Temperature

October welcomes an average high-temperature of a still warm 84.6°F (29.2°C), not much different from the preceding month. Nighttime temperatures record an average of 79.7°F (26.5°C) throughout October.

Heat index

Throughout October, the heat index is evaluated at a very hot 95°F (35°C). Emphasize additional safety, risk of heat cramps and heat exhaustion is high. Continuous activity might result in heatstroke.
Realize that the values for the heat index are set for shaded places and light winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Prevent overexposure. Protection from the sun's harmful effects is needed. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses. Beware! Reflections from sand and water can intensify the Sun's UV radiation.
