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 chance that a given day will be muggy in Santiago is essentially constant during February, remaining around 0% throughout.
For reference, on January 1, the muggiest day of the year, there are muggy conditions 0% of the time, while on January 9, the least muggy day of the year, there are muggy conditions 0% of the time.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.
The average hourly wind speed in Santiago is essentially constant during February, remaining within 0.2 miles per hour of 6.8 miles per hour throughout.
For reference, on January 4, the windiest day of the year, the daily average wind speed is 7.1 miles per hour, while on May 8, the calmest day of the year, the daily average wind speed is 5.5 miles per hour.
Average Wind Speed in February
The wind direction in Santiago during February is predominantly out of the west from February 1 to February 16 and the east from February 16 to February 29.

Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).
The growing season in Santiago typically lasts for 8.9 months (270 days), from around August 30 to around May 27, rarely starting before July 31 or after September 25, and rarely ending before May 4 or after June 24.
The month of February in Santiago is reliably fully within the growing season.
Time Spent in Various Temperature Bands and the Growing Season in February
Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.
The average accumulated growing degree days in Santiago are rapidly increasing during February, increasing by 551°F, from 2,407°F to 2,957°F, over the course of the month.

This report illustrates the typical weather in Santiago year round, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Santiago.
For each station, the records are corrected for the elevation difference between that station and Santiago 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 Santiago is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Santiago and a given station.
The stations contributing to this reconstruction are: Comodoro Arturo Merino Benítez International Airport (97%, 15 kilometers, northwest) and Curico (2.7%, 176 kilometers, south).
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , 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.
Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
