The patented, exclusive AccuWeather RealFeel Temperature is an index that describes what the temperature really feels like. It's a unique composite of everything that affects how warm or cold a person feels, and measures the effects of temperature, wind, humidity, sunshine intensity, cloudiness, precipitation and elevation on the human body.

Temperature by itself gives only part of the picture. Other weather measurements, like Wind Chill or Heat Index, include only the temperature and one additional element like wind speed or humidity. Many measures are designed to rate effects on an inanimate object or an unclothed person, so they don't tell what it really feels like to someone who is appropriately dressed. Only the AccuWeather RealFeel Temperature includes every measurement relative to how the temperature feels to a person.

For example, on a steamy July day without a breath of wind and with the noon sun beating down, the official temperature (which is measured in the shade) may be 92 degrees. But when you stand outside in the humidity and scorching sun, it may feel like 118 degrees. In contrast, when the official temperature is 92 degrees with a nice breeze, low humidity and bright sunshine, but late in the day so the sun intensity is not as strong, it may feel like 86 degrees.

Departure is a handy way to check the weather for a trip - you can see the forecast for when you are leaving, (plus and minus 1 hour) and the weather for when you are arriving (again, plus and minus one hour.)

Simply type in a city, state or zipcode in each box for where you are leaving from and going to, and select the appropriate date and time. Currently this feature does not support airport names and codes, although we're looking to add that soon.
