Weather in August
Temperature
August, with its high-temperature average of 29.7°C (85.5°F) and a low-temperature average of 25.1°C (77.2°F), is the warmest month.Heat index
For most parts of August, the heat index is evaluated at a torrid 36°C (96.8°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
