Compare two pressure readings to see whether barometric pressure is rising, falling, or steady. Pressure trends can help indicate changing weather conditions.
Common Pressure Trend Signals
Rising
Often more stable weather
Falling
Often unsettled weather
Rapid Rise
Quick weather improvement
Rapid Fall
Stronger weather change possible
Example Pressure Changes
1008 → 1013
Rising by 5 hPa
1002 → 998
Falling by 4 hPa
1012 → 1012
Steady pressure

About Pressure Trends
Pressure trend refers to how atmospheric pressure changes over time. Rising pressure is often linked to improving or more stable weather, while falling pressure is often associated with unsettled weather or incoming systems.
This tool compares two pressure readings and shows the difference, making it easier to understand whether conditions are becoming more stable or less stable.
