Sweet spots

Each cell is that destination's own verdict for the month — sweet spot, ok or avoid — with its typical daily high, from the same ten years of climate readings its page is built from. A dot marks a busy month. The last row counts the sweet spots, and the best months are marked.

Between the stops

Hanoi → Da Nang	628 km, about 1h 41m in the air
Da Nang → Ho Chi Minh City	605 km, about 1h 39m in the air
Ho Chi Minh City → Bangkok	716 km, about 1h 47m in the air Nonstop, about 12 a day · 4 airlines By road: 887 km, about 11h 06m

Distances are great-circle and the flight time is estimated from them. A road, train or bus line is listed only where it was measured — flights from AeroDataBox, roads from OpenRouteService, trains and buses from public timetables via Transitous — and none of it is a fare; the searches on each stop's page are where prices live.

Every verdict here is the destination's own: ten years of climate readings, the public holidays that crowd it, and what the flight costs. Nothing is said about Indochina as a whole that was not first measured at each place in it.
