Weather in November
Temperature
The onset of November marks an average high-temperature of a still hot 33.9°C (93°F), hardly differing from October's 34.9°C (94.8°F). L'Observatoire anticipates a stark contrast in temperature during November nights, with an average low of 21.5°C (70.7°F).Heat index
The heat index value during November is estimated at a blazing hot 50°C (122°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.Realize that the values for the heat index are set for shaded places and light winds. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Take precautions against overexposure. Protection against sun damage is needed. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
