Kanpur Weather Update: September 2026 Showers and Monsoon Climate Analysis

Recent Rainfall and Temperature Trends

On 23 September 2026, Kanpur experienced a pattern of intermittent rainfall that provided temporary relief but maintained high humidity. According to reports from the Times of India, the city saw two distinct spells of rain: a moderate-to-heavy morning shower and a lighter evening spell.

The morning rainfall was most significant at the Air Force Station, which recorded 38.4 mm, while Naubasta received 32.9 mm. Other city areas saw between 6.9 mm and 9.1 mm. A subsequent evening spell added another 5.8 mm of precipitation. Despite these showers, the temperature remained high; the maximum was recorded at 33.6°C, only 0.8°C lower than the previous day, while the minimum rose to 25.6°C.

Humidity and the 'Sultry' Effect

A critical factor in the weather kanpur experience during this period was the relative humidity, which peaked at 92%. This high moisture level, combined with bright sunshine between rain spells, created sultry conditions during the afternoon. Weather experts from the CSA observatory indicate that such intense humidity typically persists whenever the sun emerges during the wet season.

Understanding Kanpur's Humid Subtropical Climate

To put these recent events in context, Kanpur's climate is classified as humid subtropical (Cwa), bordering on a hot semi-arid climate. As detailed by Wikipedia, the city typically sees annual precipitation between 865–900 mm. The vast majority of this rainfall (750–800 mm) occurs during the southwest monsoon, which generally enters the region around 20–23 June and withdraws between the last week of September and the first week of October.

The rainfall observed on 23 September is characteristic of the late monsoon phase. While the showers are pleasant, the city's geography in the flat Indo-Gangetic Plains often results in the high humidity and temperature swings seen in late September.

Short-term Forecast

Looking ahead from the September 23 report, CSA weather expert S N Sunil Pandey suggested that cloud movements could lead to further thunderstorms, accompanied by gusty winds and light rain or drizzle over the following three days.
