Weather Update August 12, 2026: Monsoon activity remains intense across several parts of India, with heavy rainfall, thunderstorms and gusty winds expected in multiple states on Wednesday, August 12. Delhi, Uttar Pradesh, Bihar, Rajasthan, Uttarakhand and several other regions may experience spells of heavy rain, while hilly areas could face an increased risk of landslides.
According to the forecast details, thunderstorms accompanied by strong winds could affect several regions. Wind speeds may reach 60-90 kmph at isolated places, although the intensity will vary considerably from one state and district to another.
Residents should keep track of the latest district-level warnings from the India Meteorological Department (IMD), as weather alerts can be revised depending on changing conditions.
Rain, thunderstorms or other adverse weather conditions are expected across parts of these states and Union Territories:
The severity of rainfall and wind will not be uniform across all these regions. Some places may receive intense showers, while others could see thunderstorms and shorter spells of rain.
Active monsoon conditions and weather systems over and around the country are contributing to the current spell of rainfall.
A cyclonic circulation over the northwest Bay of Bengal and adjoining areas is among the systems influencing weather conditions. Such systems can increase moisture supply and support widespread rainfall and thunderstorms over central, eastern and northern India.
People in vulnerable areas should also remain alert to lightning, localised flooding, waterlogging and strong wind gusts.
Delhi could experience rain and thunderstorms on August 12. Gusty winds may accompany some spells of rain.
Expected conditions in Delhi:
| Weather Parameter | Forecast |
|---|---|
| Maximum temperature | Around 36°C |
| Minimum temperature | Around 29°C |
| Wind speed during thunderstorms | Around 30-40 kmph |

Heavy rainfall in the hills can trigger landslides, falling rocks and temporary road closures. Tourists should check road and local weather conditions before heading into vulnerable mountainous areas.
Rain and thunderstorms are also expected in parts of Himachal Pradesh, including Chamba, Kangra, Kullu, Mandi, Solan, Bilaspur, Kinnaur, Lahaul-Spiti and Sirmaur.
Strong winds of around 60-65 kmph could occur in some areas during thunderstorms.

Several districts of Rajasthan could also experience heavy rainfall and thunderstorms, including Bundi, Chittorgarh, Bhilwara, Tonk, Sawai Madhopur, Baran, Kota, Pali, Bikaner, Udaipur, Jaipur, Ajmer and Bharatpur.
Some thunderstorms could produce strong wind gusts. Jaipur's temperature is expected to remain around 33°C maximum and 26°C minimum.
During thunderstorms, avoid standing under isolated trees, electricity poles or weak structures. People in flood-prone locations should stay away from overflowing drains and waterlogged underpasses.
In mountainous regions, avoid unnecessary travel during intense rainfall because landslides and falling debris can block roads with little warning. Farmers should also secure harvested crops and lightweight equipment if strong winds are forecast.
Because thunderstorm and heavy-rain warnings can change quickly, check the latest IMD nowcast and district-level alerts before travelling.
