Delhi Records Highest January Rainfall in 3 Years, Temperature Anomalies Observed
Delhi's January Rainfall Hits 3-Year High, Temperature Swing

Delhi Witnesses Unusual January Weather Pattern with Substantial Rainfall

New Delhi experienced light to moderate showers throughout Friday, accompanied by overcast skies and gusty winds that created hazy daytime conditions. The cloud cover played a significant role in maintaining elevated minimum temperatures while keeping the outdoor environment relatively cool. Meteorological experts attribute this unusual weather pattern to snowfall effects in northern mountain regions influencing Delhi's atmospheric conditions.

Record Rainfall Measurements and Temperature Anomalies

The capital city recorded 13.2 millimeters of rainfall between 8:30 AM and 5:30 PM, marking the highest single-day precipitation in January over the past three years. This measurement surpasses recent records, with the last higher reading occurring on January 30, 2023, when Delhi received 20.3 mm of rain.

The persistent rain and cloudy conditions dramatically reduced the temperature differential between daytime maximum and nighttime minimum readings to just 2 degrees Celsius. The minimum temperature settled at 13.7°C, representing a substantial 6-degree increase above seasonal norms and the highest January minimum recorded in four years. Comparatively, Delhi last experienced similar minimum temperatures on January 9, 2022, at 13.8°C.

Meanwhile, the maximum temperature reached only 16°C, registering 4 degrees below the expected average for this period. This unusual compression of the temperature range created distinctive weather conditions rarely observed during Delhi's winter months.

Regional Rainfall Distribution and Air Quality Impact

Rainfall measurements varied across different monitoring stations in the National Capital Region:

  • Safdarjung: 13.2 mm
  • Palam: 14 mm
  • Lodhi Road: 13.4 mm
  • Ridge: 17.4 mm
  • Ayanagar: 11.5 mm
  • Mayur Vihar: 7.5 mm

The precipitation positively influenced air quality indicators, with the 24-hour average Air Quality Index improving to 282 in the poor category from Thursday's reading of 322 in the very poor zone. This demonstrates how weather events can temporarily mitigate pollution levels in urban environments.

Meteorological Analysis and Expert Insights

Mahesh Palawat, Vice-President at Skymet Weather Services, explained the temperature dynamics: "The elevated minimum temperatures resulted from cloudy nighttime conditions that prevented heat escape. Similarly, cloud cover, wind patterns, and adequate rainfall prevented daytime temperature increases, creating this unusual thermal equilibrium."

The India Meteorological Department has not issued color-coded weather alerts for Delhi over the next six days but forecasts changing conditions. A temperature decrease is expected from Saturday through Monday as cold north-westerly winds return to the region.

Upcoming Weather Patterns and Forecast Projections

Meteorological models indicate another western disturbance developing from January 26 onward, which will temporarily interrupt the north-westerly wind flow. Palawat elaborated: "North-westerly winds will persist for approximately two days before the next weather system arrives. While minimum temperatures will decrease, the dip won't be severe enough to create coldwave conditions."

Further temperature reductions are anticipated only after January 29, following the passage of the upcoming weather system expected between January 27-29.

Short-term forecasts predict:

  1. Shallow to moderate fog conditions in coming days
  2. Cold north-westerly winds reaching speeds up to 20 km/hour
  3. Minimum temperatures ranging between 6-8°C until January 26
  4. Maximum temperatures gradually increasing: 16-18°C (Jan 24), 17-19°C (Jan 25), 18-20°C (Jan 26)

This unusual January weather event highlights how changing atmospheric patterns can create unexpected meteorological conditions in northern India, affecting temperature norms, precipitation records, and urban environmental indicators simultaneously.
