooling.
Across Tucson and along I-10 and I-19, drivers should expect clear roads but intense sun glare, especially during afternoon travel. The dry air and light winds will make the heat feel sharper under direct sunlight.
Outdoor plans will need adjusting through the weekend. Hydration becomes key by early afternoon, and shaded breaks are essential during peak heat. Pets and vehicles can heat up quickly, even in short periods.
The warming trend continues into early next week, with highs staying near 90°F before easing slightly midweek. Skies remain mostly clear, keeping conditions stable but increasingly warm.
By Monday and Tuesday, temperatures hold in the upper 80s to low 90s, signaling one of the first sustained warm stretches of the season. This early heat wave could catch some residents off guard.
