The climate in Singapore

Located only about 140 north of the equator, Singapore offers a typical tropical rainforest climate characterized by high humidity and consistent temperatures. With only minimal temperature fluctuations, the average year-round maximum temperatures range between 30 and 33 degrees Celsius and average minimum temperatures between 24 and 26 degrees Celsius. The only seasonal variation here is in terms of precipitation.

There are two distinct monsoon seasons in the city-state. The northeast monsoon, which lasts from December to March, brings slightly cooler temperatures and occasional precipitation. The southwest monsoon, from June to September, is generally hotter and wetter, and thunderstorms are more frequent.

Singapore is known for its abundant rainfall. The city receives an average of 2,400 millimeters of rain per year. Showers occur throughout the year, but the wettest months are from November to January.

Long-term development of temperatures from 1993 - 2022

In contrast to single record values, long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. An average value would give a distorted result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and distorts the average again. The subsequent long-term development was therefore reduced to only 1 measuring points in order to have comparable data over as long a period as possible.

In the years 1993 to 2022, there were only these 1 weather stations in the whole country, which reported continuous temperature values (Changi). From these weather reports, we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was March 1998 at 29.5 °C. January 2021 was the coldest month with an average temperature of 25.8 °C.

The average annual temperature was about 27.7 °C in the years after 1993 and about 28.0 °C in the last years before 2022. So over the past 30 years, it has only increased by a minimal 0.3 °C. This trend only applies to the selected 1 weather stations in Singapore. A considerably more comprehensive evaluation of global warming has been provided separately.
