Cold temperatures reduce the pressure, and since air leaks out of tires naturally over time, it is quite common for the change in temperature to suddenly put your tires below the threshold for normal tire pressure.
The cold weather compresses air which reduces the pressure… there no need for a leak for this to take place.
As soon as the day warms or the tires warm (with use) the pressure returns… it’s a pain the ass and I have yet to find a proper source that explains what the proper thing to do is.
I just top up my tires in a cold morning, and now they run 4 psi over the mark when they warm up.
Yes, if the tires were close to the cut off before the temp dropped. The sensor in my vehicle readstire pressure about 10% low in colder weather, which can be enough to trigger the warning on chilly mornings if I haven’t topped it off during the summer.
It’s only normal if you’ve been neglecting to check your tire pressure on a regular basis. Unless you live in a place with a massive yearly temperature differential, properly inflated tires won’t lose enough pressure to trigger the TPMS light once temps drop in the autumn.
Prevent a blowout: please stay on top of your tire pressure, people. Check it at least once a month.
I think you need to check your definition of “massive”. Coming from the opposite perspective, I assumed that essentially everyone sees this when the season turns.
Question for the Lemmings down under: is fall/autumn when it gets cold or when the calendar says October? What season do you call it when the weather turns cold? Or does it just not?
Is it normal for tire emergency lights to come on in autumn?
Just the low tire pressure warning.

We usually get a big enough quick drop in temperatures that I get this each autumn. Even with new tires

Heat up gas => pressure go up
Cool down gas => pressure go down

But tpms means the car tells me when the tyre pressure gets low?

It’s only normal if you’ve been living in an area when temperature drops significantly.
