December 2025 Pakistan Climate Outlook: Smog, Rainfall, and Health Advisory

By /

December is one of the most important winter months in Pakistan, marked by falling temperatures, early-morning fog, increasing smog, and the arrival of western disturbance rain systems. As the year ends, Pakistan experiences a noticeable shift in weather patterns due to cold waves from the north and dry continental winds from the west. December 2025 is expected to follow these typical trends, bringing a mix of cold weather, dense smog in Punjab, light to moderate rainfall, snowfall in northern areas, and colder nights across the country.

Overall Weather Outlook for December 2025

December marks the beginning of the true winter season in Pakistan. The month usually remains dry in many regions, but western disturbances can bring short spells of rain and snowfall. In 2025, meteorological patterns indicate:

  • Persistent smog in Punjab during early weeks
  • Dry conditions in Sindh and Balochistan
  • Moderate chances of rain in northern and upper regions
  • Heavy snowfall in mountain areas during late December
  • Lower visibility due to fog and smog combinations

December is generally known for stable weather, but sudden cold waves may cause a rapid drop in temperature.

Smog Conditions During December 2025

Smog remains the biggest environmental challenge of December in Pakistan, especially in Punjab. The month begins with high pollution levels and low wind conditions, which trap pollutants close to the ground.

Why Smog Intensifies in Early December

  • Low wind speed prevents pollution dispersion
  • Temperature inversion locks pollutants at ground level
  • High humidity mixes fog with smoke
  • Vehicle emissions increase due to winter traffic
  • Crop residue burning from November continues to impact early December

Cities Affected by Smog in December 2025

1. Lahore

One of the most polluted cities during winter.
Visibility may drop to 50–150 meters in early mornings.

2. Faisalabad

Industrial emissions and low winds worsen smog levels.

3. Gujranwala, Sialkot, Sheikhupura

Combination of industrial smoke and fog leads to thick smog layers.

4. Multan and South Punjab

Smog is milder but still affects health and visibility.

Health Impact of Smog

Smog can cause:

  • Coughing and throat irritation
  • Eye redness
  • Difficulty in breathing
