Chiang Mai in January The middle of the cool dry season. There is little rain and the sky is clear, so days are warm and mornings and evenings need a light layer. Towards the end of the dry season, hazy days can start to appear.
Highs averaged 30°C and lows fell only to 16°C, so evenings brought some relief. Nights ran about 14°C colder than the afternoons, so a layer earned its place in the bag. Rain was rare: 1 rain day on average. 8 of 20 years had a completely dry January, while 2017 reached 4 rain days.
19 days past 30°C made it a month for early starts and a long lunch indoors. Not every year was typical: 2020 ran 2.1°C warmer than the mean, with highs of 32.1°C.
