It’s completely normal.

The needle is not like American cars which basically don’t move unless you are overheating. You are totally within the operating spec of the car, despite extreme ambient temperatures.

If you simply can’t let it go, change your coolant mixture so that it’s mostly water, and remove your thermostat.
