PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Zhonghe, the chance of a wet day over the course of July is gradually increasing, starting the month at 40% and ending it at 42%. For reference, the year's highest daily chance of a wet day is 44% on July 9, and its lowest chance is 1% on February 1. 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 July in Zhonghe is increasing, starting the month at 4.2 inches, when it rarely exceeds 6.8 inches or falls below 2.0 inches, and ending the month at 5.0 inches, when it rarely exceeds 7.9 inches or falls below 2.3 inches. The highest average 31-day accumulation is 5.1 inches on July 23. SunOver the course of July in Zhonghe, the length of the day is decreasing. From the start to the end of the month, the length of the day decreases by 51 minutes, implying an average daily decrease of 1 minute, 41 seconds, and weekly decrease of 11 minutes, 49 seconds. The shortest day of the month is July 31, with 14 hours, 47 minutes of daylight and the longest day is July 1, with 15 hours, 37 minutes of daylight. The earliest sunrise of the month in Zhonghe is 3:40 AM on July 1 and the latest sunrise is 28 minutes later at 4:07 AM on July 31. The latest sunset is 7:17 PM on July 1 and the earliest sunset is 23 minutes earlier at 6:54 PM on July 31. Daylight saving time is not observed in Zhonghe during 2024. For reference, on June 20, the longest day of the year, the Sun rises at 3:35 AM and sets 15 hours, 41 minutes later, at 7:17 PM, while on December 21, the shortest day of the year, it rises at 7:01 AM and sets 8 hours, 42 minutes later, at 3:44 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 July 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 Zhonghe is very rapidly increasing during July, rising from 18% to 50% over the course of the month. The highest chance of a muggy day during July is 50% on July 31. For reference, on July 31, the muggiest day of the year, there are muggy conditions 50% of the time, while on January 1, 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 Zhonghe is essentially constant during July, remaining around 4.9 miles per hour throughout. For reference, on March 25, the windiest day of the year, the daily average wind speed is 8.2 miles per hour, while on August 8, the calmest day of the year, the daily average wind speed is 4.8 miles per hour. The hourly average wind direction in Zhonghe throughout July is predominantly from the south, with a peak proportion of 43% on July 12. 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). The growing season in Zhonghe typically lasts for 5.2 months (158 days), from around April 26 to around October 1, rarely starting before April 11 or after May 12, and rarely ending before September 17 or after October 16. The month of July in Zhonghe is reliably fully within the growing season. 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 Zhonghe are rapidly increasing during July, increasing by 670°F, from 918°F to 1,588°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 Zhonghe is gradually decreasing during July, falling by 0.6 kWh, from 6.3 kWh to 5.7 kWh, over the course of the month.

Data SourcesThis report illustrates the typical weather in Zhonghe, 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, Harbin Taiping International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Zhonghe. At a distance of 197 kilometers from Zhonghe, 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 Zhonghe to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 48%, making the weight assigned to the weather station 52%. 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.
