The last month of the summer, August, is another warm month in Madison, Maryland, with an average temperature fluctuating between 83.1°F (28.4°C) and 69.4°F (20.8°C).

Temperature

The shift to August signals an average high-temperature of a still moderately hot 83.1°F (28.4°C), subtly varied from July's 84.6°F (29.2°C). During August, Madison records an average temperature of 69.4°F (20.8°C) at night.

Heat index

August's heat index is calculated to be a tropical 91.4°F (33°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
