SINGAPORE: Last year was Singapore’s warmest on record, tied with 2019 and 2016, the Meteorological Service Singapore said on Friday (Jan 10). 

All months recorded temperatures that were equal to or above their respective long-term averages, according to the Met Service’s Singapore Climate 2024: The Year in Numbers report. 

The 2023/2024 El Nino event contributed to Singapore’s warmer temperatures in 2024, as well as rainfall earlier in the year.

April was the warmest month last year and also the warmest April on record. 

The month’s mean temperature of 29.4 degrees Celsius was 1.2 degrees Celsius above the long-term average and tied with 2016 as the warmest April on record, said the report.

April 2024’s mean daily minimum temperature of 26.7 degrees Celsius also tied with 2016 for the highest April mean daily minimum temperature.

July was the second warmest month in 2024. 

It was also the warmest July on record - its mean temperature of 29.3 degrees Celsius was 1.1 degrees Celsius above the long-term average for the month and surpassed the previous warmest July recorded in 2015 by 0.2 degrees Celsius.

The month’s mean daily minimum temperature of 27.1 degrees Celsius also broke the previous July record of 26.9 degrees Celsius set in 2019, said the Met Service. 

Last year also saw the warmest December on record.

“While December 2024 was one of the cooler months of the year, it was the warmest December on record with monthly mean temperature of 27.7 degrees Celsius, tying with 2015 and 2021,” according to the report. 

The mean daily maximum temperature of 31.7 degrees Celsius in December broke the previous record of 31.6 degrees Celsius recorded in 2016 and 2018. 

Changi climate station’s highest daily maximum temperature for the month of December was broken by a wide margin on Dec 7, 2024, when the station recorded a temperature of 35.6 degrees Celsius. This exceeded the previous record of 33.9 degrees Celsius set on Dec 1, 2021, by 1.7 degrees Celsius.
