RainfallTo show variation within the season and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day rainfall during the fall at Norilsk-Alykel Airport is very rapidly decreasing, starting the season at 2.2 inches, when it rarely exceeds 3.6 inches or falls below 0.9 inches, and ending the season at 0.0 inches, when it rarely exceeds 0.0 inches or falls below -0.0 inches. SnowfallAs with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day snowfall during the fall at Norilsk-Alykel Airport is very rapidly increasing, starting the season at 0.2 inches, when it rarely exceeds 0.6 inches or falls below -0.0 inches, and ending the season at 8.7 inches, when it rarely exceeds 17.4 inches or falls below 0.9 inches. The highest average 31-day accumulation is 10.6 inches on November 1. SunDue to its extreme latitude, Norilsk-Alykel Airport 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 at Norilsk-Alykel Airport during 2024, the Sun is continuously below the horizon for 1.5 months, setting at 1:23 PM on November 28, and not rising again until 12:53 PM on January 14. As such, polar night begins in the fall and lasts beyond the end of the season. The longest day of the fall is September 1, with 15 hours, 17 minutes of daylight. The earliest sunrise of the fall at Norilsk-Alykel Airport is 5:30 AM on September 1 and the latest sunrise is 7 hours, 2 minutes later at 12:32 PM on November 28. The latest sunset is 8:47 PM on September 1 and the earliest sunset is 7 hours, 24 minutes earlier at 1:23 PM on November 28. Daylight saving time is not observed at Norilsk-Alykel Airport during 2024. The figure below presents a compact representation of the sun's elevation (the angle of the sun above the horizon) and azimuth (its compass bearing) for every hour of every day in the reporting period. The horizontal axis is the day of the year and the vertical axis is the hour of the day. For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. The black isolines are contours of constant solar elevation. MoonThe figure below presents a compact representation of key lunar data for the fall of 2024. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon. HumidityWe 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 at Norilsk-Alykel Airport is essentially constant during the fall, remaining around 0% throughout. For reference, on July 26, 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. WindThis 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 at Norilsk-Alykel Airport is very rapidly increasing during the fall, increasing from 9.5 miles per hour to 13.7 miles per hour over the course of the season. For reference, on December 13, the windiest day of the year, the daily average wind speed is 14.4 miles per hour, while on August 14, the calmest day of the year, the daily average wind speed is 9.3 miles per hour. The hourly average wind direction at Norilsk-Alykel Airport throughout the fall is predominantly from the south, with a peak proportion of 68% on November 30. Growing SeasonDefinitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere). The growing season at Norilsk-Alykel Airport typically lasts for 3.0 months (92 days), from around June 8 to around September 8, rarely starting before May 23 or after June 24, and rarely ending before August 22 or after September 25. During the fall at Norilsk-Alykel Airport, the chance that a given day is within the growing season is very rapidly decreasing falling from 69% to 0% over the course of the season. Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F. The average accumulated growing degree days at Norilsk-Alykel Airport are essentially constant during the fall, remaining within 10°F of 519°F throughout. Solar EnergyThis 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 at Norilsk-Alykel Airport is very rapidly decreasing during the fall, falling by 2.3 kWh, from 2.3 kWh to 0.0 kWh, over the course of the season.

Data SourcesThis report illustrates the typical weather at Norilsk-Alykel Airport, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Temperature and Dew PointNorilsk-Alykel Airport has a weather station that reported reliably enough during the analysis period that we have included it in our network. When available, historical temperature and dew point measurements are taken directly from this weather station. These records are obtained from NOAA's Integrated Surface Hourly data set, falling back on ICAO METAR records as required. There are no other weather stations in our network within 200 kilometers of this location. Consequently, in the case of missing or erroneous measurements from this station, we fall back on NASA's MERRA-2 modern-era reanalysis , adjusted according to typical seasonal and diurnal differences between this station and the wide-area MERRA-2 reconstructed values.Other DataAll data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , 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. Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.

Weather data is prone to errors, outages, and other defects. We assume no responsibility for any decisions made on the basis of the content presented on this site. We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands. We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
