Weather in October

October is a tropical autumn month in Mawalgama, Sri Lanka, with temperature in the range of an average high of 30°C (86°F) and an average low of 25°C (77°F).

Temperature

Mawalgama's entry into October measures an average high-temperature of a tropical 30°C (86°F), closely parallel to the preceding month. Mawalgama maintains an average of approximately a warm 25°C (77°F) during October nights, with only a minimal decrease from the daytime temperature.

Heat index

The heat index value during October is computed to be a sweltering 38°C (100.4°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', comes about by integrating the temperature readings with the humidity levels. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
