August, the last month of the summer in Bolt, is also a moderately hot month, with temperature in the range of an average high of 82.4°F (28°C) and an average low of 58.6°F (14.8°C).

Temperature

The onset of August brings with it an average high-temperature of a still moderately hot 82.4°F (28°C), showing a negligible variation from the month before. Bolt experiences a substantial decline from the daytime high temperatures in August, settling on an average low of 58.6°F (14.8°C).

Heat index

August's heat index is estimated at a tropical 89.6°F (32°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. 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 'feels like' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are highly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
