Dew Point Temperature — Explained India

The dew point is the temperature at which air must be cooled (at constant pressure) for water vapour to condense into dew or frost. It is a reliable indicator of actual moisture content in the air — unlike relative humidity, which changes with temperature.

Dew Point	Comfort Level	India Context
Below 10°C	Very dry, comfortable	Dry winter in North India
10–16°C	Comfortable	Pleasant weather
16–21°C	Slightly humid	Pre-monsoon
21–24°C	Humid, uncomfortable	Monsoon, coastal cities
24–26°C	Oppressive	Peak monsoon Mumbai/Chennai
Above 26°C	Severely humid	Kerala coast, NE India monsoon

What is a comfortable dew point in India?

A dew point below 16°C is comfortable for most people. Between 16–21°C feels slightly humid. Above 24°C (common in coastal India during monsoon) feels oppressive and sticky — outdoor activity becomes exhausting.

Dew point vs humidity — which is better for comfort?

Dew point is a better comfort indicator than relative humidity because it doesn't change when temperature changes. 70% humidity at 20°C feels comfortable; 70% humidity at 35°C feels extremely uncomfortable — but dew point correctly shows the difference.
