Temperature

The transition from October to November sees average high-temperatures adjusting to a hot 30.9°C (87.6°F), from a not significantly different 29.6°C (85.3°F). Throughout November, the temperature falls to an average low of 24.3°C (75.7°F).

Heat index

Throughout November, the heat index is computed to be a blistering 41°C (105.8°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
In reference to the heat index, it's for places in shade and with a slight wind. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital 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.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Ensure all key precautions. Defense against sun exposure is critical. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat. One must apply and reapply generously an SPF 30+ broad-spectrum sunscreen every two hours or after an outdoor workout or swim. Note! Reflective surfaces like sand and water heighten the UV radiation levels.
