Buffalo, NY – Western New York is in for a stretch of summer heat as a stubborn high-pressure system off the New England coast locks in sunny, dry conditions through the weekend. According to the National Weather Service in Buffalo, temperatures will steadily climb, with heat and humidity peaking Sunday as heat index values reach into the mid-90s across the Lake Plain and Finger Lakes regions.
Today and Saturday will stay mostly sunny, with highs in Buffalo, Rochester, and Niagara Falls ranging from the upper 70s to upper 80s. Overnight lows will offer little relief, dipping only into the mid-60s for many areas. By Sunday, the heat index could soar past 95° for locations near Batavia, Geneva, and along the Lake Ontario shoreline, increasing risks for heat exhaustion—especially for those without reliable air conditioning.
Residents are urged to stay hydrated, limit outdoor activity during the afternoon, and check on vulnerable neighbors and pets as the heat builds. Drivers should never leave children or animals in parked vehicles, even for a few minutes. Cooling centers may open if heat advisories are issued, and updates will be posted by local emergency management offices.
The stretch of hot weather is expected to linger into early next week, so those in Western and Central New York should keep an eye on forecast updates and prepare for more above-average heat.
