Weather in October
Temperature
October's average high-temperature stands at a still warm 29.6°C (85.3°F), showing little deviation from September's 29.1°C (84.4°F). Devinuwara records a negligible downturn from daytime temperatures, averaging a low of 25.3°C (77.5°F) in the month of October.Heat index
For most parts of October, the heat index is appraised at a torrid 36°C (96.8°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Sun protection is enhanced with clothing that boasts a tight weave yet offers a loose fit.
