Weather in July
Temperature
Casey's warmest weather arrives in July, when temperatures average a high of 82.2°F (27.9°C) and a low of 64.9°F (18.3°C).Heat index
July's heat index is evaluated at a tropical 89.6°F (32°C). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
