Singapore in January

It is early in the Northeast Monsoon, and in some years grey, showery spells last for days. This follows the wet December, though the air starts to dry out toward February. In years when Lunar New Year falls in late January, check the holiday dates ahead.

Singapore in January ran hot: 31°C by day and 24°C at night. By midday the shade was the best seat in town. Rain fell on 11 days of the month on average. The average is 11, but individual years ran from 4 (2014) to 21 (2024).

This was the last frequently wet month; rain eased to about 6 days the month after. Highs topped 30°C on 21 days of the month on average. Mixing in indoor stops at midday made sense. Each rainy day brought about 25 mm, closer to downpours than drizzle.
