October weather forecast
Kottawa, Sri Lanka

October, like September, in Kottawa, Sri Lanka, is another warm autumn month, with an average temperature ranging between min 25.4°C (77.7°F) and max 29.7°C (85.5°F).

Temperature

October's average high-temperature stands at a still warm 29.7°C (85.5°F), showing little deviation from September's 28.9°C (84°F). In October, Kottawa's nighttime temperatures demonstrate a slight decrease, stabilizing at an average of 25.4°C (77.7°F).

Heat index

The average heat index in October is appraised at a torrid 37°C (98.6°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

UV index

The months with the lowest UV index are May, June, August and October, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for average individuals.
Note: A daily high UV index of 6 in October leads to these guidelines:
Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
