PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Beira, the chance of a wet day over the course of the summer is increasing, starting the season at 41% and ending it at 46%. For reference, the year's highest daily chance of a wet day is 53% on January 29, and its lowest chance is 4% on September 11. 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 summer in Beira is rapidly increasing, starting the season at 3.9 inches, when it rarely exceeds 6.4 inches or falls below 1.3 inches, and ending the season at 5.2 inches, when it rarely exceeds 9.9 inches or falls below 1.4 inches. The highest average 31-day accumulation is 6.2 inches on January 28. SunOver the course of the summer in Beira, the length of the day is decreasing. From the start to the end of the season, the length of the day decreases by 45 minutes, implying an average daily decrease of 30 seconds, and weekly decrease of 3 minutes, 32 seconds. The shortest day of the summer is February 28, with 12 hours, 30 minutes of daylight and the longest day is December 21, with 13 hours, 20 minutes of daylight. The earliest sunrise of the summer in Beira is 4:52 AM on December 1 and the latest sunrise is 46 minutes later at 5:38 AM on February 28. The earliest sunset is 6:07 PM on December 1 and the latest sunset is 19 minutes later at 6:25 PM on January 16. Daylight saving time is not observed in Beira during 2024. For reference, on December 21, the longest day of the year, the Sun rises at 4:58 AM and sets 13 hours, 20 minutes later, at 6:18 PM, while on June 20, the shortest day of the year, it rises at 6:14 AM and sets 10 hours, 56 minutes later, at 5:10 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 summer 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 Beira is gradually increasing during the summer, rising from 95% to 99% over the course of the season. The highest chance of a muggy day during the summer is 100% on February 18. For reference, on February 5, the muggiest day of the year, there are muggy conditions 100% of the time, while on July 17, the least muggy day of the year, there are muggy conditions 26% 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 Beira is gradually decreasing during the summer, decreasing from 10.0 miles per hour to 9.2 miles per hour over the course of the season. For reference, on October 12, the windiest day of the year, the daily average wind speed is 11.3 miles per hour, while on June 7, the calmest day of the year, the daily average wind speed is 8.0 miles per hour. The wind direction in Beira during the summer is predominantly out of the east from December 1 to February 20 and the south from February 20 to February 28. Water TemperatureBeira 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 Beira is gradually increasing during the summer, rising by 2°F, from 82°F to 84°F, over the course of the season. The highest average surface water temperature during the summer is 85°F on February 2. 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 Beira 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 Beira are very rapidly increasing during the summer, increasing by 2,869°F, from 3,978°F to 6,847°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 Beira is gradually decreasing during the summer, falling by 0.5 kWh, from 7.1 kWh to 6.6 kWh, over the course of the season. TopographyFor the purposes of this report, the geographical coordinates of Beira are -19.844 deg latitude, 34.839 deg longitude, and 20 ft elevation.

Within 10 miles is essentially flat (171 feet). Within 50 miles contains only modest variations in elevation (679 feet). The area within 2 miles of Beira is covered by water (55%) and artificial surfaces (39%), within 10 miles by water (55%) and grassland (21%), and within 50 miles by water (51%) and grassland (25%). Data SourcesThis report illustrates the typical weather in Beira, 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, Chimoio, in our network suitable to be used as a proxy for the historical temperature and dew point records of Beira. At a distance of 167 kilometers from Beira, 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 Beira to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 25%, making the weight assigned to the weather station 75%. 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.
