Weather alerts, political developments and observances will be among the key areas to watch on September 3, 2026, with the India Meteorological Department (IMD) forecasting widespread rainfall across several parts of the country.

The latest IMD forecast indicates widespread to fairly widespread rainfall in regions including West Madhya Pradesh, East Madhya Pradesh, Chhattisgarh, parts of north India and the Northeast. Heavy rainfall is also expected in several areas during the period. 

Rain Forecast Across Several States

The IMD has forecast widespread rainfall over West Madhya Pradesh from September 3 to 6, while East Madhya Pradesh is expected to receive widespread rainfall through September 5. Chhattisgarh is also likely to experience widespread rainfall during the first week of September. 

The weather department has separately forecast widespread rainfall over Haryana, Chandigarh and Delhi from September 3 to 4 and over West Uttar Pradesh from September 3 to 5. East Rajasthan is also expected to receive isolated to scattered rainfall, with heavy rain possible on September 3 and 4. 

In eastern and northeastern India, rainfall activity is expected to continue over parts of Bihar, West Bengal, Sikkim and the northeastern states. The IMD has also warned of heavy rainfall in some areas, including Sub-Himalayan West Bengal and Sikkim. 

Madhya Pradesh Under Rain Watch

Madhya Pradesh remains among the regions receiving significant attention in the latest forecast. West Madhya Pradesh is expected to see fairly widespread to widespread rainfall from September 3 onward, while East Madhya Pradesh is also forecast to receive widespread rainfall.

The IMD's earlier extended forecast had indicated the possibility of isolated very heavy rainfall over West Madhya Pradesh during September 3–5. 

Residents should follow local weather warnings issued by the respective IMD meteorological centres, particularly in areas vulnerable to waterlogging, flooding and disruptions caused by heavy rain.

Wind Warning Along Coastal Areas

The 65-kmph wind figure should be interpreted in its proper context. An IMD warning for September 3 indicates squally winds of 45–55 kmph, gusting to 65 kmph, along and off the Somalia coast, parts of the westcentral and southwest Arabian Sea and a few areas of the Gulf of Mannar. The warning is primarily relevant to marine and fishing activities.

It should therefore not be described as a 65-kmph wind warning covering all 19 states.

Political Activity to Watch

Political developments will also remain in focus on September 3. The Bahujan Samaj Party, led by Mayawati, has been holding organisational meetings as it prepares for upcoming political challenges, particularly in Uttar Pradesh.

Recent BSP activity has included a state-level meeting in Lucknow chaired by Mayawati, while the party has also announced plans for a large programme on October 9 to mark the death anniversary of founder Kanshi Ram. 

Any specific claim regarding a major all-India BSP meeting on September 3 should be confirmed through an official party statement before being reported as a scheduled event.

Merchant Navy Day

September 3 is also observed as Merchant Navy Day in the United Kingdom. The day commemorates merchant seafarers and recognises the contribution made by merchant shipping, including during wartime.

The observance highlights the importance of merchant fleets in transporting essential goods and supporting international trade.

Other September 3 Updates

September 3 will also see several technology, academic and cultural programmes across India. The Genomics India Conference 2026 in Bengaluru, EV India Expo 2026 in Greater Noida and Esri India User Conference 2026 in New Delhi are all scheduled to conclude on or around the date.

Digital India has also scheduled programmes including a State Awareness Workshop in Gangtok and a DPDP Act workshop for NCERT officers, making digital governance and technology another area of interest on the day's calendar.

September 3, 2026, will be observed as Thursday and will feature a mix of international observances, cultural events, technology programmes, religious traditions and notable moments from history. In India, the day falls during Krishna Paksha Saptami, while several conferences and exhibitions will also conclude on the same date.

From Skyscraper Day and Merchant Navy Day to the closing day of major technology events, September 3 offers several topics of interest for readers tracking important days and events.

National Skyscraper Day

National Skyscraper Day is observed on September 3 to recognise the development of tall buildings and the engineering and architectural advances that made modern skyscrapers possible. The date is associated with architect Louis Sullivan, who was born on September 3, 1856, and is widely regarded as an influential figure in the development of modern high-rise architecture. (Skyscraper Day)

The day provides an opportunity to look at the evolution of high-rise construction, from early steel-frame buildings to today's supertall structures.

Merchant Navy Day

Merchant Navy Day is observed in the United Kingdom to remember the contribution and sacrifices of merchant seafarers, particularly those who served during wartime. The observance is also recognised in some other countries. (There is a Day for That!)

The day highlights the role of merchant shipping in transporting essential goods and supporting national economies and wartime logistics.

International Cabernet Day

September 3, 2026, also falls on International Cabernet Day, an annual observance associated with Cabernet Sauvignon. The day is observed on the Thursday before the US Labor Day holiday and is intended to celebrate the grape variety and its place in wine culture. (National Today)

Shitala Satam and Panchang

For India, September 3 falls under Krishna Paksha Saptami. In the Gujarati calendar tradition, the day is observed as Shitala Satam, dedicated to Goddess Shitala. The observance follows Randhan Chhath, when food is traditionally prepared in advance for the following day. (Drik Panchang)

Panchang calculations show Saptami continuing until the early hours of September 4, while Krittika Nakshatra continues until around 12:29 am on September 4 in several Indian city calculations. Exact sunrise, sunset and other muhurat timings vary by location. (Drik Panchang)

The date comes just one day before Krishna Janmashtami, which will be observed on September 4, 2026.

Technology Events Conclude

September 3 will also be the final day of several technology and industry events in India. The Genomics India Conference 2026 in Bengaluru is scheduled to hold its main conference on September 2 and 3, following a pre-conference workshop on September 1.

The EV India Expo 2026 in Greater Noida is also scheduled from September 1 to 3, bringing together electric mobility and related automotive technologies. The Esri India User Conference 2026 in New Delhi is scheduled for September 2 and 3, focusing on GIS and location-based technologies.

Other Events in India

Several other programmes are scheduled around the date, including the Sukoon Unplugged – The Jogi Experience live music event. An international conference on Indian Scientific Heritage at K.J. Somaiya Institute in Mumbai is also scheduled to conclude on September 3.

These events add cultural, academic and entertainment activities to the day's calendar alongside the technology conferences and exhibitions.

Moon and Pleiades

Skywatchers in parts of the world may also have an opportunity to observe the Moon near the Pleiades star cluster around September 3. In Indian astronomical terminology, the Pleiades are associated with Krittika Nakshatra. Panchang calculations for September 3 show the Moon passing through Krittika during the day and into the following night. (Drik Panchang)

Visibility of the conjunction will depend on location, local weather and the time of observation.
