June weather forecast
Bostok, French Guiana

With the monsoon looming, June continues the subtle changes from May. The rainy days continue with more uniform distribution throughout the month. The balance between temperatures, daylight hours and wind speeds remains, ensuring comfortable living conditions. June retains equilibrium, showing a pattern similar to the previous five months.

Temperature

Bostok, French Guiana, notes an average high-temperature of a tropical 30.3°C (86.5°F) in June, hardly diverging from May. During June nights, Bostok witnesses a consistent average temperature of 21.1°C (70°F).

Heat index

June's mean heat index is computed to be a blisteringly hot 41°C (105.8°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
