NYC Heat Emergency Plan for July 4 weekend: cooling centers & COOL vans
New York, NY’s Heat Emergency Plan for the July 4 weekend adds cooling centers, COOL vans, LinkNYC directions, and worker protections—here’s how to use it.
On June 29, 2026, Mayor Zohran Kwame Mamdani activated an unprecedented NYC Heat Emergency Plan as dangerously high heat indices were forecast for the July 4 weekend. The point wasn’t just to open extra places to cool down—it was to build a citywide response that helps residents, workers, and vulnerable New Yorkers find relief fast.
What the Heat Emergency Plan does in practice
When extreme heat is approaching, the city surges cooling access and outreach across all five boroughs. In the July 4 activation, that included hundreds of cooling centers, expanded mobile and outdoor-worker cooling resources, and targeted reminders to employers about heat-related worker protections.
City guidance also emphasized real-time support: sign up for Notify NYC for alerts, and use NYC’s tools (including LinkNYC kiosks) to get to a cooling center quickly.
Where to go for relief: Cooling Centers 101
The city planned to open hundreds of cooling centers across all five boroughs starting Wednesday, with options at public locations such as hospitals and libraries. The city stressed that residents should use the Cool Options Map (linked through NYC’s heat guidance page) or call 311 to find the nearest cooling center, including accessible and pet-friendly locations.
During the holiday weekend, some large indoor spaces were converted specifically for cooling. The Javits Center and NYC Emergency Management headquarters were scheduled to serve as cooling centers from 11 a.m. to 11 p.m. on July 3 through July 5.
Get directions fast with LinkNYC
If you’re unsure where your nearest cooling center is, LinkNYC kiosks displayed real-time walking directions to the closest cooling option within a 10-minute walk.
Mobile help: COOL vans and in-home wellness checks
NYC Health + Hospitals launched Cooling Outreach On-Location (COOL) vans as part of the July 4 heat response. The city described the vans as medical-style outreach that can provide wellness checks and medical care, plus practical cooling resources such as water and electrolytes. The vans can also deliver meals/snacks and help with transport to cooling centers or healthcare facilities.
For older adults, the plan also included COOL in-home wellness checks. These in-home teams were described as staffed with trained medical staff, including paramedics and nurse practitioners, focused on identifying needs for heat relief.
Support for outdoor workers: pop-up cooling stations
The city expanded pop-up cooling stations for outdoor workers, including street vendors, deliveristas, and day laborers. During the activation, those outdoor relief points were described as offering cold water, misting fans, and cooling towels on days when heat advisories are issued.
Work-safety and rights during extreme heat
Heat affects workplaces as well as neighborhoods. For the July 4 activation, NYC’s Department of Consumer and Worker Protection planned to message licensees, reminding employers of NYCEM’s extreme heat guidance, encouraging heat safety plans, and urging compliance with NYC labor law—including guidance that most NYC workers can use Protected Time Off to treat or heal from heat-related illness.
In its press-conference guidance, the city urged employers to plan ahead, build flexibility into schedules, and make sure workers aren’t penalized for staying safe—whether that means taking time for health, getting to cooling resources, or adjusting work during the hottest hours.
What you should do now, before the next activation
Even though this particular activation happened for the late-June/July 4 heat window, the steps remain the same for future extreme-heat days:
- Make a heat plan for yourself and your household (and check on neighbors, especially seniors).
- Use NYC’s cooling tools: Cool Options Map and 311 to locate the nearest cooling center.
- Know how you’ll get directions quickly (LinkNYC kiosks during heat events).
- Enroll in Notify NYC so you can get rapid updates; the city told residents to text NOTIFYNYC to 692-692.
- Call 911 immediately if someone shows warning signs such as confusion, trouble breathing, rapid heartbeat, dizziness, nausea or vomiting, or hot dry skin.
Cooling-center availability and hours can change with each heat event, so the city’s map and Notify NYC alerts are the best way to confirm what’s available during the next surge.
