August 2025 has etched itself into India‘s meteorological history books as one of the wettest months in decades. With rainfall of 268.1 mm, August 2025 ranks as the 7th highest since 2001 and holds the 45th position since records began in 1901, according to the India Meteorological Department (IMD). This unprecedented monsoon activity has reshaped weather patterns across the subcontinent, bringing both relief and challenges to different regions.

What Triggered This Monsoon Surge?
IMD Director General Mrityunjay Mohapatra explained that India experienced intense monsoon activity during the latter half of August 2025, triggered by the formation of four low-pressure systems over a span of fifteen days. This unusual concentration of weather systems significantly boosted seasonal rainfall across multiple regions.
The meteorological phenomenon represents a classic example of how atmospheric dynamics can create exceptional weather patterns. These low-pressure systems acted like moisture magnets, drawing water vapor from the Arabian Sea and Bay of Bengal, transforming it into the record-breaking rainfall India experienced.
Temperature Records Amid Heavy Rains
Interestingly, August 2025 wasn’t just about rainfall records. The month recorded an average maximum temperature of 31.08°C (22nd highest since 1901), average minimum temperature of 23.96°C (7th highest since 1901), and a mean temperature of 27.52°C (15th highest since 1901). These statistics reveal how heavy rainfall coincided with relatively warm temperatures, creating humid conditions across the country.
Regional Impact Analysis
Northwest India emerged as the biggest beneficiary, receiving its highest August rainfall since 2001. States like Punjab, Haryana, and Rajasthan, traditionally dependent on monsoons for agriculture, witnessed exceptional showers that could boost crop yields significantly.
South Peninsula wasn’t far behind, with rainfall figures marking the third-highest levels since 2001. This surge particularly benefited Karnataka, Andhra Pradesh, and Tamil Nadu, regions crucial for India’s agricultural output.
Major Cities:
- Delhi recorded 399.8 mm rainfall, making it the wettest August in 15 years
- Mumbai saw 1075.5 mm rainfall, well above the usual 585.2 mm, marking the second-highest August total in 15 years
September Forecast: Extended Monsoon Activity
For September, IMD has forecast above-normal rainfall across most regions, with some areas in northeast and east India, parts of extreme southern peninsula, and pockets in northwest India potentially experiencing below-normal showers.
This extended monsoon activity aligns with recent climate patterns showing delayed withdrawal of monsoon systems from the Indian subcontinent.
Delayed Monsoon Withdrawal: A New Normal?
When questioned about monsoon withdrawal, IMD DG Mohapatra noted there’s no immediate forecast for it, explaining a noticeable trend of 15-day delay in monsoon withdrawal, now typically occurring around September 17 instead of September 1.
This shift reflects broader climate change impacts on India’s monsoon patterns, with implications for agriculture, water resource management, and flood preparedness across the country.
Impact on Agriculture and Economy
The exceptional August rainfall brings mixed implications:
Positive Impacts:
- Enhanced reservoir levels across drought-prone regions
- Improved soil moisture for Rabi crop preparation
- Reduced irrigation costs for farmers
Challenges:
- Potential waterlogging in urban areas
- Risk of crop damage due to excessive moisture
- Transportation disruptions in heavily affected regions

Frequently Asked Questions
Q1: Why did India experience such heavy rainfall in August 2025?
A1: India’s exceptionally heavy August 2025 rainfall was caused by the formation of four low-pressure systems within fifteen days during the second half of August. According to IMD Director General Mrityunjay Mohapatra, these systems created “active to vigorous monsoon conditions” that significantly boosted seasonal rainfall across multiple regions, resulting in 268.1 mm of rainfall – the 7th highest August total since 2001.
Q2: How does August 2025 rainfall compare to historical records and what does this mean for September?
A2: August 2025 ranks as the 7th highest rainfall month since 2001 and 45th highest since 1901. Northwest India saw its highest August rainfall since 2001, while South Peninsula recorded the 3rd highest. IMD forecasts continued above-normal rainfall for September 2025, with monsoon withdrawal delayed by approximately 15 days compared to traditional patterns, now expected around September 17 instead of September 1.
