Weather in October
Temperature
The transition into October is marked with an average high-temperature of a still warm 29.6°C (85.3°F), showing an insignificant shift from September's 28.8°C (83.8°F). Thanthirimulla encounters a negligible difference from daytime peaks throughout the October nights, with a low-temperature average of 25.5°C (77.9°F).Heat index
In October, the heat index is appraised at a torrid 36°C (96.8°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant 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.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
