Weather in July
Temperature
July, having an average high-temperature of 87.4°F (30.8°C) and an average low-temperature of 68.5°F (20.3°C), is the warmest month.Heat index
The heat index value for July is computed to be a scorching 104°F (40°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.Realize that the values for the heat index are set for shaded places and light winds. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
