Temperature

The arrival of October sees a recorded average high-temperature of a still warm 29.6°C (85.3°F), showing little divergence from the previous month's conditions. Throughout October, the average low-temperature dips to a still warm 23°C (73.4°F).

Heat index

In October, the average heat index is calculated to be a torrid 35°C (95°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Take precautions against overexposure. Protection against sun damage is needed. 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. To cut down UV radiation exposure by about half, sport a wide-brim hat.
