When the rains come
The southwest monsoon usually reaches the Konkan coast and Mumbai in the first half of June and retreats during late September and October. The timing shifts by a week or two most years. The coast and the Western Ghats get very heavy rain; the Deccan interior around Pune, Chhatrapati Sambhajinagar and Nashik gets much less.
Where the monsoon shines
- Ghats and hill stations: Lonavala, Malshej Ghat, Bhandardara, Amboli and Igatpuri for mist, waterfalls and green valleys.
- Forts: easier forts such as Sinhagad and Lohagad for cloud views, with care on wet steps.
- The Kaas plateau near Satara: a wildflower plateau that blooms roughly from late August to early October. Visits in the flowering season usually need an advance slot, so check the official booking arrangements.
- Ajanta: waterfalls in the gorge and greener surroundings in late monsoon.
What may be closed or disrupted
- Beach water sports and boat trips to sea forts are generally suspended.
- Harbour ferries, including some Mumbai to Alibag services, usually stop or are reduced.
- The Matheran toy train is often limited or suspended.
- Some waterfalls, dams and forts are closed to visitors by local orders after accidents or during heavy rain.
- Mumbai local trains and roads can be disrupted for hours after very heavy rain.
- Ghat roads can close after landslides.
Staying safe
- Watch the forecast and alerts. The India Meteorological Department issues coloured district warnings. On orange or red alert days, postpone treks and ghat drives.
- Keep away from fast water. Don't enter streams, waterfall pools or flooded causeways. Water levels can rise very quickly.
- Treat cliffs and rock steps with caution. Wet rock, moss and fog cause most monsoon accidents in the hills.
- Avoid wading through floodwater. Besides currents and open drains, it carries a risk of infections such as leptospirosis.
- Travel by daylight. Ghat roads are harder in rain and fog after dark.
- Avoid peak weekends. Popular spots near Mumbai and Pune can be dangerously crowded on rainy Sundays.
What to pack
- A good rain jacket, or a poncho that covers your bag.
- Shoes or sandals with grip that you don't mind getting soaked.
- Quick-drying clothes and a spare set in a dry bag.
- Zip bags for your phone, documents and cash.
- Insect repellent.
Festivals in the season
Ganesh Chaturthi, usually in August or September, is Maharashtra's biggest festival. Mumbai and Pune fill with elaborate pandals and processions, especially on the immersion days. It is unforgettable but crowded, and traffic is disrupted, so plan around the main dates. Dahi Handi, earlier in the season, sees human pyramids in the streets.
