Sunrise & Sunset with Twilight
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.
Yanggu experiences extreme seasonal variation in the perceived humidity.
The muggier period of the year lasts for 3.1 months, from June 10 to September 14, during which time the comfort level is muggy, oppressive, or miserable at least 23% of the time. The muggiest day of the year is July 27, with muggy conditions 92% of the time.
The least muggy day of the year is February 15, when muggy conditions are essentially unheard of.

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 Yanggu experiences significant seasonal variation over the course of the year.
The windier part of the year lasts for 4.1 months, from February 15 to June 19, with average wind speeds of more than 8.5 miles per hour. The windiest day of the year is April 26, with an average hourly wind speed of 10.4 miles per hour.
The calmer time of year lasts for 7.9 months, from June 19 to February 15. The calmest day of the year is August 29, with an average hourly wind speed of 6.6 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Yanggu varies throughout the year.
The wind is most often from the south for 10 months, from January 27 to November 28, with a peak percentage of 58% on June 18. The wind is most often from the north for 2.0 months, from November 28 to January 27, with a peak percentage of 38% on January 1.
Best Time of Year to Visit
To characterize how pleasant the weather is in Yanggu throughout the year, we compute two travel scores.
The tourism score favors clear, rainless days with perceived temperatures between 65°F and 80°F. Based on this score, the best times of year to visit Yanggu for general outdoor tourist activities are from early May to early June and from late August to early October, with a peak score in the third week of September.
The beach/pool score favors clear, rainless days with perceived temperatures between 75°F and 90°F. Based on this score, the best times of year to visit Yanggu for hot-weather activities are from late May to mid July and from late July to early September, with a peak score in the third week of June.
For each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation. Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed.
Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies.
Our precipitation score, which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0.04 inches of precipitation or more.
Our tourism temperature score is 0 for perceived temperatures below 50°F, rising linearly to 9 for 65°F, to 10 for 75°F, falling linearly to 9 for 80°F, and to 1 for 90°F or hotter.
Our beach/pool temperature score is 0 for perceived temperatures below 65°F, rising linearly to 9 for 75°F, to 10 for 82°F, falling linearly to 9 for 90°F, and to 1 for 100°F or hotter.
Definitions 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 Yanggu typically lasts for 8.2 months (250 days), from around March 12 to around November 17, rarely starting before February 23 or after March 30, and rarely ending before November 1 or after December 3.
Time Spent in Various Temperature Bands and 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.
Based on growing degree days alone, the first spring blooms in Yanggu should appear around March 20, only rarely appearing before March 11 or after April 1.

This 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 experiences significant seasonal variation over the course of the year.
The brighter period of the year lasts for 4.0 months, from April 11 to August 11, with an average daily incident shortwave energy per square meter above 5.7 kWh. The brightest day of the year is May 30, with an average of 6.5 kWh.
The darker period of the year lasts for 3.1 months, from November 1 to February 6, with an average daily incident shortwave energy per square meter below 3.3 kWh. The darkest day of the year is December 22, with an average of 2.5 kWh.

Temperature and Dew Point
There is only a single weather station, Jinan, in our network suitable to be used as a proxy for the historical temperature and dew point records of Yanggu.
At a distance of 126 kilometers from Yanggu, 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 Yanggu 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.
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.
