Is it true that Singapore's temperature is expected to soar to 40°C in the next few days?

17 March 2016

This is not true.

NEA is aware of a message circulating via text messaging and social media platforms which claims that temperatures are expected to soar to 40°C in the coming days, resulting in a possible heatwave leading to dehydration and sun stroke. These claims are untrue.

Rumours on Whatsapp of soaring temperatures

The Meteorological Service Singapore (MSS) issued an advisory on 15 March 2016 stating that the second half of March 2016 is expected to be drier and warmer than that experienced in the first fortnight of the month. During this period, the daily maximum temperatures are expected to range between 33°C and 34°C, and could reach a high of around 36°C on a few days.

The warmer conditions that we are experiencing are due the continuing influence of the El Nino and the presence of a dry and warm air mass over the region. The occurrence of the equinox1 is another contributing factor to the warm temperatures during this time of the year.  Despite the drier conditions, short-duration thundery showers in the afternoon on four to six days can still be expected over parts of Singapore, due to strong solar heating of land areas and convergence of winds in the surrounding vicinity. 

The Ministry of Health (MOH) advises that the precautionary measures individuals can take to minimise the risk of heat-induced illnesses during warm weather are as follows:-
  • Wear loose-fitting, heat permeable and light coloured clothing
  • Drink fluids to stay hydrated 
  • Take more breaks between activities
  • Reduce outdoor activities during the hottest time of the day or stay in the shade 
  • Sponge with cool or ice water 
  • Plan your sport and exercise activity in the cooler hours of the day
  • Watch for early symptoms2 of heat-induced illness and seek medical attention if the condition persists or worsens

For official and authoritative information on weather conditions, the public should refer to NEA. For updates of the daily weather forecast, please visit our MSS website, or download the myENV app.

1 An equinox occurs twice a year around 20 March and 22 September. During an equinox, with the sun directly overhead around noon, sunlight reaching the earth’s surface is most intense and contributes to higher daytime temperatures

2 Symptoms of heat-induced illness includes headache, nausea, dizziness, fainting, rapid heart rate, poor concentration, muscle ache, muscle cramps, blurred vision, loss of co-ordination, disorientation or confusion, seizures or fits, vomiting, and decreased and dark-coloured urine
