June weather forecast
Puerto Rico, Bolivia

June, the first month of the winter in Puerto Rico, is still a tropical month, with an average temperature varying between 30.7°C (87.3°F) and 20.2°C (68.4°F).

Temperature

The arrival of June sees a recorded average high-temperature of a still tropical 30.7°C (87.3°F), showing little divergence from the previous month's conditions. The average nighttime temperature lowers to an agreeable 20.2°C (68.4°F) throughout June.

Heat index

Throughout June, the heat index is computed to be a sweltering 39°C (102.2°F). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Humidity

In June, the average relative humidity is 78%.

Rainfall

In Puerto Rico, in June, during 12.1 rainfall days, 32mm (1.26") of precipitation is typically accumulated. Throughout the year, there are 233.4 rainfall days, and 1251mm (49.25") of precipitation is accumulated.

UV index

January through June and December, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index value of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV rays for the average person.
Note: An average UV index of 6 in June transforms into this advice:
Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Boost your sun resistance with garments that are densely woven yet spacious.
