Shoulder (December-March)
Shoulder season varies depending on whether you are in the South, North or the Center.
The whole country is on the move during Lunar New Year festival on this season and prices increase for most of the items in the markets.
The South always has clear skies and sunshine while the north gets hot, but enjoys cooler yet damper winter conditions during this time.
Low Season (April - Jun, Sep - Nov)
This is perhaps the best time to travel the whole country. There are often many promotional programs from travel agencies because they want to attract tourist during this season.
