Weather in October
Temperature
The transition into October marks the average high-temperature at a tropical 30°C (86°F), differing minimally from September's 29.1°C (84.4°F). October nights in Welikadamulla document an average temperature reading of 25°C (77°F).Heat index
For most parts of October, the heat index is computed to be a sweltering 38°C (100.4°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', unifies temperature and humidity readings to offer a comprehensive feel of warmth. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
