Heat index

The heat index value during October is computed to be a sweltering 35°C (95°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. 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 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely vital to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses.
