Ingiriya's weather in December, with an average high-temperature of a still warm 28.4°C (83.1°F), subtly shifts from November's 28.3°C (82.9°F). An average low-temperature of 19.9°C (67.8°F) is anticipated throughout the nights during December.Heat index
For most parts of December, the heat index is estimated at a hot 34°C (93.2°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
