Weather in August
Temperature
During August, Helvetia observes a subtle ascent to a still moderately hot 80.8°F (27.1°C) from July's 82°F (27.8°C) in the average high-temperature. Helvetia experiences a substantial divergence from daytime highs in August, with average lows hovering around a mild 58.5°F (14.7°C).Heat index
The heat index value during August is evaluated at a hot 86°F (30°C). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
