What December actually feels like
December is Hanoi's cool season in lived terms: mild, holiday atmosphere. Most days feel cold, dry and often clear, with damper grey stretches arriving in bursts rather than settling in for the whole month Check the full climate tables below for monthly averages and packing cues.
The underestimated variable is short daylight. It truncates outdoor evenings and pushes dinner earlier. Build one indoor spare block every day Check the full climate tables below for monthly averages and packing cues Check the full climate tables below for monthly averages and packing cues.
Early December often starts near 22°C while the final week trends toward 22°C. That 1° drift is enough to change coat weight mid-trip. Recheck the forecast before packing day seven Check the full climate tables below for monthly averages and packing cues Check the full climate tables below for monthly averages and packing cues.
Afternoons reach 22–23°C before an early sunset near the 9.3-hour daylight limit — plan open-air stops then.
Evenings cool quickly toward 15°C; shift to indoor dining and illuminated streets once the light drops.
