Barometric Pressure Today & Forecast

Live barometric pressure with a 7-day graph, predicted rapid changes, daily forecast, and pressure-change alerts.

Barometric pressure right from your browser CURRENT PRESSURE AT A GLANCE An app-style barometer dial shows the live sea-level pressure for your location, with a rising / falling / steady tendency and a careful low, near-average, or high interpretation. Switch between hPa, inHg, and mmHg. 7-DAY PRESSURE GRAPH Daily average sea-level pressure over the coming week, so you can see fronts and pressure swings building before they arrive. PREDICTED RAPID CHANGES The same algorithm as our mobile apps: pressure rises or drops of at least 4 hPa within 10 hours during the next seven days, one per day, each labeled with the day, the hour it completes, and its direction. Popular with people tracking migraines, headaches, joint pain, and other pressure-sensitive conditions. DAILY FORECAST Seven days of daily minimum, maximum, and trend — derived from hourly data with the app's opening-vs-closing average rule. OPTIONAL DESKTOP ALERTS Opt in and get notified when a rapid pressure change is predicted: falling, rising, or a storm watch for drops of 6 hPa or more. The toolbar badge shows the current pressure in your selected unit.
