Weather in July
Temperature
The commencement of July introduces an average high-temperature of a torrid 95.5°F (35.3°C), closely mirroring the preceding month. Throughout July, San Antonio anticipates an average low-temperature of 74.8°F (23.8°C).Heat index
During July, the heat index is computed to be a burning hot 118.4°F (48°C). Keep alert: Heat cramps and heat exhaustion are probable. Heatstroke is a potential danger with continued physical activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
