Conversely, days that are cloudy are generally associated to be cooler. However, it is possible for temperatures to reach above 30 degrees Celsius on cloudy days. The amount of moisture in the air and the amount of wind affect the comfort level and therefore also affects peoples perceptions of temperature. This will be discussed in the section on humidity. The higher the percentage of moisture in the air, the warmer it may feel.
Wind affects perceptions of temperature particularly with lower temperatures.
The higher the wind strength, the colder it may feel. A person riding a bicycle on a cold calm morning will experience a 'relative breeze' that will make it feel colder than when not moving. For instance, if the temperature rises rapidly it will feel warmer than what you may estimate. On a day when the temperature remains fairly constant throughout the day, it may feel that the temperature is actually falling. You normally will obtain the best estimates of temperature on days where the temperature rises and falls normally.
