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 Siem Reap is very rapidly increasing during February, rising from 34% to 59% over the course of the month.
For reference, on June 1, the muggiest day of the year, there are muggy conditions 100% of the time, while on January 15, the leasy muggy day of the year, there are muggy conditions 29% 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 Siem Reap is essentially constant during February, remaining within 0.1 miles per hour of 2.8 miles per hour throughout.
For reference, on August 6, the windiest day of the year, the daily average wind speed is 3.7 miles per hour, while on October 6, the calmest day of the year, the daily average wind speed is 2.4 miles per hour.

Siem Reap is further than 200 kilometers from the nearest reliable weather station, so the weather-related data on this page were taken entirely from NASA's MERRA-2 satellite-era reanalysis . 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.
The temperature and dew point estimates are corrected for the difference between the reference elevation of the MERRA-2 grid cell and the elevation of Siem Reap, according to the International Standard Atmosphere .
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.
