The current value will be compared with the standard reference after it loads.
Live Tool
Barometric Pressure Today
Check current sea-level pressure for your city, compare it in hPa or inHg, and view a 7-day barometric pressure graph. The graph helps you see whether pressure is below, near, or above the standard reference today and whether the trend is starting to move.
Start with a city search or use your location to load current pressure and the next 7 days of forecast pressure.

7 Day Barometric Pressure Graph
7-Day Barometric Pressure Graph
This graph uses forecast sea-level pressure to show the direction of the next 7 days, not just one isolated number. A single reading matters less than the broader curve you can see over several days.
Is The Pressure High Today?
Is Barometric Pressure High Today?
Use today’s number as a reference, not a verdict. Standard sea-level pressure is 1013.25 hPa, approximately 29.92 inHg. This is a fixed reference, not your city’s measured average. High and low weather systems are relative to surrounding areas, so also check the trend and local forecast. Read our explanation of normal, high, and low barometric pressure.
Why Sea-Level Pressure
Compare cities and forecasts using the same frame.
Raw surface pressure changes with elevation. Sea-level pressure normalizes the reading so a city at altitude and a city near the coast can be compared more cleanly. That is why it is the better default for a “barometric pressure today” tool.
Read The Trend Better

Common questions about barometric pressure today
What counts as high barometric pressure today?
A reading above 1013.25 hPa is above the standard atmosphere reference, not necessarily above the average for your city or season. The labels here compare against that fixed reference; they do not identify weather systems or safety thresholds. Check the surrounding weather pattern and recent trend.
Why does this tool use sea-level pressure instead of raw pressure?
Sea-level pressure is normalized for elevation, which makes it more useful for comparing cities, forecasts, and weather maps. Raw surface pressure is still useful locally, but it is harder to compare between places.
Why show a 7 day pressure graph instead of only today’s number?
A single reading can be misleading on its own. A 7 day graph shows whether pressure is broadly rising, falling, or holding steady, which gives more context for weather awareness and routine planning.
