Weather in July
Temperature
The month of July sees the highest average temperatures, reaching 86.4°F (30.2°C) at the peak and 68.2°F (20.1°C) at the low.Heat index
The average heat index in July is calculated to be a fiery hot 100.4°F (38°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.The standards for the heat index are set for locations in shade and under light breezes. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
