Which City Has The Most Unpredictable Weather?
Not Milpitas! San Francisco’s weather patterns are unusual as compared to the rest of the country (September has historically been San Francisco’s warmest month, for instance). But they’re predictably unusual, at least on a day-to-day (if not necessarily hour-to-hour) basis. And San Francisco, like the rest of the West Coast, rarely gets severe weather. In other words, it is fairly easy for the weather forecast you see on TV to be correct.
