Relative humidity is a function of air temperature. 50% humidity at 60F is relatively comfortable, but 50% humidity at 90F is much more uncomfortable. What is really happening is the dew point is closer to your ambient surface skin temp, so water has a harder time evaporating/starts to collect. Since air holds more water at higher temps (and a lot more, 90F air can hold almost 3x as much as 60F air), just comparing humidities without considering temp doesn't say much.
