Despite peaking in the previous month, the sunshine hours still remain significant.

Temperature

Temperature records mark July as the warmest month, with highs averaging 91°F (32.8°C) and lows at 73.6°F (23.1°C).

Heat index

In July, the heat index is evaluated at a blistering 109.4°F (43°C). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are primarily vital for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
