Weather in August
Temperature
Howell marks the arrival of August with an average high-temperature of a still tropical 87.6°F (30.9°C), hardly different from July's 89.2°F (31.8°C). The nights of August in Howell anticipate an average low-temperature of 70.3°F (21.3°C).Heat index
In August, the average heat index is computed to be a torrid 102.2°F (39°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.Note that heat index values are valued for light wind and location in the shade. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
