The New York State Department of Health reminded residents to protect against extreme heat as the warm season began, tying its advisory to an Air Quality Health Advisory for ozone covering the New York City Metro and Lower Hudson Valley regions, per a DOH press release, May 18, 2026. The guidance lands squarely on Rockland County, which sits inside the advisory region and regularly records some of the warmer summer temperatures in the Hudson Valley.
State heat advisories generally trigger when the heat index reaches 95 degrees or higher for two or more consecutive days, or on any single day reaching 100 degrees, thresholds consistent with regional health department definitions. The state also operates a heat surveillance dashboard that tracks outdoor conditions and heat-related illness from May 1 through September 30, per the Department of Health.
For Rockland, the risk profile is specific. Older residents in river villages without air conditioning, outdoor workers on road and construction crews, and apartment dwellers in Spring Valley and Nyack's denser blocks are the populations the state's guidance targets. County residents can act on three of its core recommendations now: drink water before feeling thirsty, move outdoor errands and exercise to morning hours, and check on neighbors over 65 during any stretch above 90 degrees.
The state has also moved on the utility side. The Public Service Commission adopted a policy in 2026 protecting residential customers from utility shut-offs during extreme heat, meaning households behind on electric bills should not face disconnection during a heat event, per state materials.

Heat is statistically the deadliest weather in the United States, and its burden falls unevenly. The state's dashboard exists precisely to make that unevenness visible, and Rockland's villages, senior centers and school athletic departments would do well to check it before scheduling August events, practices and outdoor work shifts.
County resources fill in around the state guidance. Rockland's villages and the county provide cooling spaces during declared heat events, and local senior centers and libraries routinely serve as the first stop for residents without reliable air conditioning. During any multi-day stretch above 90 degrees, the state's own checklist reduces to four moves: hydrate, limit outdoor exertion to early morning, use air conditioning or seek a cooling space during peak afternoon hours, and check on older neighbors and anyone living alone, the groups that account for most preventable heat deaths in the region.
