Weather in August
Temperature
With its high average temperature of 27.1°C (80.8°F) and a low of 17.8°C (64°F), August is regarded as the warmest month.Heat index
August's mean heat index is computed to be 29°C (84.2°F). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. 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 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
