Weather in July
Temperature
As Katy transitions from June to July, the average high-temperatures adjust to a still tropical 93.2°F (34°C), nearly the same as the previous 91°F (32.8°C). In July, Katy's temperature tends to fall to an average low of 75°F (23.9°C) during the night.Heat index
For July, the heat index is evaluated at a life-threatening hot 120.2°F (49°C). Stay vigilant: Heat cramps along with heat exhaustion are expected. Heatstroke may follow prolonged exertion.Heat index guidelines indicate values are for light wind scenarios and shaded regions. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
