How we score weather
How we score months: each starts at 50 and earns or loses points across three signals. Temperature in the 18 to 26°C comfortable band adds 30; 14 to 17°C adds 15; warm 27 to 30°C adds 10. Past 30°C or below 14°C the page starts taking points back, with a 30-point hit at the extremes (below 5°C or above 33°C). Rainfall under 60mm adds 15, 200mm costs 25, over 300mm costs 40. Sunshine over 240 hours adds 10; under 80 hours costs 20. The result lands in one of four bands: Excellent (80+), Good (60-79), OK (40-59), Avoid (under 40). Crowds and prices come from the events calendar, separately, so weather and busyness stay readable as two different signals.

Peak demand in Hoi An starts in January. Lock flights and the room you actually want by September, or you'll pay for what's left.
