Heat index

In June, the average heat index is computed to be an extremely hot 44°C (111.2°F). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.
Note that heat index values are valued for light wind and location in the shade. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

The average relative humidity in June is 85%.
