Weather in August
Temperature
The high-temperature average in August for Heidelberg is a still hot 91.6°F (33.1°C), staying closely aligned with July's conditions. Throughout the month of August, Heidelberg expects an average low of 72°F (22.2°C).Heat index
August's average heat index is evaluated at a life-threatening hot 114.8°F (46°C). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. 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 remain especially vital for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
