October weather forecast
Kurunegala, Sri Lanka

October stands out as Kurunegala's wettest month with rainfall soaring to 267mm (10.51") from 72mm (2.83") in September. Correspondingly, the number of rainy days also significantly hikes. Despite the surge in precipitation, the city's temperatures hold steady, continuing the warm tropical environment. The notable increase in cloud cover correlates directly with the heightened rain levels. The wind speed reduces during this period, providing less of the cooling effect compared to drier months.

Temperature

October's climate shows a minor adjustment in average high-temperatures to a still tropical 30.9°C (87.6°F) from September's 31.2°C (88.2°F). An average nighttime temperature of 21.8°C (71.2°F) is recorded during October.

Heat index

For October, the heat index is evaluated at an extremely hot 40°C (104°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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 physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
