Wet-bulb globe temperature (WBGT) is the heat measure that actually tracks danger to the body. Unlike the plain air temperature on your phone, it folds in humidity, wind, and direct sun: the factors that decide whether your sweat can still cool you. It’s the standard the military, athletic associations, and occupational-safety bodies use to call when outdoor activity is no longer safe.
That matters in Stamford because coastal Fairfield County humidity off the Sound makes summer heat waves feel heavier and slower to break overnight. The number above is the live outdoor WBGT for the city right now; tap through to the live map to inspect any neighborhood, scrub the forecast hour by hour, and see the 7-day outlook.

Air temperature ignores humidity, wind, and sun: the things that decide whether heat is dangerous. Stamford's climate (coastal Fairfield County humidity off the Sound makes summer heat waves feel heavier and slower to break overnight.) is exactly why a single "feels-like" or thermometer reading can understate the real risk. WBGT captures all of it in one number.
