When we left Boston on Tuesday it was 0 degrees...a few hours later it was 80 degrees in Naples, Florida. We got a walk on the beach before the rains came and the temps plummeted all the way down to 67!
I know what you mean. I went from a relatively mild winter in the UK to 21ºC in HK for one week and then back to 5ºC in the UK and -13ºC in Berlin and immediately went down with a dreadful cold. Just about got over it now.
