Temperature

The temperatures reach their highest averages in October, with highs of 34°C (93.2°F) and lows of 21.5°C (70.7°F).

Heat index

In October, the average heat index is estimated at a blisteringly hot 41°C (105.8°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. 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. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly relevant to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
