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

Saint Pierre and Miquelon’s air pressure changes with passing weather systems. Low-pressure systems often arrive from the Atlantic, bringing clouds and wind. High-pressure systems usually come from the north or west, bringing clear skies. The islands get many storms like Nor’easters, which quickly lower air pressure.

Geography

The islands are small and surrounded by the cold Atlantic Ocean. The ocean keeps temperatures and air pressure more stable than large land areas. Wind from the sea can bring rapid pressure changes, especially during storms. The nearby Canadian mainland can block some weather systems, but most storms come straight over the ocean.

Seasonal Cycles

In winter, low-pressure systems are more common and strong, leading to stormy weather. In summer, high pressure is more frequent, keeping weather calmer. Spring and autumn are times when air pressure changes quickly, with storms and calm spells trading places often.

Climate Change

Climate change is making these pressure patterns less predictable. Some studies show that storms are becoming stronger and more frequent, causing more drops in air pressure. Warmer ocean water may also affect how and when high- or low-pressure systems reach Saint Pierre and Miquelon.
