Weather in August
Temperature
The introduction of August notes a subtle temperature variation to a still moderately hot 82°F (27.8°C) from July's 83.3°F (28.5°C). Allerton experiences a consistent average temperature of 63.7°F (17.6°C) throughout the nights in August.Heat index
August's heat index is appraised at a tropical 87.8°F (31°C). Persistently participating in activities during exposure may lead to fatigue and induce heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. 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 'feels like' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
