Weather in July
Temperature
With an average high-temperature of 86.4°F (30.2°C) and an average low-temperature of 68.2°F (20.1°C), July is the warmest month.Heat index
For most parts of July, the heat index is computed to be a sweltering 100.4°F (38°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes.

Opt for tightly woven and loose clothing to enhance protection from the Sun.
