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.

Fandriana experiences some seasonal variation in the perceived humidity.

The muggier period of the year lasts for 3.8 months, from December 8 to April 3, during which time the comfort level is muggy, oppressive, or miserable at least 4% of the time. The muggiest day of the year is February 8, with muggy conditions 17% of the time.

The least muggy day of the year is July 31, when muggy conditions are essentially unheard of.

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 Fandriana is from the east throughout the year.

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 3.2 months, from September 13 to December 20, with an average daily incident shortwave energy per square meter above 6.3 kWh. The brightest day of the year is November 8, with an average of 6.9 kWh.

The darker period of the year lasts for 2.5 months, from May 17 to August 2, with an average daily incident shortwave energy per square meter below 4.7 kWh. The darkest day of the year is July 3, with an average of 4.2 kWh.

Fandriana 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 Fandriana, 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.
