Weather in August
Temperature
The introduction of August notes a subtle temperature variation to a still warm 82°F (27.8°C) from July's 82.9°F (28.3°C). Throughout August, Napoleon's nights cool down to an average of 63.3°F (17.4°C).Heat index
The heat index for August is estimated at a tropical 87.8°F (31°C). Persistent activity under exposure might lead to a feeling of weariness, with subsequent heat cramps.Heat index readings emphasize conditions of light breezes and shaded spots. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
