Weather in July
Temperature
July's advent denotes a minor fluctuation in the average high-temperature to a still moderately hot 29.5°C (85.1°F) from June's 29.2°C (84.6°F). An average low-temperature of 26°C (78.8°F) characterizes Williamsfield's July nights.Heat index
The heat index value during July is evaluated at a fiery hot 36°C (96.8°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
