Temperature

Cheyyar's temperature records reveal May as the warmest month, marked by average highs of 40.1°C (104.2°F) and lows of 29.1°C (84.4°F).

Heat index

For most parts of May, the heat index is computed to be a blazing hot 55°C (131°F). Warning: These weather conditions are deemed as overly treacherous, with heatstroke imminent.
Heat index determinations are made taking into account the shade and light air movements. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Humidity

The months with the lowest humidity are May and June, with an average relative humidity of 50%.

UV index

The months with the highest UV index are April through July, with an average maximum UV index of 8. A UV Index of 8 to 10 symbolizes a very high threat to health from exposure to the Sun's UV radiation for the ordinary person.
Note: In May, the maximum UV index of 8 suggests this advice:
Always take precautions; unprotected eyes and skin can be damaged rapidly. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
