Vietnam Hanoi Weather in June — Climate Guide
June in Hanoi is moderate
June is moderate for Hanoi.
June is Hanoi's hottest brutal month — 26-33°C / 79-91°F with 83% humidity creates felt temperatures of 37-40°C. The midday heat is genuinely dangerous for sustained outdoor activity. Afternoon thunderstorms (240mm rainfall, 14 rainy days) bring some relief but also flooding in Old Quarter alleys.
The Hanoi pattern: clear humid mornings (7-12:00, brutal), heavy afternoon thunderstorms (14-17:00, often 3-5 day rain stretches), recovery evenings (17:30-22:00, somewhat cooler). Air-conditioned cafes + malls become daytime refuges. Bia Hoi Junction at 18:00 cooling.
