[QUOTE=Vitrea]Talking about packing, do locals walk around in shorts and T shirts during the day? It is not always about the weather right. When I go to Asia, I notice that it might be hot as hell but it is rare to see an adult walking around in shorts.[/QUOTE]Do not walk around MDE in shorts if you are more than 12 years old. In Poblado you might get away with it, but other than at the Pool it is not appropriate. Jeans, T shirt and athletic shoes seem to be the standard daytime dress in MDE, it is less dressy than some other Latin countries I have been to and perhaps more Americanized, but still no shorts.
In my experience a small travel umbrella or a light rain jacket is sufficient. Occasionally it will really pour, but then you go inside a cafe or bar or something. It won't last that long.
