What is this?

This is the only web application dedicated to showing barometric pressure histories, forecasts and maps for any location in the world.

Who is this for?

Humans: Barometric pressure fluctuations can lead to migraine headaches, joint pain, arthritis symptoms, and blood pressure changes among other physical changes in the human body. Some people can predict weather patterns due to their bodies’ responses to changes in pressure. It can help to know in advance when the pressure will change in order to make lifestyle or medication adjustments beforehand, which is where this forecast graph can be helpful!

Meteorologists: Barometric pressure, also known as atmospheric pressure, is a leading indicator for inclement weather. Generally, low pressure systems are associated with cooler temperatures, precipitation, wind and storms.

Fishermen: Some fish respond to changes in barometric pressure and can change their level of feeding activity when pressure is dropping. Thus, fishermen might avoid fishing when pressure is dropping and seek out times to fish before or after those periods.

Where does this data come from?

The weather data comes from the Dark Sky weather API. The map view is from Windy.com. If the data in your area are inaccurate or unavailable, that’s probably an issue with a data source, but please let us know by leaving a feedback message (at the bottom of the page) so we can check on it!

Is there a mobile app?

Yes, but probably not the way you think. Barometricpressure.app is built as a Progressive Web App (PWA), meaning that it can be downloaded onto your device directly from your browser and accessed just as you would access any other app on your device. That means that you can install this app to your iPhone, Android device, tablet or even a desktop computer! Check out the following link to learn more:

How can I save my location?

  2. Save the URL of your location's data page to your browser's favorites or bookmarks folder.

The app is not working for me. What should I do?

We apologize for that. We are running this app on a shoestring budget while we’re trying to get it off the ground, so sometimes we hit our allotted data limits with our data providers. Check back again after some time and it should work. Either way, please leave us some feedback so we can help if you are experiencing problems by clicking on the “Feedback” link, below.
