Kolkata in September
Not the best time
Transitional month as monsoon retreats and festival preparations energize the city. Still wet but anticipation builds.
Weather
September sees the monsoon beginning its retreat, but humidity remains suffocating and intermittent heavy rains continue. The city starts preparing for festival season as weather slowly becomes more predictable. Temperatures stay warm but not scorching.

All Months
October through March is ideal — pleasant temperatures and clear skies. December and January are perfect, with highs around 25°C and cool evenings. This is also festival season with Kali Puja and Christmas celebrations. February brings spring and the famous Kolkata Book Fair. March starts getting warm but remains comfortable. Avoid April to September unless you enjoy 35°C+ heat and monsoon floods. The rains from June to September can be romantic but disruptive to sightseeing. October's post-monsoon freshness makes it a sweet spot for visiting.
