The arrival of June coincides with an average high-temperature of a still hot 31°C (87.8°F), indicating a minimal shift from May's 31.8°C (89.2°F). Naula, in June, experiences an average temperature of 22.8°C (73°F) at night.

Heat index

The heat index in June is calculated to be a fiery hot 39°C (102.2°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
