And averaging.....When it's 80 here, 10 miles west of us....it can be 75.
There are so many factors associated with temperature because temperature is always on the move.
Here in eastern Canada, today it will be 30c (86F) inland but 25c (77F) on the coast. Numbers are for manipulating.
It is about 105 degrees now near Chatsworth, CA (40 miles from LA).
However about 30 miles morth past the mountains you get to Ventura where the temps are predicted to be 86 degrees but accuweather..... says currently 74
So accurate they are.
I say blast those mountains and let the cool ocean breeze thru!
