Temperature

Palampiddi indicates an average high-temperature of a still tropical 31.2°C (88.2°F) in May, showing minor variation from April's 31.4°C (88.5°F). Palampiddi's nighttime temperatures in May see a subtle dip to an average of 28.1°C (82.6°F).

Heat index

The heat index value during May is computed to be a blistering 40°C (104°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. 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.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

In May, the average relative humidity in Palampiddi is 77%.

Note: In May, a regular UV index of 7 translates into these guidelines:
Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
