The clearest day of the month is June 30, with clear, mostly clear, or partly cloudy conditions 62% of the time. For reference, on March 15, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 75%, while on August 31, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 72%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Mwanga, the chance of a wet day over the course of June is very rapidly decreasing, starting the month at 24% and ending it at 11%. For reference, the year's highest daily chance of a wet day is 62% on April 19, and its lowest chance is 8% on August 27. RainfallTo 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 June in Mwanga is rapidly decreasing, starting the month at 2.1 inches, when it rarely exceeds 4.2 inches or falls below 0.3 inches, and ending the month at 0.9 inches, when it rarely exceeds 2.5 inches. SunOver the course of June in Mwanga, the length of the day is essentially constant. The shortest day of the month is June 21, with 11 hours, 51 minutes of daylight and the longest day is June 1, with 11 hours, 52 minutes of daylight. The earliest sunrise of the month in Mwanga is 6:29 AM on June 1 and the latest sunrise is 6 minutes later at 6:35 AM on June 30. The earliest sunset is 6:20 PM on June 1 and the latest sunset is 6 minutes later at 6:26 PM on June 30. Daylight saving time is not observed in Mwanga during 2024. For reference, on December 21, the longest day of the year, the Sun rises at 6:13 AM and sets 12 hours, 24 minutes later, at 6:37 PM, while on June 20, the shortest day of the year, it rises at 6:33 AM and sets 11 hours, 51 minutes later, at 6:24 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 June 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 Mwanga is very rapidly decreasing during June, falling from 55% to 14% over the course of the month. For reference, on April 17, the muggiest day of the year, there are muggy conditions 98% of the time, while on August 12, the least muggy day of the year, there are muggy conditions 5% 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 Mwanga is essentially constant during June, remaining within 0.2 miles per hour of 8.6 miles per hour throughout. For reference, on September 1, the windiest day of the year, the daily average wind speed is 9.3 miles per hour, while on March 25, the calmest day of the year, the daily average wind speed is 6.3 miles per hour. The hourly average wind direction in Mwanga throughout June is predominantly from the south, with a peak proportion of 92% on June 17. Water TemperatureMwanga is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water. The average surface water temperature in Mwanga is gradually decreasing during June, falling by 2°F, from 81°F to 79°F, over the course of the month. 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 Mwanga 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 Mwanga are rapidly increasing during June, increasing by 626°F, from 8,669°F to 9,295°F, over the course of the month. 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 Mwanga is essentially constant during June, remaining around 5.9 kWh throughout. The lowest average daily incident shortwave solar energy during June is 5.9 kWh on June 28. TopographyFor the purposes of this report, the geographical coordinates of Mwanga are -4.800 deg latitude, 38.200 deg longitude, and 1,358 ft elevation.

Within 10 miles contains large variations in elevation (6,237 feet). Within 50 miles also contains extreme variations in elevation (7,966 feet). The area within 2 miles of Mwanga is covered by cropland (52%) and shrubs (33%), within 10 miles by shrubs (42%) and cropland (34%), and within 50 miles by shrubs (47%) and trees (22%). Data SourcesThis report illustrates the typical weather in Mwanga, 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 Mwanga. For each station, the records are corrected for the elevation difference between that station and Mwanga 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 Mwanga is computed as the weighted average of the individual contributions from each station, in addition to a contribution from the MERRA-2 reconstruction, corrected for the difference between the reference elevation of the MERRA-2 grid cell and the elevation of Mwanga. The station weights are proportional to the inverse of the distance between Mwanga and a given station. The weight assigned to the MERRA-2 value depends on the distance from Mwanga to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 18%. The stations contributing to this reconstruction are:
To get a sense of how much these sources agree with each other, you can view a comparison of Mwanga and the stations that contribute to our estimates of its temperature history and climate. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data. 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.
