June weather forecast
Chennai, India

June in Chennai doesn't stray far from May's heat, as temperatures narrowly dip to 34.2°C (93.6°F) while embracing more humidity. With the escalation of rain, the city gradually prepares for the monsoon setting in. Despite having the longest daylight span, the sunlight isn’t unpleasantly harsh, courtesy of increased cloud coverage. The wind continues its robust strides, carrying occasional wafts of cooler sea air inland. Given Chennai’s geographical positioning, June persuasively demonstrates the tropical character of its weather.

Heat index

The heat index for June is evaluated at a scorching 44°C (111.2°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.
Know that the heat index computations account for shaded terrains and slight winds. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Don't neglect protection; skin and eyes can be burned swiftly if left exposed. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays. Attention! UV strength is notably upped by the reflection of sand and water.
