The weather here in Hanoi in November is cool, definitely much cooler than most of Vietnam, especially in the evenings and early mornings. Some clothing hints to be taken into account:
1. Sweaters: Light sweaters and/or cardigans layered over windbreakers or denim jackets are an excellent way to give warmth in the colder evenings that remain still well-styled. White or beige cotton knits could go for almost every occasion.
2. Outerwear: A knee-length leather jacket or a parka is one item that is indeed very important for keeping you warm in the cold during other parts of the year when you visit Hanoi. You may also consider pistachio green fitted with some woolen-style headgear.
3. Tights or leggings: Comfort and versatility in other conditions, like chilly weather, keep your legs free and bulkless. You want to use some moisture-wick, breathable materials, perhaps wool, nylon, or polyester.
4. Boots: If you want to buy boots for hiking on the roughness and exploring ancient sites of Hanoi, make sure they are sturdy leather, suede, or synthetic material especially in this heavier season for your trip.
November in Hanoi bears calm weather with moderate temperatures in the region of about 20-25OC (68-77OF). Here's some advice on what to pack:
1. Long sleeves: Light fabric, for some warmth in the night.
2. Trousers or jeans: Light to medium-weight or long skirt or dress is also fine, if preferred.
3. Light sweater or jacket: To throw on during those cool evenings and mornings.
4. Good walking shoes: Comfortable, for walking around forces you to be completely enchanted by Hanoi.
5. Rain gear: November days are quite dry, but nothing too bad can happen if you ensure you pack a rain jacket or umbrella.
6. One or more pairs of socks and underwear: Some few pairs of socks and underwear according to the duration of the visit.
7. Accessories: Scarfs help create an extra layer of warmth. Hatter and shades to keep away from sun rays.
In general, most of your clothing will be layers, and a layer can be added or removed easily, depending on the weather during the day.
