What does H/L stand in the default watch face?

Hello. It stands for the highest and lowest air temperature of the current day.

As I said, silly question

thanks a lot for your reply

No problem.

Thanks a lot! I have been looking for this answer for 1 month (since I got my fenix 6)... could not find it as I was looking for it in french H/B

It will only show  numbers if connected to a mobile, which i understand. What i don´t understand is, that if you switch the data  field to current temperatur, that it will behave the same and relies on a connection to the mobile. Why is it not able (or choosable for you) to use the temperature sensor of the watch and show this value?

The temp sensor in the watch isn’t meant to show the current ambient temp. It’s there as part of the barometer and therefore it’s supplying the temp inside the watch, which is affected by your body heat, because the barometer needs to know the temp at the pressure sensor.

Garmin confuses a lot of users by adding the data from that thermometer to activity files.

The temp sensor in the watch is useful when you have the watch on a bike mount when cycling, so it is OK to have this sensor data added to the activity files

Thanks also...... just wish I could change some of these settings to mileage done this week or daily steps etc etc
