There's something about Mumbai during monsoon that feels like the city is briefly honest with itself. I arrived in July expecting chaos and found poetry — kids playing in flooded streets, chai stalls steaming in the rain, the Arabian Sea churning against Marine Drive. The data says June-September brings 2,200mm of rain; what it can't capture is the joy. November-February is when the city reawakens dry and pleasant at 28°C — the cultural calendar fills up. March-May is harsh: 35°C with 75% humidity. Diwali (October-November) is when Mumbai shines brightest.
