I mark it up to reliance on public transportation - whether it's on foot, by bus or subway nothing like standing around at the office looking like a drenched rat.
Japan was different though. I just flipped on a channel and listened to the weather girl/eye-candy cheerfully explain what miserable weather I could look forward to today. BUT if you don't happen to understand what our fashion statement is chatting on about, there are two sites I've found very reliable over the long run:
Weather Channel: SEOUL
Weather Channel: PUSAN/BUSAN
Weather Network: SEOUL
Weather Network: PUSAN/BUSAN
Oddly enough, as much respect as I have for the BBC, I have found their weather forecasting way off - lacking even the marginal bit of accuracy you can expect from your average forecast. They will show up in your goggle search but make sure you stay clear of them.
Thanks again for stopping into my little corner of the 'net, and Happy Browsing!!
