August, the last month of the summer in Morrisonville, is also a hot month, with temperature in the range of an average low of 74.5°F (23.6°C) and an average high of 91.2°F (32.9°C).

Temperature

The warmest period is usually observed in July and August, with the average high-temperature peaking at 91.2°F (32.9°C).

Heat index

Throughout August, the heat index is calculated to be a blazing hot 116.6°F (47°C). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.
Keep in mind the heat index values are meant for areas in shade and with light wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
