This (and every other Dark Sky replacement I've tried) is missing one feature that is crucial to me: hour-by-hour barometric pressure forecast.

I get frequent migraines and big changes in the weather trigger them. The easiest way to predict big changes is by watching for swings in the barometer. There's nothing out there that gives the hour-by-hour barometric pressure prediction (at least on iOS) and it's so significant that it has impacted my overall quality of life.

I’m in the same boat with weather pains, so I decided to make a site with an hourly barometric pressure forecast and history.

https://barometricpressure.today/

It’s currently tracking a lot of cities, so please check if you’re close to any, otherwise, I will soon add a search for specific locations.

I’m open to any feedback.

For a web alternative, on https://merrysky.net/ you can expand "More charts" on the graph to see barometric pressure.

FYI, the iOS Weather app does have this now. If you click on a day in the 10-day forecast, you get a detail view with hour-by-hour forecast data for many metrics. One of them is pressure (although I don't normally look at barometric pressure so maybe this different than what you need).

Edit: You can also click on the "pressure" widget and it brings up the same hour-by-hour detail view.

Thanks for the heads-up! It's not quite as nice as it was in Dark Sky, but I will give this a try.

"Chance of precipitation" isn't one of them though, they'll only give you a predicted inches of rainfall. Should I assume that if there's a nonzero amount of rain in the graph it's a definitely going to happen and I should carry around my umbrella?

Darksky used to make that really easy to check for the entire day and I'm not loving Weather as a replacement.

I have this exact same bone to pick with the Weather app

Glad I'm not the only one, I was starting to wonder if I was crazy because that felt like the main piece of data in Dark Sky to me. But I saw a lot of iOS news coverage saying basically "Dark Sky is shutting down, but don't worry about it because Weather app has its local forecast features now!"

Meanwhile Weather app completely missed the point and gives me a bunch of stuff I don't care about.

You can tell me that the wind at 4 PM is going to be 5 MPH west northwest but you can't tell me there's a 30% chance of rain? Gee that's great, thanks for shutting down Dark Sky!

yup, all I want is the precipitation map so I know if I can go run. I have everything but that now in Weather app.

I've been enjoying https://www.meteoblue.com/ and if you scroll down you'll get a precipition map there.

I could be wrong, but I am pretty sure that Windy (windy.com) offers that: https://apps.apple.com/us/app/windy-com-weather-radar/id1161...

Windy.com shows pressure on their meteogram and is an option for their map display.

What kind of changes are you looking for? and how would knowing the forecast help you prepare or avoid headaches?

Anecdotally my headaches correlate with weather changes but was never able to pinpoint exactly the markers.

yeah I've wondered too. Although I think for me I just feel better when it's colder

I did debate writing how 'headache'y I felt periodically with timestamps (e.g. make a telegram bot -> google sheet) and then add in some weather data and see if it was actually correlated if I plotted them

I’m in the same boat and contemporary headache research doesn’t have any clues yet (aside from the fact that it’s a real phenomenon and we’re not crazy) although it is an area of active research.

I can usually tell by intuition if weather is going to trigger things — I’ll even say, “it feels migrainey out” — but I don’t have one specific weather pattern that is clearly the cause.

That’s why I pay attention to the barometer. The barometer frequently predicts big, nonspecific weather changes so whenever I see one on the horizon I know that I might get a migraine when that happens.

Regarding preparation, I try to get stuff down so I can take it easy around the time when the pressure is shifting.

For example, later this afternoon the pressure is supposed to climb quite a bit so I’m getting critical blockers for work done this morning and then I’m going to visit the gym at lunch. It really helps my stress level if I can finish my plan for the day before a headache puts me out. I hope that makes some sense?

I think Carrot weather also has that feature

CARROT (iOS) has it.
