California - Flights flying over residential San Francisco

This is my curiosity for today -

All day, I have noticed many, many planes flying overhead. Eg., 747,767,Airbus, et al.

I live in the Castro district of San Francisco and have never seen this much air traffic on a continuous basis.

Does anyone know what this is?

Happy holidays...

The wind is blowing the wrong way. When I see planes in my part of the east bay approaching in a rare manner, I'm either glad I'm not flying that day, or dreading the delays I'll find when I get to SFO.
