June 30, 2026 Weather Forecast: Severe Heatwave Alert in North India, Heavy Monsoon Rains Batter Mumbai and the Northeast

The Southwest Monsoon is currently displaying a dual character across the Indian subcontinent. While the monsoon winds have firmly established their presence and are delivering heavy downpours in several states, large parts of North India are still reeling under severe heatwave conditions. According to the latest comprehensive weather forecast released by the India Meteorological Department (IMD) for June 30, 2026, the weather patterns across the country will be highly contrasting.

A strict alert for heavy to very heavy rainfall has been issued for the Northeastern states and the Western coastline, while residents of Delhi-NCR and neighboring Northern states will have to endure scorching heat and high humidity. Here is a detailed, region-wise breakdown of the weather forecast across India based on E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) standards.

North India: Heatwave Conditions and High Humidity

There is currently no significant respite in sight for the residents of North India, as soaring temperatures continue to dominate the region.

• Delhi, Haryana, and Chandigarh: A severe heatwave alert remains active for the national capital and its adjoining areas on June 30. The maximum daytime temperature is expected to hover dangerously between 38°C and 40°C, while the minimum temperature will settle around 28-30°C. Despite partly cloudy skies, the weather will remain highly humid. There is a possibility of light, scattered rain or thunderstorms accompanied by gusty winds blowing at 40-60 km/h during the late afternoon or evening, which may temporarily spike humidity levels rather than cool the air.
• Uttar Pradesh: The eastern pockets of the state will continue to experience intense heatwave conditions. Conversely, Western UP might see light to moderate rainfall accompanied by thunderstorms, though the oppressive, muggy weather will persist throughout the day.
• Rajasthan and Punjab: The weather in these border states will remain predominantly dry and exceptionally hot. Temperatures are highly likely to cross the 40°C mark. Isolated areas may experience sudden dust storms or very light, sporadic drizzles.

Northeast and East India: Torrential Rainfall and Flood Alerts

The monsoon is currently performing at its peak in Northeast India, prompting the meteorological department to issue high-level alerts for potential disasters.

• Assam, Meghalaya, Sikkim, and Sub-Himalayan West Bengal: These regions are bracing for heavy to extremely heavy rainfall, with estimates ranging from 7 to 20 centimeters. Relentless torrential rains have significantly elevated the risk of severe waterlogging in low-lying areas, flash floods, and dangerous landslides in the hilly terrains. Thunderstorms and frequent lightning strikes are also anticipated.
• West Bengal (Kolkata) and Odisha: Skies will remain generally overcast in these states. Residents can expect light to moderate rainfall accompanied by thunderstorms. The maximum temperature will range between 35°C and 38°C, creating a slightly sticky and humid atmosphere.
• Bihar and Jharkhand: Both states will witness a mixed bag of weather. Moderate to heavy rainfall is expected in isolated pockets, which will bring immense relief to the farming community actively preparing for Kharif crop sowing.

West India: Active Monsoon Over Mumbai and the Konkan Coast

Monsoon winds are aggressively advancing across Maharashtra and neighboring coastal regions, bringing substantial showers.

• Maharashtra and Goa: The Konkan belt, Goa, and Madhya Maharashtra are highly likely to receive heavy to very heavy rainfall on June 30. The monsoon is exceptionally active over India’s financial capital, Mumbai, and its sprawling suburbs. An alert for intense rain and thunderstorms has been issued, and civic authorities have advised residents to stay cautious regarding potential waterlogging in flood-prone, low-lying areas.
• Gujarat: While some localized parts of Gujarat will experience light to moderate showers, the overall weather across the state will remain mixed and relatively calm compared to neighboring Maharashtra.

South India: Widespread Coastal Showers

The performance of the monsoon clouds over the Southern Peninsula remains robust and consistent.

• Kerala and Karnataka: The monsoon is fully active across both states. Heavy to very heavy rainfall is strongly predicted, particularly for Coastal Karnataka and the South Interior Karnataka regions.
• Bengaluru: The IT capital of India will continue to enjoy pleasant weather. Skies will be partly cloudy with a high probability of light, refreshing rain. The maximum temperature will range from 28°C to 30°C, and the minimum will be between 20°C and 22°C, keeping the climate comfortable albeit slightly humid.
• Chennai and Hyderabad: The weather in these metropolitan cities is expected to be warm and humid. However, light rainfall or scattered evening showers are anticipated, which will help keep the maximum temperatures in check between 33°C and 37°C.

The Himalayan Region: Weather in the Mountains

In the higher altitudes of Jammu and Kashmir, Himachal Pradesh, and Uttarakhand, light to moderate rainfall is expected, with a rare possibility of light snowfall in the uppermost peaks. In the lower valleys and plains of these states, the weather will remain pleasant with occasional thunderstorms. Tourists are advised to check local weather updates before planning travel routes.

Comprehensive IMD Health and Safety Advisory

• Heatwave Precautions (North India): To protect yourself from the severe heatwave, it is crucial to stay hydrated. Drink plenty of water, fresh fruit juices, or ORS throughout the day. Avoid direct exposure to the sun during peak afternoon hours (12 PM to 4 PM).
• Flood and Waterlogging Safety (Northeast & West Coast): Residents in heavy rainfall zones must remain vigilant against sudden waterlogging and traffic disruptions. Avoid traveling to hilly regions prone to landslides until the weather clears.
• Alert for Farmers: The farming community is advised to plan their agricultural activities, pesticide spraying, and irrigation schedules strictly according to local IMD alerts to protect their crops from extreme weather.
