Weather in July
Temperature
July is the month when Lewis sees the highest average temperatures, with a high of 83.8°F (28.8°C) and a low of 66.4°F (19.1°C).Heat index
The heat index in July is appraised at a sweltering 95°F (35°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Note that heat index values are valued for light wind and location in the shade. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
