Relative humidity alone is misleading. The dew point — the temperature at which air saturates — is the honest measure of how muggy it feels and where clouds or condensation form. The wet-bulb temperature, always between dew point and air temperature, is what evaporative cooling can reach and a key limit for human survivability in extreme heat.
