Ambient pressure in widgets?

I'm afraid that doesn't do what you expect. In the Settings/Sensors and accessories/Barometer, if I change the watch mode from auto to Barometer, it still shows the sea level pressure. If I change the Pressure unit, it does change the unit displayed in the widget, but the reading as I say is still sea level not the ambient pressure of my location.

Out of curiosity, why do you want the ambient pressure AT YOUR LOCATION instead of the Sea Level Pressure AT YOUR LOCATION?

All pressure measurements are local - there is no reading "from the nearest sea level location."  The watch simply "translates" ambient pressure to sea level pressure.

HTH

Maybe to avoid the (varying) errors of that "translation"? I would  trust  a graph of the behavior of the ambient pressure more than the graph of a sea-level-reduced pressure, given that to perform this reduction the watch must estimate altitude, most likely temperature profile (or use a mean value for it, which adds further errors), etc.

With the ambient pressure, you still have the sensor error, but not any additional errors. I also think that the storm alert would have been better implemented if it was based on the ambient pressure, before whatever hocus pocus is going on in the reduction-to-sea-level algorithm. For a definitive conclusion one would really need to see the exact algorithm that Garmin uses for this reduction to sea level, of course. We never will, I guess. :)

Best regards

Absolutely. I don't know why I'm seeing just the reference sea-level data which comes from any internet source instead of the real ambient pressure, that like temperature, speed.. is a real and current reading for my situation. 

The storm alert algorithm is indeed useless if you are doing activities with altitude changes. Just a 200m altitude change while cycling triggers a storm alert. The Instinct is calculating and showing to me an altitude change based on ambient pressure change which is a good assumption if I'm performing an activity, but at the same time it also assume that a storm is probably. One thing should exclude the other, at least while an activity is ongoing.

If I could for instance see the ambient pressure I could know by myself a storm is probably if I can see the pressure reading going low too quickly.

I love the Instinct in just a week with it. It is just strange this reading is missing.

As Gaijin said, the sea level pressure is not obtained from the internet. It is obtained from the ambient pressure measured by your own sensor, after some calculations to account for your altitude. It is all done within the watch. On this reduction-to-sea-level algorithm, of course, some additional errors are made, because to do it properly would required additional data that the watch does not possess.

I suppose Instinct takes average air pressure for given altitude (from some internal table or calculation) with measured air pressure and by this ratio multiply average air pressure at 0 m above sea (1000 hPa I think).

If the average air pressure for 220m is 973.7 hPa and  for 0m 1000 hPa, (994.2/973.7)*1000=1021 hPa.

 So when you set the altitude to 0m above sea, you will get (994.1/1000)*1000=994.1 hPa .

This way you can see the ambient pressure in widget or even on the main screen 

But without tenths 

My understanding is that the watch measures ambient pressure. It isn't a 'smart watch' and doesn't have a direct line to any meteorological sites. The pressure reading decreases with height gained and with the movement of weather systems.

Or are you referring to features that my standard Instinct doesn't have?

Where exactly in the menu is this screen that shows "ELEV / AMBIENT / BARO. PRESSURE"?

I have the Instinct Solar for a week and still frustrated by the inadequate pressure indicator...

P.S. I just figured it out! These are from "Other Fields" for a data screen in activity settings. Thank you!

I have a Casio watch with barometer reading which of course shows the real ("ambient") measurement. This is the pressure you actually experience. As a hiker why would you need the calculated SLP at 2500 meter high in the mountain? I guess meteorologists may need the SLP for getting the whole picture of relative pressure in a large area. But for me when hiking I need just the real measurement at the exact location point where I am.
