It will not be a white Christmas in The City, but that probably doesn't come as much of a surprise.
It rarely is.
Instead, Christmas Day in San Francisco will be pleasant and clear, dry and sunny even, according to the National Weather Service.
The day's low is expected to be 46 degrees and the high 65.
Since records have been kept on local temperatures, 1967 has the distinction of the highest Christmas Day temperature with a less than whopping 67 degrees.
More recently, in 1990, the record low was a chilly 35 degrees.
For some historical perspective, back in halcyon 1890 it was 42 degrees.
The rest of the week, according to the weather service, is expected to be much the same as Christmas Day.
And, in case you were wondering about rain, none is on the horizon.
