Residents of Chennai woke up to a pleasant and partly cloudy morning on Saturday, December 6, 2025, setting a comfortable tone for the weekend.

Today's Weather Breakdown: Warm Breeze and Evening Showers

The maximum temperature is expected to reach 28.2°C, while the minimum will settle around 23.3°C. The current humidity level of 77% adds a muggy feel, but a steady breeze blowing at 23.4 km/h will provide some relief from the discomfort.

Weather models indicate a significant 88% chance of rain throughout the day. These scattered showers are most likely to develop in the late afternoon or evening, particularly after 4 PM. The rainfall is expected to bring cooler temperatures in the evening, creating an ideal setting for outdoor relaxation.

Air Quality Report: A Refreshingly Clean Start to December

Friday, December 5, provided a breath of fresh air for Chennai, quite literally. The city's air quality was recorded in the 'Good' category with an AQI-IN index of just 22, one of the cleanest readings in recent weeks.

The levels of harmful particulate matter were notably low, with PM2.5 at 13 and PM10 at 19. This indicated minimal pollution and offered a perfect window for outdoor activities. While increased moisture from today's anticipated rain may affect these levels, the clean air has set a positive tone for the beginning of the winter month.

Daily Planning and Weekly Outlook

Given the warm and humid conditions, experts recommend wearing lightweight clothing and applying sunscreen when heading out. Carrying an umbrella is advised for the evening due to the high chance of patchy rain.

For fitness enthusiasts, the early morning or post-sunset hours are the best times for outdoor exercise to avoid the day's warmth. Even with the good air quality, wearing a mask in high-traffic zones like T. Nagar or Mount Road remains a sensible precaution against dust and vehicle exhaust.

Looking at the week ahead, Chennai can expect a mix of conditions:

  • Weekend (Dec 7-8): Similar weather with highs near 27°C and a chance of light rain.
  • Early Week: Clearer skies with sunny days and cooler nights, ideal for planning outings.
  • Midweek: A slight rise in temperature coupled with a drop in humidity for a more comfortable feel.
  • Thursday: Projected to be the brightest and warmest day, perfect for a beach visit.

This combination of breezy weather and improved air quality offers a wonderful opportunity for Chennai's residents to enjoy the early hints of the city's winter charm.
