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
Tropical weather systems, like trade winds and hurricanes, strongly influence air pressure in Saint Martin. High pressure usually brings calm, sunny weather, while low pressure is linked to storms and heavy rain. When hurricanes pass nearby, air pressure drops sharply, causing intense winds and rough seas.
Geography
Saint Martin’s hilly terrain changes how air moves across the island. Hills can block or redirect winds, causing small differences in air pressure from one side to the other. The island is surrounded by sea, which helps keep overall air pressure more stable compared to mainland areas.
Seasonal Cycles
In the dry winter season, higher air pressure dominates due to cool, stable air from the north. During the wet summer and fall, pressure is lower, making it easier for storms and hurricanes to form and pass through. These seasonal changes repeat each year.
Climate Change
Climate change affects air pressure by warming the ocean and atmosphere. This makes strong storms with very low pressure more likely. Changing wind patterns can also shift when and where high or low pressure happens, leading to new weather extremes for Saint Martin.
