Temperature

Heat index

Throughout July, the heat index is estimated at an extremely hot 109.4°F (43°C). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.
Always consider that heat index estimations are for light winds and places in the shade. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
