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.
The perceived humidity level in Lost Hills, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.

Temperature and Dew Point
There are 6 weather stations near enough to contribute to our estimation of the temperature and dew point in Lost Hills.
For each station, the records are corrected for the elevation difference between that station and Lost Hills according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Lost Hills is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Lost Hills and a given station.
The stations contributing to this reconstruction are: Meadows Field (24%, 61 kilometers, east); Porterville Municipal Airport (18%, 73 kilometers, northeast); Hanford Municipal Airport (16%, 78 kilometers, north); Lemoore Naval Air Station (Reeves Field) (15%, 83 kilometers, north); Paso Robles Municipal Airport (14%, 85 kilometers, west); and San Luis Obispo County Airport (12%, 96 kilometers, southwest).
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.
Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.
