June welcomes an average high-temperature of a still tropical 31°C (87.8°F), not much different from the preceding month. Throughout June, Calkini encounters an average temperature drop to a warm 25.7°C (78.3°F).

Heat index

Throughout June, the heat index is appraised at an extremely hot 40°C (104°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses.
