Rising Heat and Extreme Weather Projected in Singapore

February 2024

The Centre for Climate Research Singapore, part of the Meteorological Service Singapore (MSS), recently released the Third National Climate Change Study (V3) findings. The study projects higher temperatures, more wet and dry extremes, and accelerating increase in mean sea levels for Singapore and Southeast Asia by the end of the century, consistent with the Intergovernmental Panel on Climate Change 6th Assessment Report.

Singapore’s temperatures are set to rise significantly, with annual mean temperatures projected to increase by 0.6 to 5 degrees Celsius by the end of the century. Very hot days will become more common, with 41-351 days exceeding 35 degrees Celsius annually by the end of the century.

Rainfall patterns will become more intense, with longer and more intense dry spells from June to August, and heavier rainfall from November through to January. Mean sea levels around Singapore are expected to rise by 0.23m to 1.15m by end century, and up to 2m by 2050 under a high emissions scenario.

Under the Singapore Green Plan, the country is committed to reach net-zero carbon by 2050, and will engage in adaptation planning to prepare for the impacts of climate change. MSS will also endeavor to share data with ASEAN member states and collaborate with international entities and the scientific community.

The National Environmental Agency also launched a second grant under the Climate Impacts Science Research (CISR) Programme for new research proposals on food security, impacts on human health, water resources, sea level rise and impacts on maritime infrastructure and the transport sector. These projects will make use of V3 findings to investigate the impacts of climate change in Singapore.
