|Hanoi temperature in the end of summer|
In Hanoi, the weather and temperature, the amount of rain and climate are unlike any other areas in Vietnam. Although Hanoi is the centre of the north of Vietnam, but Hanoi temperature is obviously different to sub-areas such as Sapa in Lao Cai, Dong Van and Meo Vac in Ha Giang, Cao Bang and Ha Long Bay, Hai Phong, Trang An in Ninh Binh, ect...
However, Hanoi climate is typical for the Red River Delta.
In Hanoi, the prominent feature about climate and temperature is tropical monsoon climate (in summer, the weather is hot and sunny. There are lots of rains. In winter, the weather is cold, it is hardly rain and the humidity rapidly decrease)
In summer, the radiation of the sun in Hanoi is so strong that the temperature rise swiftly.

However, in Vietnam, specially in Hanoi, the amount of rains is rather high comparing to the countries in Northern Europe, Russia, Mongolia, Korea, Japan and so on. That is why in Hanoi, the air humidity is never lower than 70 percents, the average rainfall is about 1.500-1.700 milimeters and if there are 365 days per year, the number of day which has rain in Hanoi is about 145 days.

However, because of the strong effect of monsoon, the beginning and ending time of seasons does not remain the same each year, so the division of months is only relative. That is why in Hanoi, some years, winter comes early than other years.

Morever, due to the influence of urban and greenhouse effects, on summer heat waves,you might feel that the actual temperature is always higher than the one which you could measure, it might reach to 50 degree Celsius.
