Today’s Hourly Pressure
Today’s Barometric Pressure Chart
This chart uses hourly forecast sea-level pressure from the current hour through the rest of the local day. Use it to compare the current reading with the shape of today’s expected rise, fall, or steadier period.
Hourly Detail
Today’s Hourly Pressure and Trend
Each row shows forecast sea-level pressure for the remaining local hours. Three-hour change compares that hour with the forecast three hours earlier. Trend uses the app’s 0.5 hPa deadband: up, down, or steady.

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 today’s hourly chart instead of only the current number?
A single reading cannot show direction. Today’s hourly chart adds the expected movement through the rest of the local day. For a longer view, use the 7-day barometric pressure forecast.
