Phoenix, Arizona – Unseasonably warm temperatures are creating minor heat concerns across the lower deserts this weekend.
According to the US National Weather Service in Phoenix, afternoon high temperatures will run well above normal Saturday and Sunday, with readings climbing into the low to mid 80s across much of south-central Arizona. These values are expected to be 8 to 14 degrees above seasonal averages, prompting a Minor HeatRisk designation.
Forecasters note that skies will remain mostly sunny, allowing temperatures to rise quickly during the afternoon hours. While the heat is not considered extreme, officials stress that prolonged outdoor exposure may still lead to heat-related stress, especially for individuals unaccustomed to warmer winter conditions.
Residents and visitors traveling along Interstate 10, I-17, U.S. 60, and Loop 101 may notice warmer-than-expected conditions during peak afternoon travel times. The National Weather Service advises staying hydrated, taking breaks in shaded or air-conditioned areas, and limiting strenuous outdoor activities during the warmest part of the day.
Sensitive groups—including older adults, young children, and outdoor workers—are encouraged to take additional precautions. Light-colored, loose-fitting clothing and sunscreen are also recommended when spending extended time outdoors.
The warm pattern is expected to persist through the weekend, with similar temperatures forecast on Sunday. Overnight lows will remain mild, offering limited cooling relief heading into early morning hours.
While no weather advisories or warnings are currently in effect, meteorologists emphasize that early-season heat can catch people off guard, particularly during winter months when heat safety is not top of mind.
These conditions may be especially noticeable for commuters, students, hikers, and weekend event attendees, as outdoor activities remain popular during the cooler months in the Valley.
Residents are encouraged to continue monitoring official National Weather Service updates for any changes to the forecast.
