I'm from Hochiminh city, which is in the southern part of Vietnam and have every feature of a tropical area: various fruits, heat, showers and friendliness
Apart from traditional Lunar New Year, we have Mid-Autumn Festival when people eat special cake and children carry lanterns at night
Also, another interesting thing in our city is that we have a "flower street" every year when the city council invites architecture companies and architecture university to decorate a main street in the centre of the city with a specific mascot (this year it will be "cat") together with many kinds of flowers, trees and decorations.
(well, this picture below is from the 2009 flower street: the mascot was "buffalo")
