PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Bushenyi varies very significantly throughout the year. The wetter season lasts 8.5 months, from September 6 to May 23, with a greater than 39% chance of a given day being a wet day. The chance of a wet day peaks at 66% on April 27. The drier season lasts 3.4 months, from May 23 to September 6. The smallest chance of a wet day is 10% on July 4. Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 66% on April 27. Daily Chance of Precipitation
The percentage of days in which various types of precipitation are observed, excluding trace quantities: rain alone, snow alone, and mixed (both rain and snow fell in the same day).

Sunrise & Sunset with Twilight
The solar day over the course of the year 2017. From bottom to top, the black lines are the previous solar midnight, sunrise, solar noon, sunset, and the next solar midnight. The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray.
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. Bushenyi experiences some seasonal variation in the perceived humidity. The muggier period of the year lasts for 8.6 months, from September 17 to June 5, during which time the comfort level is muggy, oppressive, or miserable at least 4% of the time. The muggiest day of the year is April 26, with muggy conditions 14% of the time. The least muggy day of the year is July 18, when muggy conditions are essentially unheard of. Humidity Comfort Levels
The percentage of time spent at various humidity comfort levels, categorized by dew point: dry < 55°F < comfortable < 60°F < humid < 65°F < muggy < 70°F < oppressive < 75°F < miserable.
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 Bushenyi does not vary significantly over the course of the year, remaining within 0.4 miles per hour of 2.7 miles per hour throughout.Average Wind Speed
The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.
The predominant average hourly wind direction in Bushenyi varies throughout the year. The wind is most often from the north for 2.0 weeks, from January 14 to January 28, with a peak percentage of 37% on January 16. The wind is most often from the east for 12 months, from January 28 to January 14, with a peak percentage of 42% on January 1. Wind Direction
The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions (north, east, south, and west), excluding hours in which the mean wind speed is less than 1 mph. The lightly tinted areas at the boundaries are the percentage of hours spent in the implied intermediate directions (northeast, southeast, southwest, and northwest).
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 experiences some seasonal variation over the course of the year. The brighter period of the year lasts for 2.3 months, from June 28 to September 6, with an average daily incident shortwave energy per square meter above 5.8 kWh. The brightest day of the year is July 19, with an average of 6.0 kWh. The darker period of the year lasts for 1.5 months, from October 13 to November 27, with an average daily incident shortwave energy per square meter below 5.2 kWh. The darkest day of the year is November 2, with an average of 5.0 kWh. Average Daily Incident Shortwave Solar Energy
The average daily shortwave solar energy reaching the ground per square meter (orange line), with 25th to 75th and 10th to 90th percentile bands.

Data SourcesThis report illustrates the typical weather in Bushenyi, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Temperature and Dew PointThere is only a single weather station, Kigali International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Bushenyi. At a distance of 159 kilometers from Bushenyi, further than our threshold of 150 kilometers, this station is deemed insufficiently nearby to be relied upon as our primary source for temperature and dew point records. Consequently, the station records are blended with interpolated values from NASA's MERRA-2 satellite-era reanalysis , and both are corrected for elevation differences according to the International Standard Atmosphere . The weight assigned to the MERRA-2 value depends on the distance from Bushenyi to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 16%, making the weight assigned to the weather station 84%. Other DataAll 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. Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
