Wind chill index values for a range of temperatures and wind speeds, from the standard wind chill formula for Environment Canada. Wind chill (popularly wind chill factor) is the sensation of cold produced by the wind for a given ambient air temperature on exposed skin as the air motion accelerates the rate of heat transfer from the body to the surrounding atmosphere.
The answer to "feels like" temperature, according to the National Weather Service, has to do with wind, or wind chill to be more specific. While the actual temperature signifies the temperature of ...
If the temperature is 0 degrees and the wind is blowing at 15 mph, the wind chill is 19 degrees below zero. Low wind chill numbers are a sign you need to dress for colder conditions.
This chart lets you estimate the wind chill without having to do the math yourself. Find the value closest to the temperature at the top of the chart and the wind speed to the left.
The heat index and humidex measure the effect of humidity on the perception of temperatures above +27 °C (81 °F). In humid conditions, the air feels much hotter, because less perspiration evaporates from the skin. The wind chill factor measures the effect of wind speed on cooling of the human body below 10 °C (50 °F). As airflow increases ...
A sustained wet-bulb temperature of about 35 °C (95 °F) can be fatal to healthy people; at this temperature our bodies switch from shedding heat to the environment, to gaining heat from it. [10] Thus a wet bulb temperature of 35 °C (95 °F) is the threshold beyond which the body is no longer able to adequately cool itself. [11]
With high wind speeds forecasted in the state, it'll feel much colder than the actual temperature. Here's what to know about wind chill and what the term means.
This product replaced the Wind Chill Watch in October 2024. [42] [43] Cold weather advisory NPW – Seasonably cold air temperatures or wind chill values, but not extremely cold values, are expected or occurring. The temperature and wind chill criteria vary significantly over different county warning areas based on climate variability.
