Precipitation

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in China varies significantly throughout the year.

The wetter season lasts 5.1 months, from May 7 to October 11, with a greater than 22% chance of a given day being a wet day. The chance of a wet day peaks at 38% on September 12.

The drier season lasts 6.9 months, from October 11 to May 7. The smallest chance of a wet day is 6% on December 11.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 38% on September 12.

The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. The transitions to and from daylight saving time are indicated by the 'DST' labels.

Humidity

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.

China experiences extreme seasonal variation in the perceived humidity.

The muggier period of the year lasts for 7.8 months, from March 22 to November 14, during which time the comfort level is muggy, oppressive, or miserable at least 25% of the time. The muggiest day of the year is June 18, with muggy conditions 91% of the time.

The least muggy day of the year is January 22, with muggy conditions 4% of the time.

Wind

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 China experiences significant seasonal variation over the course of the year.

The windier part of the year lasts for 5.4 months, from March 9 to August 21, with average wind speeds of more than 10.5 miles per hour. The windiest day of the year is July 13, with an average hourly wind speed of 12.8 miles per hour.

The calmer time of year lasts for 6.6 months, from August 21 to March 9. The calmest day of the year is December 16, with an average hourly wind speed of 8.2 miles per hour.

Best Time of Year to Visit

To characterize how pleasant the weather is in China 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 China for general outdoor tourist activities are from late February to mid May and from early October to late November, with a peak score in the last week of October.

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.

Growing Season

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).

Temperatures in China are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year.

Within 10 miles also contains only modest variations in elevation (348 feet). Within 50 miles contains only modest variations in elevation (4,882 feet).

The area within 2 miles of China is covered by cropland (76%), shrubs (12%), and artificial surfaces (10%), within 10 miles by cropland (56%) and shrubs (29%), and within 50 miles by cropland (60%) and shrubs (33%).

Data Sources

This report illustrates the typical weather in China, 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 are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in China.

For each station, the records are corrected for the elevation difference between that station and China according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

The estimated value at China is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between China and a given station.

The stations contributing to this reconstruction are: General Mariano Escobedo International Airport (44%, 88 kilometers, west); McAllen Miller International Airport (32%, 112 kilometers, northeast); and Zapata County Airport (23%, 141 kilometers, north).

Other Data

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.

Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database .

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.
