Weather in July
Temperature
The onset of July marks an average high-temperature of a still tropical 91.4°F (33°C), hardly differing from June's 90.7°F (32.6°C). In the month of July, Johnson records a consistent average low-temperature of 72.5°F (22.5°C).Heat index
During July, the heat index is calculated to be a burning hot 114.8°F (46°C). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses.
