Delhi Weather – Orange Alert Issued as Rain Brings Relief from Humidity
Delhi Weather – Delhi began Monday under warm, sticky weather conditions as the India Meteorological Department issued an orange alert for the capital, warning of moderate rainfall and a mostly cloudy sky during the day. The forecast comes after a spell of intense heat on Sunday, when temperatures rose sharply despite afternoon showers in several parts of the city and surrounding areas.
Sunday Marks Delhi’s Hottest July Day in Two Years
Delhi recorded a maximum temperature of 38.6 degrees Celsius on Sunday, making it the city’s hottest July day in nearly two years. The temperature was around two degrees above the normal level for this time of year. The previous higher July reading was recorded on July 11, 2024, when the mercury had reached 38.8 degrees Celsius.
Night-time conditions also remained uncomfortable. The minimum temperature was measured at 29.2 degrees Celsius, which was 1.3 degrees above the seasonal average. It was the highest minimum temperature recorded in July since July 2, 2024, when the city had reported 30.7 degrees Celsius.
Rainfall Recorded Across Delhi and Nearby Areas
Moderate rain during the afternoon offered temporary relief from the heat in several localities, though the showers also created waterlogging in some areas. Chhatarpur received the highest rainfall in Delhi-NCR, recording 49 mm of rain until 2.30 pm.
The rainfall led to water accumulation on roads in parts of Chhatarpur, affecting movement for commuters and local residents. Other areas in and around the capital also reported varying levels of rain during the day.
Gurugram received 35 mm of rainfall, while Mehrauli recorded 18 mm. Greater Noida reported 17 mm, followed by Najafgarh with 8 mm and Janakpuri with 7 mm. Humidity levels remained high despite the showers, with relative humidity touching 92 per cent at 5.30 pm.
IMD Forecasts Cloudy Sky and Moderate Showers
The weather department has forecast a generally cloudy sky for Monday, along with moderate rainfall in several parts of Delhi. The maximum temperature is likely to remain close to 32 degrees Celsius, while the minimum may settle around 27 degrees Celsius.
The orange alert indicates the possibility of weather-related disruptions, including waterlogging, traffic delays and reduced visibility in some locations during periods of rain. Residents have been advised to remain alert, particularly while travelling through low-lying areas and roads that are prone to flooding.
Delhi Air Quality Remains in Moderate Range
Delhi’s air quality continued to remain in the moderate category on Sunday evening. Data from the Sameer app showed that the Air Quality Index stood at 155 at 8 pm.
According to the Central Pollution Control Board, AQI readings between 101 and 200 are classified as moderate. Such air quality levels may cause discomfort for people who are unusually sensitive to pollution, while most residents are unlikely to face major health concerns.
Monsoon Trough Expected to Move Towards North India
Weather experts said the recent mix of heat, humidity and scattered rainfall is linked to changes in the seasonal monsoon trough. The trough has shifted towards central India because of a low-pressure system over Odisha and an associated cyclonic circulation extending across parts of Madhya Pradesh and south Sindh.
The system is expected to gradually move back towards Delhi and the Indo-Gangetic plains over the next few days. This shift could bring more widespread monsoon rainfall to Delhi-NCR and improve the consistency of seasonal showers across northern India.
