Weather in October
Temperature
During October, the average high-temperature is a still moderately hot 29.4°C (84.9°F), maintaining a close resemblance to that of the preceding month. Lewella observes an average nighttime low-temperature of 20.7°C (69.3°F) during the month of October.Heat index
The heat index value during October is estimated at a very hot 36°C (96.8°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. 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.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
