To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day in the year. Lucknow experiences very significant seasonal variation in monthly rainfall.
The rainy period of the year lasts for 9.7 months, from January 11 to November 1, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around July 21, with an average total accumulation of 9.0 inches.
The rainless period of the year lasts for 2.3 months, from November 1 to January 11. The least rain falls around November 22, with and average total accumulation of 0.2 inches.
Average Monthly Rainfall
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.
Lucknow experiences very significant seasonal variation in the perceived humidity.
The muggier period of the year lasts for 5.6 months, from May 11 to October 30, during which time the comfort level is muggy, oppressive, or miserable at least 26% of the time. The muggiest day of the year is August 17, with muggy conditions 100% of the time.
The least muggy day of the year is January 11, when muggy conditions are essentially unheard of.

Temperature and Dew Point
There is only a single weather station, Chaudhary Charan Singh Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Lucknow.
At a distance of 9 kilometers from Lucknow, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.
The station records are corrected for the elevation difference between the station and Lucknow according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.
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.
