What time of day does condensation occur?

Dew only occurs when temperatures drop and objects cool down. Unlike hot air, colder air is less able to hold water vapor, which forces the gaseous water around cool objects to condense. Temperatures reach the dew point most usually at night – and especially during summer when warm days are followed by cool nights.
