PACKING

You should all try to pack mostly loose fitting clothes, as it is really hot and sticky over there.
Duvets and comforters will be nice during the winter, but during the summer they're more of a suicide mission.
DisneyGibbs is right though. For you of you who are leaving in February, you're lucky. That's the coldest time of year, and it can drop down to freezing. No worries though, you get huge coats to wear on the job. I remember getting up at 6 or so to go to work, and there was frost all over.
But then again, it makes it easier to cope with summer as you are, like DisneyGibbs said, gradually thrown into the scortching heats of May through September.
But then when winter comes again, it will feal really cold, as you stumble out of the summer. So warmer clothes would be nice. Pack a sweather, or just buy one over there, they're really cheap.
