The coldest day in Bangkok is on its way - and with it deteriorating air quality

2025-01-08

Bangkok and large parts of Thailand are currently experiencing an unusually cold spell, and according to weather experts, January 13 could be the coldest day so far this year. Forecasts show temperatures could drop to as low as 15°C in Bangkok, while northern parts of the country could experience single-digit temperatures. The cold spell is expected to last until January 20.

The cold persists – and the smog worsens

However, with the cold comes another challenge: deteriorating air quality. In recent days, residents of Bangkok have reported an increase in smog and air pollution. This is because the cold air causes the particles to stay longer in the atmosphere, leading to higher concentrations of PM2.5 and other harmful substances.

Health risks and recommendations

Health authorities have issued warnings urging residents to wear face masks outdoors and avoid prolonged stays in areas with high air pollution. Particularly vulnerable are children, the elderly and people with respiratory problems. Those who are able are advised to use indoor air purifiers and stay updated on the air quality index through official sources.

Measures to mitigate the effects

The Bangkok Metropolitan Administration (BMA) works to reduce air pollution through various measures, such as limiting emissions from vehicles and industry and encouraging the use of public transport. However, experts point out that long-term solutions are required, such as more green areas and better air ventilation in the city.

Air pollution and how you can follow the development

Air pollution is measured by the air quality index (AQI), where high levels of PM2.5 and PM10 can cause health problems. Common AQI levels:

  • 0-50: Good air quality
  • 51-100: Moderate air quality
  • 101-150: Unhealthy for sensitive groups
  • 151-200: Unhealthy for everyone
  • 201-300: Very unhealthy
  • 300+: Hazardous air quality

To follow the air quality in real time, apps such as AirVisual and AQICN be used. They provide updates and forecasts for air pollution in various areas.

What can we expect?

Weather forecasts indicate that temperatures will gradually increase after January 20, but air quality may remain poor depending on weather conditions and emission levels. Authorities are urging residents to be cautious and take steps to protect their health during this period.

The coming week will be a challenge for Bangkokians - both because of the cold and the increasing air pollution. Thailand Info continue to monitor developments and report on any new measures to improve the situation.
