Temperature

November's onset records a minor alteration in the average high-temperature to a still moderately hot 29.8°C (85.6°F) from October's 29.6°C (85.3°F). During November, the nighttime temperature averages of 24.5°C (76.1°F).

Heat index

During November, the heat index is estimated at a fiery hot 37°C (98.6°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.
Note that heat index values are valued for light wind and location in the shade. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. As body temperatures escalate without effective heat release, one might face dehydration threats.

Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat. Caution! Sand and water surfaces escalate the UV intensity from the Sun.
