Answer 1

seriously!  why is it so cold?  I'm wearing a sweater today!

i'm in south OC.

Answer 2

A cold front apparently moved into the area and brought a cooler, drier air into the San Diego area.

Answer 3

a lot of things can be causing this. What is probably causing your weather is cold front and high pressure. The winds rotate clockwise around a high pressure. If the high pressure is west of you, then you are getting the north winds from it, causing cold.  Once the high pressure moves east, then you will start getting winds from the south, causing warmth. Also cold fronts cause the temps to drop, and warm fronts cause temps to warm up. And also the water temp where you live is cool. So when the winds are coming from the west, then you will cool off, when the winds are coming from the east, then you will warm up

Answer 4

Well you see there's a cold front moving in from the north west and barometric pressure is steadily falling as the high pressure pushes off to our east....LOL I DONT KNOW ITS WEATHER< IT CHANGES.
