Weather in August
Temperature
The arrival of August brings an average high-temperature of a still hot 87.3°F (30.7°C), closely following the temperature pattern of July. Saint Robert sees an average low-temperature of 65.8°F (18.8°C) during August.Heat index
August's mean heat index is calculated to be a very hot 100.4°F (38°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', quantifies the warmth felt when relative humidity is considered. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Shield from overexposure. Defense against sun-related harm is required. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
