Rain season
Monsoon June–September delivers around 80% of the city's 1,600mm annual rain, with July and August the most intense months. Pre-monsoon Kalbaisakhi (nor'westers) in April–May are violent convective storms that form rapidly in the afternoon — fast-moving and brief but often destructive. Humidity stays high June–October, making overcast days feel heavier than the rainfall totals suggest.
