it has to do with the ocean, which is a huge temperature balancer, since the ocean temps vary only by about 10-15 degrees year round, and never gets above the mid-high 80's in temp, so it soaks up all the heat in the air in the summer, and radiates its warmth into the air in the winter. There is no such thing as cold. Cold is only the absence of heat, or so my high school teacher taught us, and the ocean stores a LOT of it.
