Temperature

The ushering in of October in Sigiriya brings an average high-temperature of a still hot 32.7°C (90.9°F), closely mirroring the 33.9°C (93°F) of September. Sigiriya observes an average low-temperature of 23.2°C (73.8°F) during October nights.

Heat index

October's average heat index is computed to be a life-threatening hot 45°C (113°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
