Sunrise & Sunset with Twilight and Daylight Saving Time
We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.
Windsor Airport experiences significant seasonal variation in the perceived humidity.
The muggier period of the year lasts for 3.6 months, from June 4 to September 21, during which time the comfort level is muggy, oppressive, or miserable at least 9% of the time. The muggiest day of the year is August 1, with muggy conditions 37% of the time.
The least muggy day of the year is December 9, when muggy conditions are essentially unheard of.

Temperature and Dew Point
Windsor Airport has a weather station that reported reliably enough during the analysis period that we have included it in our network. When available, historical temperature and dew point measurements are taken directly from this weather station. These records are obtained from NOAA's Integrated Surface Hourly data set, falling back on ICAO METAR records as required.
In the case of missing or erroneous measurements from this station, we fall back on records from nearby stations, adjusted according to typical seasonal and diurnal intra-station differences. For a given day of the year and hour of the day, the fallback station is selected to minimize the prediction error over the years for which there are measurements for both stations.
The stations on which we may fall back include but are not limited to Detroit City Airport, Harrow Auto, Grosse Ile Municipal Airport, Oakland-Troy Airport, Selfridge Air National Guard Base, Detroit Metropolitan Wayne County Airport, Point Pelee, and Willow Run Airport.
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.
