Temperature

The dawn of June sees an average high-temperature of a warm 29.7°C (85.5°F), subtly contrasting with May's 30.7°C (87.3°F). An average low-temperature of 28.6°C (83.5°F), slightly less than the daytime peak, marks the month of June.

Heat index

In June, the average heat index is appraised at a fiery hot 36°C (96.8°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Humidity

In June, the average relative humidity is 77%.

Rainfall

In Uduthurai, in June, it is raining for 13.7 days, with typically 33mm (1.3") of accumulated precipitation. In Uduthurai, during the entire year, the rain falls for 189.6 days and collects up to 1106mm (43.54") of precipitation.

UV index

The months with the highest UV index are January through September and December, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV rays for the ordinary person.
Note: The UV index of 7 during June leads to these advisories:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
