Tucson, AZ – Arizona residents should brace for an early spring heat surge as Tucson temperatures climb into the 90s through the weekend, raising fire risk across the region, especially along I-10. Wednesday’s high is forecast at 92°F, following a scorching 96°F on Tuesday — well above seasonal averages for late March.
According to the National Weather Service, sunny and dry conditions will dominate southern Arizona through Sunday, with daily highs ranging from 87°F to 96°F. Overnight lows will hover in the upper 50s to low 60s, offering only limited relief. Light winds are expected to shift directions throughout the week, but gusts may increase by Thursday afternoon, adding concern for dry brush ignition near major roadways like Interstate 10.
Fire safety officials recommend avoiding open flames, properly disposing of cigarettes, and staying alert to Red Flag Warnings. Those traveling along I-10 should be cautious of potential visibility issues if dust and wind pick up later this week.
Wednesday will be partly sunny with increasing clouds Tuesday night and mild winds throughout the region. The extended forecast holds mostly clear nights and highs staying in the low 90s through Friday. By Saturday and Sunday, temperatures will ease slightly into the low 80s, though dry conditions will persist.
As spring sets in across Arizona, residents are urged to monitor local weather alerts and stay hydrated. With no rain in sight, early-season heat and fire risk remain the primary concern for southern Arizona through early next week.
