Weather in August
Temperature
August begins with an average high-temperature of a still warm 28.3°C (82.9°F), reflecting close similarity to the preceding month. Nightly readings in August display a noticeable downturn from daily highs, with the average low-temperature registering a refreshing 15.8°C (60.4°F).Heat index
August's average heat index is estimated at a hot 30°C (86°F). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. 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 'apparent temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
