Probability of Precipitation in November
To show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day.
The average sliding 31-day rainfall during November in Tromsø is decreasing, starting the month at 3.0 inches, when it rarely exceeds 5.2 inches or falls below 0.8 inches, and ending the month at 2.2 inches, when it rarely exceeds 4.1 inches or falls below 0.7 inches.
Average Monthly Rainfall in November
We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. As with rainfall, we consider the liquid-equivalent snowfall accumulated over a sliding 31-day period centered around each day.
The average sliding 31-day liquid-equivalent snowfall during November in Tromsø is gradually increasing, starting the month at 0.6 inches, when it rarely exceeds 1.8 inches, and ending the month at 1.1 inches, when it rarely exceeds 2.5 inches or falls below 0.1 inches.
Average Monthly Liquid-Equivalent Snowfall in November
Due to its extreme latitude, Tromsø experiences polar day (also known as the midnight Sun) during the summer and polar night during the winter. These are periods of time in which the sun is continuously above or below the horizon for more than one day. The precise start and end dates of polar day and night vary from year to year and depend on the precise location and elevation of the observer, and the local topography.
In the winter in Tromsø during 2017, the Sun is continuously below the horizon for 1.6 months, setting at 12:01 PM on November 26, and not rising again until 11:26 AM on January 15. As such, polar night begins in November on and lasts beyond the end of the month.
The longest day of the month is November 1, with 6 hours, 32 minutes of daylight.
Hours of Daylight and Twilight in November
The earliest sunrise of the month in Tromsø is 8:11 AM on November 1 and the latest sunrise is 2 hours, 49 minutes later at 11:00 AM on November 26.
The latest sunset is 2:42 PM on November 1 and the earliest sunset is 2 hours, 41 minutes earlier at 12:01 PM on November 26.
Daylight saving time is observed in Tromsø during 2017, but it neither starts nor ends during November, so the entire month is in standard time.

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 Tromsø is essentially constant during November, remaining around 0% throughout.
For reference, on July 6, the muggiest day of the year, there are muggy conditions 0% of the time, while on January 1, 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 Tromsø is gradually increasing during November, increasing from 4.5 miles per hour to 5.2 miles per hour over the course of the month.
For reference, on January 30, the windiest day of the year, the daily average wind speed is 6.0 miles per hour, while on August 1, the calmest day of the year, the daily average wind speed is 2.8 miles per hour.

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 in Tromsø is essentially constant during November, remaining within 0.1 kWh of 0.1 kWh throughout.

This report illustrates the typical weather in Tromsø 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 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Tromsø.
For each station, the records are corrected for the elevation difference between that station and Tromsø 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 Tromsø is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Tromsø and a given station.
The stations contributing to this reconstruction are: Tromsø Airport, Langnes (97%, 4.0 kilometers, north); Bardufoss Airport (1.4%, 68 kilometers, south); Sørkjosen Airport (1.1%, 79 kilometers, east); and Andøya Andenes Airport (0.6%, 117 kilometers, west).
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.
Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.
