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 Bahir Dar, 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.

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 predominant average hourly wind direction in Bahir Dar varies throughout the year.

The wind is most often from the east for 2.1 months, from September 26 to November 28, with a peak percentage of 60% on October 21. The wind is most often from the north for 9.9 months, from November 28 to September 26, with a peak percentage of 38% on January 1.

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.

The average daily incident shortwave solar energy experiences some seasonal variation over the course of the year.

The brighter period of the year lasts for 3.5 months, from February 1 to May 17, with an average daily incident shortwave energy per square meter above 6.5 kWh. The brightest day of the year is April 8, with an average of 7.1 kWh.

The darker period of the year lasts for 1.7 months, from July 1 to August 23, with an average daily incident shortwave energy per square meter below 4.9 kWh. The darkest day of the year is July 25, with an average of 4.3 kWh.

Bahir Dar 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 Bahir Dar, according to the International Standard Atmosphere .
