Heat index

November's heat index is estimated at a torrid 37°C (98.6°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for ordinary individuals.
Note: The maximum UV index, 7 during November, leads to the following recommendations:
Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation. Caution! The mirror effect of sand and water ups the UV radiation strength.
