Humidity should be mentioned
It is worth mentioning humidity - at a given temperature the humidity level has a big effect on how hot or cold someone can perceive the temperature to be.
e.g. when humidity is high, sweat evaporates less readily and thus people cannot lose heat as quickly and so a person is likely to regard the conditions as hotter than at low humidity for the same recorded temperature.
This is why you can purchase / make wet bulb thermometers, which factor in evaporation and although their main use is to calculate humidity - they do allow an easy intuitive way to determine if the climate will be "comfortable" or not.
