Weather in August
Temperature
Lustre commences August with an average high-temperature of a still warm 82.9°F (28.3°C), maintaining a close resemblance to the previous month. Throughout August, Lustre records an average temperature of 63.1°F (17.3°C) at night.Heat index
The heat index for August is evaluated at 82.4°F (28°C). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
