Solar Elevation on June 4, 2020
We 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.
In Gaotun on June 4, the chance of muggy conditions does not change significantly over the course of the day, remaining around 3% throughout.

This 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 Gaotun on June 4 varies throughout the day, with a daily average of 9.8 miles per hour.
The windiest time of day is around 2:15 PM, with an average hourly wind speed of 12.1 miles per hour, mostly staying between 8.6 miles per hour and 15.5 miles per hour, and rarely falling below 5.5 miles per hour or exceeding 18.5 miles per hour.
The calmest time of day is around 7:45 PM, with an average hourly wind speed of 8.0 miles per hour, mostly staying between 5.3 miles per hour and 10.1 miles per hour, and rarely falling below 3.8 miles per hour or exceeding 13.4 miles per hour.
For reference, on April 14, the windiest day of the year, the daily average wind speed is 12.1 miles per hour, while on August 24, the calmest day of the year, the daily average wind speed is 7.5 miles per hour.
Wind Speed on June 4
Over the entire course of June 4 in Gaotun, the hourly average wind direction, in order of prevalence, is from the south (52%), west (24%), north (17%), and east (8%).
Wind Direction on June 4
Gaotun 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 does not change appreciably over the course of the day, so this section does not include a chart.
The average surface water temperature on June 4 in Gaotun is 61°F, mostly staying between 59°F and 63°F, and rarely falling below 57°F or exceeding 66°F.
For reference, the year's highest average is 78°F on August 10, and its lowest average is 31°F on February 12.
Shortwave Solar Power
This section discusses the incident shortwave solar power 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 peak incident shortwave solar power per square meter is 0.79 kilowatts at around 12:00 PM.
In contrast, the corresponding value on May 28, the brightest day of the year, is 0.79 kilowatts at around 10:45 AM. The corresponding value on December 18, the darkest day of the year, is 0.39 kilowatts at around 10:45 AM.

This report illustrates the typical weather in Gaotun, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There is only a single weather station, Shenyang Taoxian International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Gaotun.
At a distance of 153 kilometers from Gaotun, 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 Gaotun to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 6%, making the weight assigned to the weather station 94%.
All 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.

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.
