Fall Weather in Āsosa EthiopiaDaily high temperatures increase by 9°F, from 73°F to 82°F, rarely falling below 70°F or exceeding 89°F. Daily low temperatures are around 59°F, rarely falling below 55°F or exceeding 63°F. The highest daily average low temperature is 60°F on September 30. For reference, on March 18, the hottest day of the year, temperatures in Āsosa typically range from 65°F to 92°F, while on December 28, the coldest day of the year, they range from 57°F to 84°F. The figure below shows you a compact characterization of the hourly average fall temperatures. The horizontal axis is the day, the vertical axis is the hour of the day, and the color is the average temperature for that hour and day. Mali, Guinea (3,178 miles away) is the far-away foreign place with temperatures most similar to Āsosa (view comparison). CloudsThe fall in Āsosa experiences very rapidly decreasing cloud cover, with the percentage of time that the sky is overcast or mostly cloudy decreasing from 73% to 44%. The clearest day of the fall is November 30, with clear, mostly clear, or partly cloudy conditions 56% of the time. For reference, on July 24, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 83%, while on December 16, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 58%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Āsosa, the chance of a wet day over the course of the fall is very rapidly decreasing, starting the season at 77% and ending it at 3%. For reference, the year's highest daily chance of a wet day is 79% on August 24, and its lowest chance is 1% on January 15. 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 in Āsosa is very rapidly decreasing, starting the season at 7.7 inches, when it rarely exceeds 14.5 inches or falls below 2.8 inches, and ending the season at 0.2 inches, when it rarely exceeds 0.4 inches or falls below -0.0 inches. SunOver the course of the fall in Āsosa, the length of the day is decreasing. From the start to the end of the season, the length of the day decreases by 43 minutes, implying an average daily decrease of 29 seconds, and weekly decrease of 3 minutes, 21 seconds. The shortest day of the fall is November 30, with 11 hours, 35 minutes of daylight and the longest day is September 1, with 12 hours, 18 minutes of daylight. The earliest sunrise of the fall in Āsosa is 6:30 AM on October 9 and the latest sunrise is 13 minutes later at 6:43 AM on November 30. The latest sunset is 6:50 PM on September 1 and the earliest sunset is 34 minutes earlier at 6:16 PM on November 15. Daylight saving time is not observed in Āsosa during 2024. For reference, on June 20, the longest day of the year, the Sun rises at 6:22 AM and sets 12 hours, 43 minutes later, at 7:04 PM, while on December 21, the shortest day of the year, it rises at 6:53 AM and sets 11 hours, 32 minutes later, at 6:26 PM. 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 in Āsosa is very rapidly decreasing during the fall, falling from 33% to 1% over the course of the season. The highest chance of a muggy day during the fall is 35% on September 27. For reference, on September 27, the muggiest day of the year, there are muggy conditions 35% of the time, while on February 13, 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 in Āsosa is gradually increasing during the fall, increasing from 4.8 miles per hour to 5.4 miles per hour over the course of the season. For reference, on February 15, the windiest day of the year, the daily average wind speed is 7.3 miles per hour, while on October 9, the calmest day of the year, the daily average wind speed is 4.0 miles per hour. The lowest daily average wind speed during the fall is 4.0 miles per hour on October 9. The wind direction in Āsosa during the fall is predominantly out of the south from September 1 to October 10 and the east from October 10 to 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). Temperatures in Āsosa are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year. 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 in Āsosa are very rapidly increasing during the fall, increasing by 1,598°F, from 5,083°F to 6,682°F, over the course of the season. 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 in Āsosa is gradually increasing during the fall, rising by 0.9 kWh, from 5.0 kWh to 5.9 kWh, over the course of the season. The highest average daily incident shortwave solar energy during the fall is 5.9 kWh on November 16. TopographyFor the purposes of this report, the geographical coordinates of Āsosa are 10.067 deg latitude, 34.533 deg longitude, and 5,020 ft elevation.

Within 10 miles contains very significant variations in elevation (3,215 feet). Within 50 miles contains large variations in elevation (5,778 feet). The area within 2 miles of Āsosa is covered by cropland (65%), grassland (14%), and trees (12%), within 10 miles by grassland (33%) and cropland (31%), and within 50 miles by grassland (36%) and trees (36%). Data SourcesThis report illustrates the typical weather in Āsosa, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Āsosa 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 Āsosa, 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 Algorithms 2nd Edition , by Jean Meeus. 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.
