Buffalo, NY – Hot, sunny weather is on tap for Buffalo and western New York, with the region headed into a multi-day stretch of summer heat that could push heat index values into the low to mid-90s from Sunday through Tuesday. Temperatures will steadily climb through the weekend, and afternoons will feel especially hot in neighborhoods away from Lake Erie and Lake Ontario.
According to the National Weather Service in Buffalo, this heat build-up is expected to impact lower elevations, with peak temperatures Sunday, Monday, and Tuesday bringing increased risk for heat-related illness—especially for the elderly, young children, and those without reliable air conditioning. Southwest winds around 7 mph will offer only limited relief. No hazardous storms are expected, but residents should avoid strenuous outdoor activity during peak afternoon hours, stay hydrated, and check in on neighbors who may need assistance.
Sunny skies and warm nights will make this a popular window for lake outings, festivals, and outdoor dining, but the extended heat will increase stress on local utilities and may prompt cooling center openings if conditions worsen. Look for cooler, more comfortable air to return by midweek, with a chance for showers and storms by Tuesday night into Wednesday.
Stay alert for any additional advisories as the heat lingers, and use this sunny stretch for summer fun—just take steps to beat the heat and watch for updates.
