Heat index

May's mean heat index is calculated to be a hot 31°C (87.8°F). Unrelenting activity during exposure could cause fatigue and potentially lead to heat cramps.
Know that the heat index computations account for shaded terrains and slight winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
