Temperature

As June takes hold, the average high-temperature is a moderately hot 29.7°C (85.5°F), nearly mirroring that of the previous month. Uduvil's nocturnal June readings average at a still warm 28.4°C (83.1°F), showing little variation from the daytime temperatures.

Heat index

The heat index value during June is computed to be a very hot 36°C (96.8°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', offers an insight into how hot it feels when we factor in moisture content. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Humidity

The average relative humidity in June is 78%.

Stay clear of intense sun exposure. Solar protection is of utmost significance. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
