The Average onset date of monsoon across Asia varies across the region due to its diverse geography and climatic conditions. The monsoon is a seasonal wind pattern that brings heavy rainfall to much of South and Southeast Asia during the summer months. The onset of the monsoon is a highly anticipated event as it marks the beginning of the rainy season, crucial for agriculture and water resources in many countries.

In India, the onset of the monsoon typically occurs around late May to early June, starting from the southern state of Kerala and gradually advancing northward over the course of a few weeks. However, the exact onset date can vary from year to year and is influenced by various factors such as atmospheric conditions, ocean temperatures, and the presence of weather phenomena like El Niño or La Niña.

Similarly, in other parts of Asia such as Bangladesh, Myanmar, Thailand, and Vietnam, the monsoon onset typically occurs around the same time, although the exact dates may differ. In some regions, such as the Philippines and parts of Indonesia, the onset of the monsoon can occur earlier or later depending on local climate patterns.

Understanding the average onset date of the monsoon is essential for farmers, policymakers, and disaster management agencies to prepare for the impacts of heavy rainfall, flooding, and other associated risks. Timely and accurate predictions of the monsoon onset are therefore important for planning agricultural activities, managing water resources, and mitigating the potential effects of extreme weather events.
