Weather in san juan puerto rico in june: Puerto Rico June Weather, Average Temperature (Puerto Rico)

June Weather forecast – Summer forecast

The first month of the summer, June, is still a warm month in San Juan, Puerto Rico, with temperature in the range of an average low of 78.3°F (25.7°C) and an average high of 84.2°F (29°C).

Temperature

In June, the average high-temperature is relatively the same as in May – a still moderately hot 84.2°F (29°C). In June, in San Juan, the average low-temperature is 78.3°F (25.7°C).

Heat index

The average heat index in June is computed to be a torrid 95°F (35°C). Take special precautions – heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. 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’, ‘felt air temperature’, ‘real feel’, or ‘apparent temperature’, is a measure of how hot it feels when the actual air humidity is factored in. Additional factors like wind, differences in body mass, height, and shape, clothing, and activity influence one’s weather impression. 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. Excessive warmth is eliminated from the body by evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. If the body can not disperse the excessive heat and body temperature reaches conditions of hyperthermia, above 99.5°F (37.5°C) to 100.9°F (38.3°C), thermal conditions are potentially life-threatening.

Humidity

May through July, with an average relative humidity of 79%, are the most humid months in San Juan.

Rainfall

In San Juan, it is raining for 10.3 days, with typically 0.71″ (18mm) of accumulated precipitation. In San Juan, during the entire year, the rain falls for 159.9 days and collects up to 12.01″ (305mm) of precipitation.

Ocean temperature

In San Juan, the average seawater temperature in June is 82.9°F (28.3°C).
Note: Water temperature between 77°F (25°C) and 84.2°F (29°C) is regarded as very warm and enjoyable by all. With these temperatures, water activities are pleasurable, without feeling uncomfortable for prolonged periods.

Daylight

With an average of 13h and 13min of daylight, June has the longest days of the year.
On the first day of the month, sunrise is at 5:47 am and sunset at 6:57 pm. On the last day of June, in San Juan, sunrise is at 5:51 am and sunset at 7:04 pm AST.

Sunshine

The month with the most sunshine is June, with an average of 10. 9h of sunshine.

UV index

The months with the highest UV index are April through November, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high health hazard from exposure to the Sun’s UV radiation for the average person.
Note: In June, the average maximum UV index of 7 translate into the following recommendations:
Take precautions against overexposure. Protection against sun damage is needed. 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 the 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. Beware! The reflection of water and sand dramatically increases exposure to the UV rays.
