Weather in August
Temperature
As Winterthur steps into August, the average high-temperature holds at a still warm 82.9°F (28.3°C), hinting at a minor fluctuation from the prior month. Winterthur, during August nights, observes an average temperature of 66.7°F (19.3°C).Heat index
Throughout August, the heat index is computed to be a hot 89.6°F (32°C). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. 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. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
