Why is the temperature outside not the same as it was exactly 365 days ago?

If it takes the earth 365 days to complete one rotation around the sun, why is the temperature outside not the same as it was on June 22, 2022? I understand that clouds and rain change the temperature but that’s not the only reason right?

The weather is based on many factors, including wind patterns, cloud cover, air pressure, solar activity, volcanoes… It would actually be stranger if the temperature was the same on the same day each year considering all the variables.

There’s a whole lot of reasons why temperature varies.

Cloud cover, what air masses are currently in that location, wind speeds, humidity, pollutants like smoke or ash in the air, and even the sun itself, as the sun is not perfectly consistent with how much energy it puts out from day to day.

There are countless other variables—so many that even supercomputers have trouble tracking them.

The simple direction that the wind is coming from that day will cause a big swing: warmer air can be brought in from the south, or cooler from the north (in the Northern Hemisphere). Also, how air mixes from the upper atmosphere will change ground level air temp.

Shifting ocean currents bring water of different temps which will affect the air above, which in turn affect the places the wind blows to.

Whether it’s cloudy or sunny will change temps, as will dust in the air.

I’m not sure I understand why you think it should be. Daily weather doesn’t have to do with where the Earth is in its orbit around the sun. Sure, the seasons heavily influence average temperatures during a given time of year, but daily weather patters are determined by things like wind speed, air pressure, cloud cover, humidity and precipitation, and many more variables than just where the Earth is in its orbit.
