Introduction
Delhi's weather is more than just a backdrop for daily life—it shapes commute patterns, influences health, and determines how residents and visitors plan each moment. As the capital transitions from monsoon to autumn, understanding today's temperature, rainfall, air quality, and broader trends is vital for making informed choices.
Current Weather Snapshot: Temperature, Conditions, and Humidity
Today in Delhi, temperatures hover between a minimum of 29°C and a maximum of 35°C. Although the mercury peaks at 35°C, the combination of high humidity makes it feel closer to 37°C. Light rain showers and overcast conditions dominate the day, providing relief from the summer’s lingering heat but contributing to muggy air.timesofindia.indiatimes+1

Morning: The day began with relative humidity around 74%, increasing as rain swept across neighborhoods like Talkatora Road and Feroz Shah Road.
-
Afternoon: Cloudy skies persisted, bringing drizzles and a gentle westerly wind at about 5 km/h.
-
Evening: Intermittent light rain and thick humidity continue, with temperatures gradually cooling after sunset.
Delhi’s humidity today stands at a high 90%, typical for this tail-end of the monsoon, while the UV Index during peak hours hovers around a moderate 3, indicating a need for basic sun protection during outdoor activity.ndtv+2
Rain, Thunderstorms, and Seasonal Transition
The Indian Meteorological Department issued an “orange alert” due to moderate rainfall and the risk of thunderstorms today—a common event in late September. Intense yet short-lived showers offer much-needed respite from heat but also cause localized waterlogging.mausam.imd+1
Rain has been most consistent in southern and central areas, though all zones expect at least a drizzle or light rain at intervals. Thunderstorms bring gusty winds at up to 40–50 km/h, so travelers and commuters should plan accordingly.

September’s Legacy: Historically, September delivers 4–8 rainy days in Delhi, but today’s scattered downpours are above average for this time of the month, signaling a robust monsoon withdrawal.weather2travel+1
The Air Quality Index: How Safe Is Delhi’s Air Today?
Today’s AQI (Air Quality Index) in Delhi is classified as “Moderate”, with a CPCB AQI score hovering around 120–128 at mid-day. PM2.5 levels stand at 37–51 µg/m³, while PM10 ranges from 78–104 µg/m³.ews.tropmet+2
-
Health Advisory: Though this AQI is improved compared to the winter smog crisis, prolonged outdoor activity can still irritate sensitive groups (children, the elderly, and those with respiratory issues).
-
Winds and Rains: Today’s gentle, consistent winds and rain contribute positively by dispersing particulate pollution, helping to keep AQI from rising into the “unhealthy” category—at least temporarily.aqi+1

Expert Perspective: Why Is September Weather Shifting?
Yearly climate trends for Delhi show the monsoon is lasting longer, with September witnessing more rainy days, erratic showers, and an uptick in humidity. Urbanization amplifies the “urban heat island” effect, which raises overnight minimums and slows the cooling after sunset.mausam.imd+1
“This year’s late September thunderstorms perfectly illustrate how Delhi’s climate is becoming less predictable, requiring smarter adaptation in infrastructure and personal planning,” notes local meteorologist Ajay Mehra. “Residents must stay flexible and expect the unexpected.”
Long-Term Takeaways and What Lies Ahead
Delhi’s weather this time of year serves as a powerful reminder of both the city’s resilience and vulnerability. Today’s intermittent rains, sticky warmth, and manageable AQI create a window for both improved air and seasonal challenges.
As October approaches: Expect decreasing rainfall, steadily cooler mornings, but also readiness for rising pollution as post-monsoon stubble burning begins in nearby states. For now, taking each day as it comes—and keeping an eye on trustworthy forecasts—is the best way forward.
