The figure below presents a compact representation of key lunar data for 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.

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.

Chaoyang experiences extreme seasonal variation in the perceived humidity.

The muggier period of the year lasts for 2.0 months, from June 28 to August 27, during which time the comfort level is muggy, oppressive, or miserable at least 13% of the time. The month with the most muggy days in Chaoyang is July, with 11.7 days that are muggy or worse.

The least muggy day of the year is March 16, 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 Chaoyang experiences significant seasonal variation over the course of the year.

The windier part of the year lasts for 4.7 months, from January 13 to June 4, with average wind speeds of more than 10.2 miles per hour. The windiest month of the year in Chaoyang is April, with an average hourly wind speed of 12.4 miles per hour.

The calmer time of year lasts for 7.3 months, from June 4 to January 13. The calmest month of the year in Chaoyang is August, with an average hourly wind speed of 7.8 miles per hour.

To characterize how pleasant the weather is in Chaoyang 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 time of year to visit Chaoyang for general outdoor tourist activities is from early June to early September, with a peak score in the third week of August.

The beach/pool score favors clear, rainless days with perceived temperatures between 75°F and 90°F. Based on this score, the best time of year to visit Chaoyang for hot-weather activities is from early July to mid August, with a peak score in the last week of July.

Methodology

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 Chaoyang typically lasts for 6.0 months (182 days), from around April 16 to around October 15, rarely starting before March 31 or after May 2, and rarely ending before October 1 or after October 28.

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 Chaoyang should appear around April 14, only rarely appearing before April 5 or after April 23.

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 3.5 months, from April 13 to July 29, with an average daily incident shortwave energy per square meter above 5.9 kWh. The brightest month of the year in Chaoyang is May, with an average of 6.6 kWh.

The darker period of the year lasts for 3.0 months, from November 1 to February 3, with an average daily incident shortwave energy per square meter below 3.1 kWh. The darkest month of the year in Chaoyang is December, with an average of 2.3 kWh.
