Samoa Barometric Pressure Map
Depending on how many places we monitor in Samoa, 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
Air pressure in Samoa changes because of weather systems like the South Pacific Convergence Zone and tropical cyclones. These systems bring periods of high and low pressure. High pressure usually means good weather, while low pressure can bring storms or rain.
Geography
Samoa is made of islands with mountains and surrounded by ocean. Mountains can block or channel winds, causing different air pressures in different places on the islands. The ocean keeps temperatures steady, so air pressure doesn’t change as quickly as it might on landlocked areas.
Seasonal Cycles
During the wet season from November to April, air pressure is often lower because warmer air rises and brings more rain. In the dry season from May to October, there is usually higher air pressure with cooler, drier air coming from the southeast.
Climate Change
Climate change is warming the ocean and atmosphere, which affects air pressure patterns in Samoa. Warmer seas can cause lower pressure and stronger storms. Air pressure may become less steady, leading to more intense cyclones or changing rainfall patterns.
Places in Samoa
You can find your city in the lists below, by using our search, or on the Samoa Pressure Map above. We're tracking barometric pressure across multiple locations in Samoa to keep you informed.
Each city includes a pressure status showing whether it's currently high, normal or low, along with two volatility values: one for today and one for the full period, usually 14 days. These help you see how much the pressure is changing over time.
