How extreme does Hanoi's weather get?

The hottest, coldest, wettest and snowiest days Hanoi has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 13 years of daily weather observations (2012–present), from the Ha Dong station 10 km away. Updated through August 2025 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

The four kinds of extreme

The hottest, coldest, wettest and snowiest single days Hanoi has recorded — each shown against what a normal day that time of year looks like.

In plain terms

Across the record, Hanoi has reached as high as 108°F and as low as 43°F. A single day has delivered over 13 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.

Methodology & sources

Temperature & precipitation — 1991–2020 normals computed from 30 years of daily observations at Noibai Intl, a weather station, about 22 km from the city centre. The underlying daily records come from NOAA's global station network.
