Heat index

For June, the heat index is calculated to be an extremely hot 40°C (104°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Humidity

The average relative humidity in June is 81%.

Take precautions and adopt sun safety practices. Protection against sunburn is obliged. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
