Heat index

During November, the heat index is evaluated at a very hot 37°C (98.6°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Note: A daily high UV index of 10 in November leads to these guidelines:
Prioritize protection; rapid damage can occur to unprotected eyes and skin. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes. Despite the clouds, sunscreen with an SPF of at least 30 should be used liberally and reapplied frequently, especially after a swim or outdoor workout.
