Singapore in August

August 9 is Singapore's National Day. Haze can begin to arrive from late in the month in some years. The seventh lunar month, known as Ghost Month, starts in August or September. Rain is middling for the year.

Days averaged 31°C and nights 25°C. Midday was for air conditioning, a cold drink or a long lunch out of the sun. There were 12 rain days on average, roughly one day in three. It varied a lot from year to year. August 2018 had 3 rain days; 2021 had 22.

Highs topped 30°C on 28 days of the month on average. Mixing in indoor stops at midday made sense. Rain days averaged 15 mm each, so when it rained it rained properly.
