Cities with the Lowest Average Pressure Today

The following list ranks our tracked cities by the lowest average barometric pressure today. This is determined by taking the average of all the pressure readings forecasted for each hour within the 24-hour period starting and ending at midnight, UTC−08:00 (Pacific Standard Time) in each city. Cities with low pressure tend to be experiencing more stormy weather, wind, or precipitation. Events such as hurricanes or polar vortexes can push barometric pressures even lower.

Adjusted to sea level, barometric pressures below 29.8 inHg are considered to be high and pressures above 29.4 inHg are considered to be very low.
