Weather in July
Temperature
Julien Hill's July weather reaches an average high of 87.3°F (30.7°C) and an average low of 68.5°F (20.3°C), making it the warmest month.Heat index
The heat index for July is estimated at a fiery hot 102.2°F (39°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
