A Simple Guide to Understanding San Francisco Weather
 
Most places have four seasons - spring, summer, fall and winter.  People will tell you that San
Francisco also has four seasons, but this is not entirely true.  Sure, it might be warmer in
October than it is in April, but only by about five degrees.  We're just pussies.  The bottom line
is that San Francisco really only has two seasons - Winter and Not Winter.
 
In Winter, it rains sometimes, and is a bit chilly.  Winter generally occurs some time between
December and February.
 
In Not Winter, it doesn't rain and might or might not be a bit chilly.  Not Winter has been known
to appear briefly during Winter, but it's mostly March through November.
