PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Buikwe varies very significantly throughout the year. The wetter season lasts 9.2 months, from August 23 to May 28, with a greater than 59% chance of a given day being a wet day. The chance of a wet day peaks at 84% on April 23. The drier season lasts 2.8 months, from May 28 to August 23. The smallest chance of a wet day is 33% on July 3.

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. Buikwe experiences extreme seasonal variation in the perceived humidity. The muggier period of the year lasts for 9.5 months, from September 8 to June 24, during which time the comfort level is muggy, oppressive, or miserable at least 48% of the time. The muggiest day of the year is May 2, with muggy conditions 92% of the time. The least muggy day of the year is July 20, with muggy conditions 33% of the time. 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 Buikwe does not vary significantly over the course of the year, remaining within 0.5 miles per hour of 2.8 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 Buikwe varies throughout the year. The wind is most often from the south for 8.2 months, from January 20 to September 26, with a peak percentage of 72% on June 25. The wind is most often from the west for 1.2 months, from September 26 to November 3, with a peak percentage of 31% on October 9. The wind is most often from the east for 2.5 months, from November 3 to January 20, with a peak percentage of 38% 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 January 5 to March 13, with an average daily incident shortwave energy per square meter above 6.1 kWh. The brightest day of the year is February 10, with an average of 6.6 kWh. The darker period of the year lasts for 1.2 months, from April 16 to May 23, with an average daily incident shortwave energy per square meter below 4.9 kWh. The darkest day of the year is May 3, with an average of 4.5 kWh. Average Daily Incident Shortwave Solar Energy

Data SourcesThis report illustrates the typical weather in Buikwe, 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 are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Buikwe. For each station, the records are corrected for the elevation difference between that station and Buikwe 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 Buikwe is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Buikwe and a given station. The stations contributing to this reconstruction are: Entebbe Airport (70%, 71 kilometers, southwest); Kisumu Airport (15%, 197 kilometers, east); and Kakamega Airport (15%, 198 kilometers, east). 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.
