Vietnam Hanoi Weather in March — Climate Guide
March in Hanoi is moderate
March is moderate for Hanoi.
March is northern Vietnamese spring at its drizzle peak — mưa phùn (persistent light mist) hovers over Hanoi for days at a time. Temperature climbs to 18-23°C / 64-73°F (pleasant) but humidity rises to 85% (sticky). The combination feels like permanent damp.
The Hanoi cherry blossom peak (imported Japanese sakura trees, mid-March) is the photogenic highlight — Long Bien district and several French Quarter parks have small cherry tree clusters that bloom in pink. Less spectacular than Tokyo's hanami but a charming local moment.
