Temperature

Entering November, the average high-temperature is recorded at a warm 29.8°C (85.6°F), exhibiting a minimal shift from October's 30.8°C (87.4°F). An average nighttime temperature of 19.3°C (66.7°F) is witnessed throughout November.

Heat index

During November, the heat index is estimated at a very hot 35°C (95°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Precautions are essential; the risk of damage to unprotected skin and eyes is too high. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. Applying and reapplying a broad-spectrum sunscreen with a minimum SPF 30 after every two hours, outdoor workout, or swim is recommended.
