Accurately get real-time sea-level barometric pressure for major Chinese cities, with data sourced from the National Meteorological Information Center.
Check current atmospheric pressure, along with wind speed, temperature, and weather conditions.
Enter a city to view current atmospheric pressure.
When you need to know the atmospheric pressure of a specific location, authoritative real-time data is often hard to find. By connecting to the National Meteorological Information Center's API, this tool provides hourly updated sea-level pressure (hPa) for prefecture-level and provincial capital cities across China. Sea-level pressure is the station's measured pressure adjusted to sea level using a standard atmospheric model. This eliminates the impact of altitude differences, making it a crucial metric for weather analysis and health assessments.
Q: Why does the pressure value show as "Delayed" for some cities?
During extreme weather events (such as a typhoon landfall), some stations may experience brief reporting outages. In these cases, the system displays the most recent valid value and marks it as "Delayed".
Q: What is the special significance of 1013.25 hPa?
This is the baseline value for the international Mean Sea Level Pressure (MSLP), commonly used as a reference standard for high and low atmospheric pressure.
Please use standard city names (e.g., "西安" instead of "陕西省西安市"). The barometric pressure values are adjusted to sea level and cannot be used directly for altitude calculations. Query results are for reference only; during extreme weather, please rely on official warnings from local meteorological departments.
Barometric pressure differences are primarily influenced by weather systems (such as high-pressure ridges or low-pressure troughs). Pressure differences between cities within the same province can reach 10-15 hPa. A typical example: The pressure difference between Beijing (1012.4 hPa) and Shijiazhuang (1015.2 hPa) at 14:00 on June 15, 2024, was 2.8 hPa, reflecting the pressure gradient distribution in North China at that time.
