South Georgia and the South Sandwich Islands Barometric Pressure Map

Depending on how many places we monitor in South Georgia and the South Sandwich Islands, 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

Storms from the Southern Ocean often reach South Georgia and the South Sandwich Islands. These storms are called low-pressure systems. They bring strong winds, cloud cover, and rain or snow. In between storms, high-pressure systems might pass by, bringing clearer weather and calmer winds.

Geography

The islands are small and mountainous. When moist, cold air hits the mountains, it rises and the pressure drops even lower on the windward side. On the other side of the islands, the wind is drier and there may be slightly higher pressure. The ocean surrounding the islands helps keep the pressure from changing too quickly.

Seasonal Cycles

In summer, around December to February, the pressure tends to be a little higher, with fewer storms. In winter, from June to August, low-pressure systems are stronger and more common, making the weather stormier. The changes follow patterns linked to the shifting position of the westerly winds and ocean currents.

Climate Change

Climate change is making some weather systems stronger and shifting wind patterns. Scientists see a small drop in average air pressure and more frequent intense low-pressure systems in this area. This can mean stormier weather and faster winds around the islands.
