NYC declares Code Red as extreme heat grips the city this summer

New York City has issued guidance on staying safe during extreme heat as temperatures climb. A Code Red heat alert is declared when the heat index reaches 95°F for two straight days or hits 100°F on any single day. The city is urging residents to take precautions, especially those most vulnerable to heat-related illness.

The city activates a Code Red alert under two conditions. The first occurs when the heat index stays at 95°F or higher for at least two days in a row. The second happens if the heat index reaches 100°F or more on any given day.

During these alerts, the city increases shelter capacity and provides extra support for homeless populations. Officials advise all residents to stay updated on weather conditions, drink plenty of water, and seek out air-conditioned spaces or public cooling centres. Avoiding intense physical activity, particularly during the hottest parts of the day, is also recommended. Older adults, young children, and people with preexisting health conditions face the greatest risks. These groups are encouraged to take additional steps to protect themselves from heat exhaustion or heatstroke.

Residents can find more details and resources on the city’s official websites, NYC.gov/health and NYC.gov/beattheheat. The city’s measures aim to reduce health risks and provide relief during extreme heat events. Cooling centres and expanded shelters remain available to those in need.
