The monsoon trough and its oscillation remain the main triggers for rainfall in Delhi during this month. The trough is currently positioned far to the south of the capital and is likely to retain this position until 22nd August 2025. Thereafter, a monsoon system forming in the Bay of Bengal is expected to track deep into Rajasthan around the weekend of 23rd–24th August. The remnant system will also gain latitude and drag the trough along. The trough will then shift northward and pass in close proximity to Delhi on 23rd and 24th August. Between Monday and Friday, showers will generally be sporadic and short-lived, but the intensity and spread will increase substantially on Saturday and Sunday, 23rd–24th August 2025. Day and night temperatures are likely to remain under 35°C and 25°C respectively during the week.
