Event Summary

On 7/15/2026, New York City experienced continued extreme heat, with high temperatures and heat indices remaining elevated across the city. The event was compounded by smoke from wildfires in western Ontario, Canada, which moved into the region and contributed to degraded air quality. The City extended its Heat Emergency Plan operations through 7/16, including the availability of hundreds of cooling centers and enhanced outreach to protect New Yorkers from heat and poor air quality.
