June weather forecast and climate
Rioviejito, Colombia

The first month of the summer, June, is also a hot month in Rioviejito, Colombia, with average temperature fluctuating between 31.7°C (89.1°F) and 20.9°C (69.6°F).

Temperature

In June, the average high-temperature is practically the same as in May - a still tropical 31.7°C (89.1°F). In June, the average low-temperature is 20.9°C (69.6°F).

Heat index

The average heat index in June is computed to be a very hot 39.2°C (102.6°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Note that heat index values are valued for light wind and location in the shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like', 'apparent temperature', 'real feel', or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Additional factors like activity, metabolic differences, wind, and clothing affect individual temperature impact. 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 especially crucial for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. If the body can not disperse the excessive heat and body temperature reaches conditions of hyperthermia, above 37.5°C (99.5°F) to 38.3°C (100.9°F), thermal conditions are potentially life-threatening.

Humidity

In June, the average relative humidity is 69%.

Rainfall

In Rioviejito, during June, the rain falls for 18.8 days and regularly aggregates up to 106mm (4.17") of precipitation. Throughout the year, in Rioviejito, there are 233 rainfall days, and 1320mm (51.97") of precipitation is accumulated.

UV index

January through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health risk from unsafe exposure to the UV radiation for the ordinary person.
Note: In June, the average maximum UV index of 7 translate into the following recommendations:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. A wide-brim hat offers excellent sun protection for eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Tightly woven, loose-fitting clothes provide additional protection from the Sun.
