Weather in August

August, the last month of the summer in Calvin, is another warm month, with an average temperature ranging between max 84.7°F (29.3°C) and min 61.3°F (16.3°C).

Temperature

The arrival of August records an average high-temperature of a still moderately hot 84.7°F (29.3°C), closely related to the 85.1°F (29.5°C) observed in July. Calvin notes a substantial temperature decline from the daytime peaks throughout August, with an average nighttime temperature of 61.3°F (16.3°C).

Heat index

For most parts of August, the heat index is appraised at a very hot 95°F (35°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Remember, however, that not all shade structures offer full protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
