In December, the average heat index is estimated at a hot 31°C (87.8°F). With extended exposure and activity, one might feel exhausted and experience heat cramps.Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity.

Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
