Tips for Visiting HCMC in September
September has very similar temperatures (between 24°C and 32°C) to that of the months before and after. However, high humidity of 85% (the highest humidity level of the year) and large amount of rainfall with precipitation of 214mm and expected rainy days of 16 (the year’s second highest rainfall amount) make September’s weather more unpleasant than many other months’.
Combination of the moist atmosphere following the downpour and typical tropical heat creates a kind of oppressive atmosphere, which may annoy tourists, especially who come from cool and dry climate regions like Tasmania (Australia), New Zealand, or Canada.
Traveling to the southern metropolis of Vietnam at the beginning of September, tourists can enjoy many cultural- arts programs as well as spectacular firework display which are held to celebrate the National Independence Day September 2nd. Besides, the Mid Autumn Festival which is mostly for children and celebrated on the full moon of the lunar august often takes place on September too. Visiting Ho Chi Minh City on this occasion, tourists will have chance to take part in joyful lantern procession, watch exciting lion dancing, taste the moon cake, and enjoy the fun with the locals.
