Daily low temperatures decrease by 20°F, from 72°F to 52°F, rarely falling below 43°F or exceeding 75°F. For reference, on July 20, the hottest day of the year, temperatures in Baishi typically range from 74°F to 87°F, while on January 19, the coldest day of the year, they range from 46°F to 63°F. The figure below shows you a compact characterization of the hourly average fall temperatures. The horizontal axis is the day, the vertical axis is the hour of the day, and the color is the average temperature for that hour and day. Dulac, United States (8,588 miles away) and Jacksonville, United States (8,709 miles) are the far-away foreign places with temperatures most similar to Baishi (view comparison). CloudsThe fall in Baishi experiences very rapidly decreasing cloud cover, with the percentage of time that the sky is overcast or mostly cloudy decreasing from 75% to 28%. The clearest day of the fall is November 30, with clear, mostly clear, or partly cloudy conditions 72% of the time. For reference, on June 11, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 87%, while on December 12, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 74%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Baishi, the chance of a wet day over the course of the fall is very rapidly decreasing, starting the season at 47% and ending it at 10%. For reference, the year's highest daily chance of a wet day is 61% on June 2, and its lowest chance is 7% on December 18. 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 fall in Baishi is very rapidly decreasing, starting the season at 6.7 inches, when it rarely exceeds 10.7 inches or falls below 3.3 inches, and ending the season at 1.1 inches, when it rarely exceeds 3.3 inches. SunOver the course of the fall in Baishi, the length of the day is rapidly decreasing. From the start to the end of the season, the length of the day decreases by 1 hour, 41 minutes, implying an average daily decrease of 1 minute, 8 seconds, and weekly decrease of 7 minutes, 53 seconds. The shortest day of the fall is November 30, with 10 hours, 53 minutes of daylight and the longest day is September 1, with 12 hours, 34 minutes of daylight. The earliest sunrise of the fall in Baishi is 4:18 AM on September 1 and the latest sunrise is 40 minutes later at 4:57 AM on November 30. The latest sunset is 4:52 PM on September 1 and the earliest sunset is 1 hour, 2 minutes earlier at 3:50 PM on November 27. Daylight saving time is not observed in Baishi during 2024. For reference, on June 20, the longest day of the year, the Sun rises at 3:52 AM and sets 13 hours, 30 minutes later, at 5:22 PM, while on December 21, the shortest day of the year, it rises at 5:10 AM and sets 10 hours, 46 minutes later, at 3:56 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 fall 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 Baishi is very rapidly decreasing during the fall, falling from 97% to 7% over the course of the season. For reference, on June 30, the muggiest day of the year, there are muggy conditions 100% of the time, while on January 8, the least muggy day of the year, there are muggy conditions 1% 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 Baishi is increasing during the fall, increasing from 6.4 miles per hour to 8.3 miles per hour over the course of the season. For reference, on March 27, the windiest day of the year, the daily average wind speed is 9.2 miles per hour, while on August 19, the calmest day of the year, the daily average wind speed is 6.2 miles per hour. The highest daily average wind speed during the fall is 8.3 miles per hour on November 30. The wind direction in Baishi during the fall is predominantly out of the east from September 1 to November 29 and the north from November 29 to November 30. Water TemperatureBaishi 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 Baishi is very rapidly decreasing during the fall, falling by 11°F, from 84°F to 73°F, over the course of the season. 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). While it does not do so every year, freezing temperatures are seen in Baishi over some winters. The day least likely to be in the growing season is January 12, with a 66% chance. 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 Baishi are very rapidly increasing during the fall, increasing by 1,886°F, from 4,939°F to 6,826°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 Baishi is decreasing during the fall, falling by 1.0 kWh, from 5.3 kWh to 4.3 kWh, over the course of the season. The highest average daily incident shortwave solar energy during the fall is 5.4 kWh on September 25.

Data SourcesThis report illustrates the typical weather in Baishi, 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, Zhanjiang Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Baishi. At a distance of 146 kilometers from Baishi, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records. The station records are corrected for the elevation difference between the station and Baishi according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis. 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.
