Medford, Oregon – Triple-digit heat is set to scorch southern Oregon this weekend, with Medford, Ashland, and Grants Pass facing the highest risk as an intense ridge builds over the region. Residents across Jackson and Josephine counties should prepare for dangerous temperatures through late Sunday.
According to the National Weather Service in Medford, an Excessive Heat Warning remains in effect for much of southwest Oregon until Sunday night, with temperatures expected to climb above 100°F in valley locations. The heat risk map highlights significant threats not only for major cities but also along the I-5 corridor, Highway 199, and outlying communities.
Heat-sensitive groups—including the elderly, young children, and those with chronic illnesses—should take extra precautions. Health officials advise shifting outdoor activities to early morning or evening, wearing light-colored clothing, drinking water frequently, and seeking air-conditioned spaces. Some cooling centers have opened in Medford and Grants Pass to help residents cope.
Weekend events, travel plans, and outdoor recreation may be disrupted, and power grids could be strained by increased air conditioning use. This level of heat is rare for July and is similar to the 2021 Pacific Northwest heatwave that caused widespread impacts.
Dangerous heat conditions will persist until at least Sunday night. More advisories may follow if the pattern continues into next week.
