Weather in August
Temperature
Stepping into August, Upper Glasgow records an average high-temperature of a still warm 81.9°F (27.7°C), almost consistent with July. In the month of August, the nighttime temperature dips to a steady average of 63.9°F (17.7°C).Heat index
For most parts of August, the heat index is appraised at a tropical 87.8°F (31°C). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
