What is Google temp readings based on?

For example,

Google was saying just -3°C for the place

I measured -15°C with a liquid thermometer myself

Official weather station was saying -16°C

Google goes very off

It is not even based on an unofficial measurements.

It looks like it is just guessing for some places.

I asked Google search:

What is Google temp readings based on?

and it replied with...

In most countries, Google's weather app and browser pulls in forecast information from sources including The Weather Channel and its proprietary machine learning techniques.

But those are not even based on measurement from the surface.

It looks like it is guessing.

@Vivaldi Local weather conditions can vary widely over a small area. Buildings, mountains, and rivers can create different weather patterns. Heat generated by buildings can raise the nearby temperature significantly, compared to just a short distance away.

There is one other thing that can influence the temperature that Google gives, and that is where your device (PC or phone) is perceived to be. That is usually based on the location of the Internet server that you are connected to, which could be several km away from where you are.

I was recently on a cruise in the Mediterranean Ocean, yet my phone thought I was in Dubai... because of the ay Starlink works. That's an extreme case but even local ISPs can be in a perceived location far away from you.

It is a small town so nobody is putting weather weather stations there except the official met service of the country.

So Google was just guessing.

Not based on a measurement from the surface.

My liquid thermometer showed a little warmer than the official weather station readings but it was nothing like Google said.

When official weather station was saying minus -32°C

I measured minus 30°C with the liquid thermometer myself.

Google was saying -16°C then.

On foriegn weather forum

I had problem with some foreign people. They were looking at Google for the place and decide according to what Google says.

They've never even been to the place.

I put the link of the official met service of the country to them. They pay no attention.
