Weather in August
Temperature
Welcoming August, Southall notes an average high-temperature of a still hot 87.3°F (30.7°C), nearly consistent with July's 88°F (31.1°C). In Southall, August's nights observe an average temperature dip to an agreeable 68°F (20°C).Heat index
For August, the heat index is evaluated at a sweltering 100.4°F (38°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial 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.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
