Medford, Oregon- The National Weather Service has issued a Heat Advisory for Jackson County and surrounding areas, including Medford, effective 11 a.m. Sunday, June 8 through 8 p.m. Monday, June 9, amid forecasted temperatures pushing into the high 90s and possibly topping 100 °F.
Temperatures are expected to climb into the mid- to upper‑90s—potentially reaching or exceeding 100 °F—especially west of the Cascades over the Rogue Valley. HeatRisk levels have been elevated to “moderate,” signaling a heightened threat of heat-related illnesses for vulnerable populations.
Heat health officials in Oregon advise the following precautions:
Drink plenty of water and hydrate before feeling thirsty. Wear loose, light-colored clothing and apply shade when outdoors. Avoid strenuous outdoor activity between midday and early evening. Take frequent breaks in shaded or air-conditioned areas.
According to the NWS office in Medford, the advisory targets “individuals sensitive to heat, especially those without effective cooling and/or adequate hydration, and anyone doing strenuous outdoor activities.” They caution that local hospitals and heat-sensitive occupations could see elevated demand.
The warming trend is fueled by an upper-level ridge parked off the West Coast. A weak trough is expected to bring the slight chance of afternoon thunderstorms Sunday and Monday, but those won’t significantly disrupt the heat regime.
NWS reminds residents that sweltering temperatures will not significantly drop overnight, reducing the body’s ability to recover daily from the heat . Sunday and Monday nights will remain warm, with lows staying high and humidity persisting.
The advisory also coincides with recreational hazards: Pacific Coast stream and lake water remains cold and fast, and officials strongly encourage wearing life jackets when swimming or recreating near water.
Local public health agencies, including the Oregon Health Authority, urge residents—particularly young children, older adults, and those with chronic medical conditions—to closely monitor heat exposure and recognize warning signs of heat-related illnesses, such as muscle cramps, dizziness, heavy sweating, or fainting . If symptoms escalate—especially to fever above 103 °F with hot, dry skin—call 911 immediately.
Areas with limited or no air conditioning are encouraged to use public cooling spaces, such as the city’s splash pads, public libraries, or designated cooling centers. Residents can call 2-1-1 for assistance and information.
By Tuesday, meteorologists say temperatures will finally drop back to near-seasonal levels as the ridge shifts east and Pacific influences return.
