Weather in August
Temperature
The months of July and August are noted for their lowest temperatures, with an average high-temperature of 28.9°C (84°F).Heat index
The average heat index in August is estimated at a torrid 35°C (95°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Heat index's context suggests values are appropriate for shady areas and slight breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
