Temperature

May, recognised by an average high temperature of 38.6°C (101.5°F) and a low of 28.8°C (83.8°F), is Vallam's warmest month.

Heat index

In May, the average heat index is computed to be a life-threatening hot 53°C (127.4°F). Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.
One should consider that heat index numbers are for shaded settings and light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance to children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
