Delhi Climate & Weather Averages

Climate Insights from Our Writers

“Delhi's data shows climate at its most extreme. May averages 33°C, January averages 14°C, but the felt extremes are far wider. I tracked a week in late June when the temperature hit 39°C with 60% humidity, and the air quality index pushed into the 'unhealthy' range. The city's continental climate creates one of the most dramatic seasonal transitions I've recorded, with temperatures swinging by 20°C between winter and summer. The summer months of April through June are intensely hot, with frequent heatwaves that can push temperatures above 45°C. The monsoon season from July to September brings relief from the heat but creates its own challenges with high humidity and flooding. The winter months of December through February are cool and pleasant during the day, with temperatures around 20°C, but the nights can be cold, dropping to 7°C. The real challenge of Delhi's winter is the air quality, which can deteriorate to hazardous levels due to a combination of agricultural burning, vehicle emissions, and temperature inversions that trap pollutants close to the ground. The best time for a visit is October through November and February through March, when temperatures are most comfortable and the air quality is typically better. The data shows that October is the ideal month, with temperatures around 25°C, low humidity, and clear skies. For travelers, the key is planning around the extremes — avoid the summer heat and the winter smog, and target the transitional seasons that offer Delhi at its most comfortable and accessible.”
