Hanoi in October Hanoi autumn begins. Rain drops noticeably and midday heat settles, so it is named with November as the best time for walking. Typhoon season is not over, and a late storm comes in some years.
October brought serious heat to Hanoi, 30°C on a typical afternoon and 23°C overnight. Early mornings were the best time to be outside. There were 12 rain days on average, roughly one day in three. Averages hide a lot here: one year saw 5, another 18.
Highs topped 30°C on 16 days of the month on average. Mixing in indoor stops at midday made sense.
Typhoons i 6 of the last 20 years had a tropical storm pass within 300 km this month.
