Christmas Island Barometric Pressure Map

Depending on how many places we monitor in Christmas Island, 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

Air pressure on Christmas Island often changes because of weather systems like the monsoon. The Australian summer monsoon lowers air pressure, bringing clouds and rain. The trade winds and, less often, tropical systems can also affect air pressure, changing the island’s weather quickly.

Geography

Christmas Island is a small, high island in the Indian Ocean. Its location near the equator means pressure doesn’t change as much as it does in places farther from the equator. The ocean surrounding it helps keep air pressure steady, except when strong weather systems pass by.

Seasonal Cycles

During the wet season, from November to April, low-pressure systems from the monsoon move in, making the air pressure drop. In the dry season, from May to October, higher pressure from trade wind systems makes the weather calmer and air pressure higher. These pressure changes follow a yearly pattern linked to the monsoon cycle.

Climate Change

Climate change may be making the pressure patterns less predictable. Some years, the wet season comes later or storms are stronger, changing usual pressure trends. Rising ocean temperatures could also affect winds and when pressure drops or rises, making Christmas Island’s weather patterns shift slowly over time.
