Temperature

The start of June marks an average high-temperature of a still moderately hot 85.5°F (29.7°C), hardly distinguishable from the conditions in May. In June, Jayuya records an average nighttime temperature of 75.7°F (24.3°C).

Heat index

In June, the average heat index is calculated to be a torrid 96.8°F (36°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Humidity

In June, the average relative humidity is 78%.

Rainfall

In June, the rain falls for 19.3 days. Throughout June, 2.13" (54mm) of precipitation is accumulated. Throughout the year, there are 249.1 rainfall days, and 28.82" (732mm) of precipitation is accumulated.

UV index

May through October, 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 hazard from unprotected exposure to Sun's UV rays for average individuals.
Note: A maximum high daily UV index of 7 during June translates into the following directions:
Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
