Singapore is one giant sauna anytime of the year. November to January are the wettest months but the other months are not exactly dry. The only real deterrent is the lack of refreshing winds during March and September. Generally expect average temperatures to reach around 31°C (88°F) during the day and linger around 24°C (75°F) at night.
