The southwest monsoon withdrew from Delhi on 23rd September, a little ahead of the scheduled date of 25th September. Even after the retreat of the monsoon, the capital city witnessed scattered showers last Saturday. The sky turned overcast today as well, and conditions were favourable for light rainfall. All this is the after-effect of the weather system that earlier deluged Uttar Pradesh.

The low-pressure area has now weakened, but the remnant cyclonic circulation still remains in the lower levels. The presence of the circulation and the passage of a western disturbance across the mountains together resulted in conducive conditions. However, the clouds are likely to wither as the day progresses, and no significant rainfall is expected through the day. Under the influence of the low-pressure area and western disturbance, Delhi observed pleasant weather conditions over the weekend, with temperatures dipping appreciably below normal.

The day temperature had dropped below 30°C on Saturday when the base station Safdarjung recorded a maximum temperature of 29.2°C, about 5°C below normal. This was the third time this month when the mercury dipped below 30°C. The lowest temperature of 27.6°C was recorded on 05th September 2026, followed by 29.1°C on 06th September 2026. The maximum temperature is likely to rise and cross 30°C today, while still remaining below normal. A rise in mercury is expected through the week, reaching about 35°C over the weekend.

The minimum temperature has also been dropping below normal for the last few days. Yesterday, on Sunday, the minimum touched 21°C, the first time in September in 18 years. Earlier, the lowest temperature of 20.8°C was registered on 06th September 2008. The minimum temperature is also likely to rise by 2°-3°C during the next 3-4 days.

The circulation over Uttar Pradesh will break up along the foothills of West Uttar Pradesh. The western disturbance will clear the mountains in about the next 36 hours. The wind pattern will become steady, and the lower-level winds will turn strong northwesterly from tomorrow onwards, typical of a post-monsoon feature.

No significant weather system is expected over North India through the week. The seasonal anticyclone will strengthen over Rajasthan and adjoining parts. This will facilitate mostly clear skies, moderate winds, a slight nip in the air, and improved visibility conditions.
