Yuma, Arizona – Residents woke up to unusually warm overnight conditions early Sunday, with temperatures refusing to drop below 69°F by sunrise, keeping homes, roads, and infrastructure warmer than typical for late March.
According to the National Weather Service in Phoenix, Yuma recorded a low of 69°F while El Centro set a new record warm low of 68°F, breaking the previous record of 63°F set in 2004. These readings sit more than 10 degrees above seasonal norms, where lows typically fall near the mid-50s.
Across southwest Arizona and into California’s Imperial Valley, the elevated overnight temperatures reduce cooling efficiency for homes and increase early-morning energy demand. In Yuma, air conditioning systems may run longer into the overnight hours, while urban heat retention keeps pavement and buildings warmer through the morning commute.
Drivers won’t face weather-related hazards like ice or fog, but the lack of overnight cooling can contribute to heat fatigue, especially for outdoor workers starting shifts before sunrise. Hydration and adjusting work schedules remain key precautions.
Warm overnight lows are expected to persist into early next week, with additional records possible if temperatures fail to drop below the upper 60s again. Further updates may be issued as conditions evolve.
