What to pack for Hanoi in January

UV index of 5.1 burns skin fast despite the short 11-hour daylight.

Glare off wet surfaces during 10 rain days makes eyes strain without polarization.

Jungle terrain near the national park hosts mosquitoes year-round, tap water unsafe too.

Insect bites, waterborne illness, and minor cuts all happen in the same trip.

Tap water isn't safe here. A filter bottle beats buying plastic twice a day.

Eleven hours of daylight means your phone dies before sunset on busy days.

Set it up before you land. Signal drops for long stretches outside cities.

Dark by 5:35pm. Every campsite chore after that is a two-hands job.

Overhead bins on regional flights to the national park fit nothing larger.

Day hikes near the park need a bag that doesn't soak through in 10 rain days.

Fits the overhead on every airline that matters. Skip the checked-bag line entirely.

For the passport, the chargers, and the one dry pair of socks.

Humidity at 76% means sweat clings all day, even in the mild 14 to 70°F range.

For temples, mosques, and churches that check at the door.

Treat the clothes once and it lasts weeks.

Diarrhea from tap water leaves you dehydrated in the humid 76% air.

Tap water causes stomach trouble that lasts days without the right tablets.

One brick charges the laptop, phone, and camera.

Hotel and cafe wifi is shared with everyone else in the building. A VPN keeps your banking and email to yourself.

International airport and urban crowds make pickpockets common in Hanoi.

Baggage handlers at the airport don't always treat luggage gently.

Moisture at 76% ruins unpacked clothes faster than organized cubes prevent.

Ten rain days mean laundry dries slowly, so detergent lets you rewear items.

Scooter traffic noise at 14 km/h wind speed makes sleep impossible without masking sound.

The sun climbs high enough in January to bleach your vision without a brim.

Mosquitoes hunt at dusk when daylight ends by 5 PM in January.

Tap water isn't safe, so hands need sanitizer before eating street food.

Sunburn and insect bites both sting, but regular relief creams burn skin further.

One outlet per guesthouse charges nothing without short cables for multiple devices.

A few phrases go a long way. Ten minutes a day before you leave is plenty.

An international destination requires a passport holder to keep documents dry in humidity.

Hostels and budget guesthouses see luggage theft, so locks matter.

Humidity fogs lenses and rots gear in a shared bathroom.

Overnight buses to the national park have thin pillows that offer no neck support.
