The weather in New York appears to be remarkably predictable. When the man in the radio tells me that it will rain in the early afternoon, lo and behold the skies open up at 2:30pm. When he says that the temperature will reach 73 Fahrenheit, it rises to within a degree or two.
This is in stark contrast to my experiences of London's weathermen who seem to wave their hands about a bit and say that it might rain a bit sometime later in the week (maybe), and the temperature could be "seasonal". Perhaps.
Apparently it's to do with the fact that New York's weather is mainly driven by the American land mass, whereas the UK's is at the mercy of the vagary of the surrounding waters.
I now have a Pavlovian reaction to the word "rain" in the weather forecast and pack an umbrella: I know I'm going to need it.
