From heavy rain in Kerala to hailstorms in Delhi: Here’s what the latest IMD forecast is warning travellers in India

India's monsoon story is entering a crucial phase, and travellers planning trips over the next few days may need to keep a close eye on weather updates before heading out. According to the India Meteorological Department's (IMD) latest All India Weather Summary and Forecast Bulletin issued on June 11, conditions are favourable for the southwest monsoon to advance further into several parts of the country, bringing with it heavy rainfall, thunderstorms, rough seas, and travel disruptions across multiple regions.The monsoon's northern limit currently stretches through parts of Maharashtra, Karnataka, Andhra Pradesh and eastern India, and is expected to advance into more areas over the next three to four days. For travellers, this means that the long-awaited rainy season is finally arriving in several destinations that become particularly appealing during the monsoon months. However, it also means adjusting plans according to weather advisories.The wettest conditions are expected in the eastern and northeastern parts of the country. IMD has forecast heavy to very heavy rainfall over Arunachal Pradesh, Assam and Meghalaya, Odisha, and Sub-Himalayan West Bengal and Sikkim on June 11. Heavy rainfall is also likely across Bihar, Andaman and Nicobar Islands, Gangetic West Bengal, Nagaland, Manipur, Mizoram and Tripura. These regions attract visitors for their lush landscapes and cultural experiences, but heavy rain can disrupt road journeys, increase travel times, and occasionally lead to landslides in vulnerable areas.Travellers planning visits to hill destinations in the northeast and eastern Himalayas should be particularly cautious. Sikkim and the Darjeeling region, which witness a surge in monsoon visitors eager to experience mist-covered mountains and tea estates, may experience periods of intense rainfall. The IMD has warned of localised flooding, waterlogging and reduced visibility in areas receiving heavy rain.Southern India is also expected to receive significant rainfall. Kerala and Mahe are likely to witness heavy to very heavy rainfall, while heavy rain has been forecast for Coastal Karnataka, Lakshadweep, Coastal Andhra Pradesh, Tamil Nadu and Puducherry. The southwest coast traditionally transforms into a vibrant monsoon landscape during this time of year, attracting travellers interested in Ayurveda retreats, backwater experiences and monsoon tourism. Yet the same conditions can lead to temporary disruptions in outdoor activities, ferry services and road transport.For those heading to Karnataka's coastal districts or Kerala's hill stations, flexibility in itineraries may prove useful. Travellers may want to prioritise indoor experiences, leave room for delays, and monitor local advisories before undertaking long drives through ghat sections, where heavy rain can occasionally trigger landslides or road closures.Meanwhile, northwestern India faces a different weather story. Delhi, Haryana, Punjab, Rajasthan, Uttar Pradesh and Uttarakhand are expected to witness thunderstorms accompanied by gusty winds over the coming days. The IMD has forecast thundersqualls with wind speeds reaching 60 to 70 kmph, gusting up to 80 kmph, in parts of Haryana, Delhi, Punjab, Rajasthan and Uttar Pradesh.Hailstorms are also likely at isolated places across Haryana, Delhi, Punjab, Himachal Pradesh, Uttarakhand, Jammu and Kashmir and parts of Uttar Pradesh. Such weather conditions can affect flight schedules, road travel and sightseeing activities. Visitors exploring heritage cities, mountain destinations or undertaking road trips in these regions may need to factor in sudden weather changes.The bulletin also indicates that isolated heat wave conditions are likely over West Rajasthan on June 11. While the desert state remains popular among domestic travellers even during summer, authorities advise avoiding prolonged exposure to the sun and staying adequately hydrated.For marine tourism and coastal activities, the IMD has issued important advisories. Fishermen have been advised not to venture into several parts of the Arabian Sea and Bay of Bengal between June 11 and 15 due to squally weather and strong winds. Affected areas include the Gulf of Mannar, Sri Lanka coasts, the Andaman Sea, south Bay of Bengal, and stretches along the Maharashtra, Goa, Karnataka and Kerala coasts. Travellers planning boat rides, island excursions or water-based activities in these regions should confirm operational status with local authorities and tour operators.Monsoon travel requires preparation and flexibility. Checking weather updates before departure, building buffer time into itineraries, avoiding unnecessary movement during severe weather events and following official advisories can significantly improve the travel experience.
