Weather in August
Temperature
The warmest time of the year is August, with temperatures averaging a high of 95.2°F (35.1°C) and a low of 74.8°F (23.8°C).Heat index
August's heat index is calculated to be a scorching 109.4°F (43°C). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.In terms of the heat index, values are set with light wind and shade conditions in mind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for babies and toddlers. 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.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
