Weather Forecast for August 12, 2026: The monsoon is expected to remain active across large parts of India on Wednesday, August 12, with heavy rainfall, thunderstorms, lightning and strong winds forecast across several states.

According to the weather update, around 19 states and Union Territories, including Delhi, Uttar Pradesh, Bihar, Rajasthan, Madhya Pradesh, Uttarakhand and Himachal Pradesh, could experience intense spells of rain. Wind speeds during thunderstorms may become particularly strong in some regions, with gusts potentially reaching up to 90 kmph.

The combination of heavy rainfall and strong winds could lead to waterlogging, traffic disruption, falling trees and damage to weak structures. In the Himalayan region, prolonged rainfall may also increase the risk of landslides and flash floods.

People planning to travel on August 12 should therefore keep track of local weather advisories, particularly in areas under heavy-rain warnings.

Heavy Rain Alert Across 19 States

The weather outlook indicates rain and thunderstorm activity across:

Uttar Pradesh, Delhi, Bihar, Haryana, Rajasthan, Uttarakhand, Himachal Pradesh, Punjab, Jammu and Kashmir, Jharkhand, West Bengal, Odisha, Madhya Pradesh, Chhattisgarh, Gujarat, Maharashtra, Telangana, Andhra Pradesh and Kerala.

What Is Driving the Heavy Rain?

Several weather systems are influencing the monsoon pattern.

An upper-air cyclonic circulation is present over the northwestern Bay of Bengal and adjoining areas, while a low-pressure system around northeastern Madhya Pradesh and neighbouring Chhattisgarh is supporting rainfall over central India.

The monsoon trough and other atmospheric circulations are also helping maintain widespread rainfall activity.

These systems could keep weather conditions unstable across northern, central, eastern and western parts of the country.

August 12 Temperature Forecast for Major Cities

Strong Winds, Lightning and Landslides: What People Should Watch For

Heavy rain is not the only concern on August 12. Thunderstorms may bring damaging wind gusts and frequent lightning in some regions.

People should avoid taking shelter under isolated trees during thunderstorms and stay away from damaged electric poles or exposed wires. Farmers may need to take precautions to protect harvested crops and livestock from intense rain and wind.

In mountainous regions, avoid unnecessary travel through landslide-prone roads during periods of intense rainfall.

Fishermen should also follow official advisories before entering areas where rough weather or strong winds have been forecast.

Weather Alerts Can Change Quickly

Monsoon systems can intensify, weaken or shift location within a few hours. A district that is under a moderate warning in the morning could face stronger weather later in the day, while rainfall may also move away from some areas.

People should therefore check the latest IMD nowcast, district-level warning and local administration advisories before travelling on August 12.
