Hong Kong Barometric Pressure Map

Depending on how many places we monitor in Hong Kong, the map displays a sampled set of barometric pressure data to give a clear overview of current conditions.

Here you can see which cities experienced the biggest and smallest changes in barometric pressure today. This helps highlight areas with the most stable or unstable weather patterns.

Most volatile

Least volatile

How is it calculated?

Our volatility “beta” number is generated by an algorithm that analyzes hourly barometric pressure changes. It looks at how much the pressure fluctuates from hour to hour. A beta of 0 means no change, perfectly stable pressure. The higher the decimal value, the more variation there has been throughout the day or over a longer period.

Weather Systems

Typhoons, cold fronts, and the monsoon are the main weather systems that change air pressure in Hong Kong. Typhoons bring very low air pressure, while cold fronts and the northeast monsoon usually raise pressure as cool, dry air arrives from the north.

Geography

Hong Kong is on the coast and near hills. So, moist sea air bumps into the land and hills, causing uneven air pressure. Pressure is often higher inland and lower by the sea. The hills can block or slow air, changing pressure patterns.

Seasonal Cycles

In winter, strong north winds from China make the air pressure high in Hong Kong. In summer, southerly winds from the sea bring hot, humid weather and lower pressure. Spring and autumn have shifting patterns as these winds change.

Climate Change

Climate change can make air pressure patterns in Hong Kong less steady. Warmer oceans may create stronger storms and more sudden pressure drops. Changing global winds could also affect the timing and strength of the monsoon, making pressure cycles less predictable.

Places in Hong Kong

You can find your city in the lists below, by using our search, or on the Hong Kong Pressure Map above. We're tracking barometric pressure across multiple locations in Hong Kong to keep you informed.

Each city includes a pressure status showing whether it's currently high, normal or low, along with two volatility values: one for today and one for the full period, usually 14 days. These help you see how much the pressure is changing over time.
