Understanding Vietnam’s Northeast Monsoon Season
Vietnam’s northeast monsoon, often called the winter monsoon, brings cooler air and higher rainfall to northern cities like Hanoi and Ha Long Bay. The season typically lasts from October to March, with peaks in November and December. Temperatures hover between 15°C and 22°C, and while the weather can be unpredictable, it gives the city a cozy charm.
During this season, travel to Hanoi requires flexibility — sudden showers can delay buses, tours, or flights. Staying connected with a mobile data plan helps you receive real-time updates, rebook tickets, and find dry cafés to wait out the rain. That’s why having the best eSIM for Vietnam is a game-changer for travelers who want reliability and peace of mind.

The first question many travelers ask is what is an eSIM and how does it help. An eSIM card is a digital SIM that lets you access local mobile networks without needing to buy or swap a physical SIM. You simply install a QR code, activate your plan, and enjoy instant mobile data anywhere.
Here’s why an eSIM is especially useful when traveling through Vietnam’s monsoon months:
- Instant connectivity upon arrival — no searching for local SIM shops in the rain.
