Weather in August
Temperature
As Katy transitions from July to August, the average high-temperatures adjust to a still moderately hot 82°F (27.8°C), nearly the same as the previous 83.1°F (28.4°C). Katy anticipates a considerable cooling off from the daytime high to an average minimum temperature of 59.2°F (15.1°C) in August.Heat index
The heat index for August is calculated to be a hot 87.8°F (31°C). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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.
