Dominica Barometric Pressure Map
Depending on how many places we monitor in Dominica, the map displays a sampled set of barometric pressure data to give a clear overview of current conditions.Trends Today
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.
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 waves, trade winds, and hurricanes are the main weather systems that change air pressure in Dominica. Tropical waves and hurricanes bring low pressure, causing storms and heavy rain. Trade winds usually bring higher pressure and keep the weather steady and breezy most of the year.
Geography
Dominica has mountains and valleys that change how air pressure spreads across the island. The higher mountains have lower air pressure than the coastal areas. Valleys sometimes trap cooler air, making the pressure there slightly higher, especially at night.
Seasonal Cycles
Pressure in Dominica shifts with the seasons. During the wet season from June to November, low-pressure systems and hurricanes are more common. In the dry season from December to May, higher pressure is usual, so the weather is calmer and drier.
Climate Change
Climate change is causing warmer temperatures and can shift pressure patterns in Dominica. Stronger heat means more evaporation and more intense storms with lower pressure. Hurricanes and unusual weather patterns may become more frequent, making pressure changes less predictable.
