- Saint Helier: 0.52
Least volatile
- Saint Helier: 0.52
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
Weather systems like low-pressure storms and high-pressure ridges often pass over Jersey. Low pressure usually brings clouds and rain, while high pressure usually brings calm, clear weather. Atlantic storms frequently move in from the west, affecting Jersey’s pressure patterns throughout the year.
Geography
Jersey is an island surrounded by water, which helps moderate air pressure changes. The English Channel keeps sudden shifts less extreme by balancing temperatures. Jersey’s flat land means local pressure stays fairly uniform, so big differences between places on the island are rare.
Seasonal Cycles
In winter, strong low-pressure systems are more common, so the weather is often windy and unsettled. Summer usually brings higher pressure, leading to more sunshine and quieter weather. Spring and autumn show more mixed pressure as the island shifts between the colder and warmer seasons.
Climate Change
Climate change may cause pressure patterns to shift over time. As the air and sea warm, storms might grow stronger or arrive more often, leading to bigger swings between high and low pressure. This could mean more unusual weather for Jersey in the future.
