Weather in August
Temperature
The transition into August marks the average high-temperature at a still moderately hot 81.7°F (27.6°C), differing minimally from July's 82.4°F (28°C). Glasgow records an average nighttime low of 63.3°F (17.4°C) in August.Heat index
The heat index value during August is estimated at a tropical 87.8°F (31°C). Persistent activity under exposure might lead to a feeling of weariness, with subsequent heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
