Today's low pressure
What is Barometric Pressure
Barometric pressure, also called atmospheric pressure, is the weight of the air pressing down on the Earth. Think of it like a giant ocean of air above us. Even though air seems light, the weight of all that air adds up and pushes on everything, including the ground, your body, and even buildings.
Changes in barometric pressure are often linked to changes in the weather. High pressure usually means clear skies and calm weather, while low pressure often brings clouds, rain, and sometimes storms.
Some people and animals can sense changes in barometric pressure. For example, a drop in pressure before a storm can sometimes cause headaches, joint pain, or make people feel tired. Recent research even suggests that the inner ear, which helps us balance, may be able to detect pressure changes. However, not everyone feels these effects, and some people are more sensitive than others.
Barometric pressure is measured with a barometer. The most common units are inches of mercury (inHg) or millibars (mb). At sea level, the standard atmospheric pressure is typically about 1013.25 mb or 29.92 inHg.
Barometric pressure can also be used to figure out altitude. Lower pressure usually means you are higher up (like on a mountain), while higher pressure means you are closer to sea level. This can be helpful for navigation, especially in places where GPS might not work well.
Overall, atmospheric pressure plays an important role in both the weather and the health and well-being of living things on Earth. That is why it is so useful to monitor and understand.
Pressure fluctuations
(Data above represents the highest/lowest recorded pressure in our monitored cities for today.)High and low readings
What are high and low barometric pressures? Barometric pressure above 1023 hPa (30.2 inHg) is considered high pressure, while below 1009 hPa (29.8 inHg) is considered low.
In most places where people live, the barometric pressure stays within the normal range of 1009 to 1023 hPa (29.8 to 30.2 inHg).
The global average barometric pressure at sea level is about 1013.25 hectopascals (hPa), or 29.92 inches of mercury (inHg). This is often called one standard atmosphere (atm) of pressure.
Keep in mind that barometric pressure can change depending on your location and the weather.
- High Pressure: above 1023 hPa (30.2 inHg)
- Normal Range: 1009-1023 hPa (29.8-30.2 inHg)
- Low Pressure: below 1009 hPa (29.8 inHg)
The highest sea-level adjusted pressure ever recorded on Earth is 1083.8 hPa (32.0 inHg) in Agata, Siberia, on December 31, 1968. The lowest was 870 hPa (25.69 inHg) in the eye of Typhoon Tip in 1979. These extreme values show just how much the atmosphere can change.

Barometric Pressure Forecast
Barometric pressure, or atmospheric pressure, plays a key role in weather patterns and even how we feel. A rising pressure often means clear skies, while a rapid drop can signal storms ahead.

Barometric Pressure Headaches
Have you ever noticed a headache when the weather is about to change? Changes in barometric pressure can cause headaches in some people. It's like the air pushing differently on your body can trigger a headache.
When the pressure drops quickly, like before a storm, some people experience migraines. Recent research has found that rapid pressure changes are more likely to increase the number of migraines someone gets, rather than making each headache more painful or longer. Scientists are even studying how the inner ear might detect these pressure changes and send signals to the brain.
However, not everyone is affected by changes in barometric pressure, and there can be other factors that cause headaches as well.
Barometric Pressure During a Hurricane
Barometric pressure in a hurricane tells us how strong or weak the storm is. When the pressure is low, the hurricane is intense, and when it's high, the storm is weaker.
Normally, the air pressure at sea level on a calm day is around 1013.2 millibars. But during a hurricane, at the center called the eye, the pressure can drop a lot, sometimes below 900 millibars.
This means the air in the eye is lighter than the air around it, creating a big difference in pressure. This causes air to rush from high to low pressure, making strong winds and thunderstorms.
Hurricane Wilma, Gilbert, and Rita
For example, in Hurricane Wilma in 2005, the pressure dropped to 882 millibars, the lowest ever recorded in the Atlantic.
Other powerful hurricanes with low pressures include Hurricane Gilbert (888 millibars) in 1988, the Labor Day Hurricane (892 millibars) in 1935, and Hurricane Rita (895 millibars) in 2005.
These storms were all extremely destructive and reached Category 5, the highest level on the hurricane intensity scale.
