Weather in July
Temperature
In Godfrey, the peak average temperatures are observed in July, with a high of 85.3°F (29.6°C) and a low of 67.6°F (19.8°C).Heat index
Throughout July, the heat index is evaluated at a very hot 96.8°F (36°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, 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 extremely significant for babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
