Weather in July
Temperature
The average temperatures reach their apex in July, averaging 87.4°F (30.8°C) at the high end and 69.6°F (20.9°C) at the low end.Heat index
In July, the heat index is calculated to be a very hot 98.6°F (37°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
