Weather in July
Temperature
July brings the highest temperatures, with an average high of 94.5°F (34.7°C) and an average low of 59.5°F (15.3°C).Heat index
The heat index in July is appraised at a very hot 100.4°F (38°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
