Create a free accountMay 2025 was the wettest since records began in 1901, with pan-India rainfall 106% above its long period average.
Detailed Explanation
In May 2025, India experienced unprecedented rainfall, making it the wettest month on record since 1901. This amount was significantly above the average rainfall levels that have been recorded over many years (106% more than the long-term average). This indicates not just a normal rainy month but an extreme weather event that stands out in the historical context of Indian rainfall.
Examples & Analogies
Imagine your city's average rainfall is usually about 100mm in May. If suddenly it rains 206mm, that would be like having a surprise extra-large rainstorm compared to what you're used to. Just like unexpectedly getting a colossal birthday cake would surprise you, this rainfall level is an extraordinary event for the country.

Detailed Explanation
To better understand where and how this exceptional rainfall occurred, the India Meteorological Department (IMD) provides detailed summaries that break down the rainfall data into various categories such as districts, states, and sub-divisional levels. This granularity helps in analyzing the impact of rainfall on different regions and is essential for both planning and response strategies.
Examples & Analogies
Think of it like a school report card that not only shows your overall grades but also breaks them down into subjects like math, science, and history. Just as teachers use those details to help students improve, meteorologists use these detailed rainfall summaries to help regions prepare better for weather events.

Detailed Explanation
The data reveals specific regional rainfall amounts for May 2025. The all-India average rainfall was 126.7mm, which is the highest amount on record. Central India and the South Peninsular regions also saw significant rainfall, with Central India recording 100.9mm and South Peninsular India 199.7mm, marking it as the second highest on record. This information emphasizes the variability and intensity of rain in different regions during this anomalous weather event.
Examples & Analogies
If you think of each region like different classrooms in a school, while the entire school had a record number of students (rain) showing up, some classrooms (like Central India) had a high number of students but not the highest. Others (like the South Peninsular region) had a second-highest attendance, showing how each section had its unique level of 'attendance' during this record rain event.
