Weather in July
Temperature
A slight uplift in the average high-temperature marks July, adjusting from June's warm 84.7°F (29.3°C) to a tropical 90.5°F (32.5°C). During the nights in July, North Cucamonga records a pronounced shift from the daytime warmth, with a consistent average temperature of 64.8°F (18.2°C).Heat index
July's heat index is evaluated at a hot 93.2°F (34°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
