Weather in October
Temperature
With the onset of October, a modest change to a still moderately hot 29.4°C (84.9°F) from September's 29.5°C (85.1°F) is noted in high-temperature. An average nighttime temperature of 20.7°C (69.3°F) is recorded in Sirimalwatta during October.Heat index
October's heat index is evaluated at a torrid 36°C (96.8°F). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. 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. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly relevant to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
