When you need to adjust your travel plans or moisture-proofing measures based on air humidity, accurate real-time data is crucial. This tool retrieves the relative humidity (RH%) of 339 prefecture-level cities in China via a national meteorological API. This value represents the percentage of water vapor currently in the air compared to the maximum possible amount at the same temperature, directly affecting human comfort and item storage conditions. Typical output includes: city name, data update time, humidity percentage, and a comfort indicator.
Q: Why can't I find data for county-level cities?
A: This tool only supports prefecture-level administrative divisions. To check a county-level city (like Kunshan), you need to enter the name of its governing prefecture-level city (Suzhou).
Q: What does a relative humidity of 80% mean?
A: When the RH value exceeds 70%, it enters the humid range. At 80% humidity: ① Human sweat is difficult to evaporate, making the perceived temperature 3-5°C higher than the actual temperature. ② It is recommended to turn on moisture-proof modes for electronic devices. ③ Food storage facilities need to strengthen dehumidification measures.
Please use the standard city names registered by the Ministry of Civil Affairs (e.g., "Urumqi" instead of abbreviations). The humidity values are observation data from meteorological stations; for indoor environments, it is recommended to use local sensors. If there is a network error, a "No data available" prompt will appear.
Relative humidity fluctuates with temperature changes, so it is recommended to check once in the morning and once in the evening to get the diurnal range. Typical scenario examples: ① Calligraphy and painting preservation should maintain 45-55% RH. ② Asthma patients should avoid traveling to areas with >75% RH. ③ Electronics factories need to control humidity at 40-60% RH. Querying "Shanghai" and "Lhasa" allows you to compare the humidity differences between coastal and plateau cities.
