Heat advisory in effect across Western and Central New York
Sunday, July 6, a dangerous heat wave is gripping much of Upstate New York, prompting the National Weather Service in Buffalo to issue a heat advisory from 11:00 a.m. to 8:00 p.m.. The heat index—which combines temperature and humidity—is expected to soar into the upper 90s to around 100°F (37°C to 38°C), increasing the risk of heat-related illnesses.
Areas most affected by this intense heat include Western New York counties such as Niagara, Orleans, Monroe, Wayne, Northern Cayuga, Oswego, Genesee, Livingston, and Ontario, as well as Central New York counties including Onondaga, Seneca, and Southern Cayuga.
Although temperatures alone may hover in the low to mid 90s°F (33°C to 35°C), the high humidity levels will make it feel significantly hotter, particularly during the early afternoon through early evening hours.
Outdoor workers, especially those exposed to direct sun, are facing hazardous conditions and are strongly encouraged to take frequent breaks in shaded or cool areas. According to OSHA guidance, extended exposure under these conditions can trigger heat exhaustion or even heat stroke.
The early July sun remains intense across New York State, and combined with the stagnant air, it contributes to poor air quality and increased discomfort, particularly in urban areas like Rochester, Syracuse, and Buffalo, where heat tends to accumulate on asphalt and concrete surfaces.
July 6 is shaping up to be one of the hottest days of the month so far in the Empire State, and humidity levels are expected to remain elevated overnight, offering little relief into Monday morning.
