Weather in August
Temperature
The average high-temperature during August matches that of the preceding month. In Vallipuram, the average low-temperature during August nights tends to settle at a still moderately hot 27.6°C (81.7°F), indicating a slight drop from the daytime peak.Heat index
The heat index value during August is appraised at a sweltering 35°C (95°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.Note that heat index values are valued for light wind and location in the shade. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. 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 meaningful for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
